elational Databases in e-Commerce
Of the many uses of relational databases throughout enterprise software their use for supporting e-commerce initiatives and programs provides a foundation for assessing their performance at diverse data and taxonomy management, and scalability of transactions as well. The scalability, security and speed of relational databases when used for e-commerce tasks push them to the limits of performance and customization as well. An example of this is the widespread use of relational databases in creating and sustaining distributed order management systems (Connolly, Begg, 2006).
As e-commerce sites including Amazon.com, Apple, Dell, Expedia and others all rely on a series of catalogs that are unified through a common series of taxonomies. These catalogs and their taxonomies they are part of define how the logic and workflows of the distributed order management system operates over time. elational databases, many of them integrated to at the logical records level, are…… [Read More]
They in short link and map ideas that already exist, creating real time answers to questions as they are applied to new and archived knowledge or action plans.
According to IDC reports, most data warehouses will be stored in a columnar fashion and not in rows, reporting and data collection problems will be solved with databases that have no formal schema at all, horizontal scalability through clustering will be achieved by large-scale database servers; and most OLTP databases will either reside entirely in memory or be augmented by an in-memory database. These new systems will encourage companies to forget disk-based partitioning schemes, buffer management, indexing strategies and embrace a world of large-memory models, many processors with many cores, clustered servers and highly compressed column wise storage.

Standard-elational and Object-elational Databases
Software development has experienced evolution over the past few decades given the increasing demands for better information systems in today's society, especially in the modern business environment. The evolution of software development during this period has also been influenced by the tremendous changes in the ways with which computers are used and programmed. The changes in software development have contributed to the emergence of different categories of databases, which are basically defined as repositories for assorted but interrelated pieces of data or information. Through the evolution of software development, database management systems have been transformed. The most common classifications of databases emerging from the transformation of database management systems include standard-relational and object-relational databases.
Standard-relational databases are those that support interactive data structures and utilize data manipulation language that is akin to relational algebra with regards to its power. Since they utilize powerful data manipulation language,…… [Read More]
Compare and contrast Microsoft Access, Microsoft SQL Server, DB2, and Oracle database programs
Providers: Microsoft Corporation provides Microsoft Access and SQL Server, Oracle by Oracle Corporation and DB2 is a product of IBM.
Brief about each:
MS Access: Microsoft Access is a database, which comes bundled in Microsoft Office Products. Access is fully compatible with Active Server Pages (ASP) scripting. Database programs such as Access (sometimes called Relational Database Management systems or RDBMS) are used to store information, often large amounts of information. It can be used as a flat-file database (using a single table) or a relational database (using more than one table linked together). Access database applications can be produced for a large number of database situations including financial and scientific data - with excellent results. Access comes equipped with Wizards, which help the novice to create tables, forms, queries and reports. A complicated relational database…… [Read More]
Databases and their relational file structures have also progressed to the point of being open in architectural structure enough to allow for real-time updates via XML calls and integration points throughout individual and shared files (oth, Hernandez, Coulthard, Yan, et al., 2006). This open architecture-based approach to XML integration is also making databases ideally suited for transaction-intensive environments throughout e-commerce websites and throughout complex transactions involving multiple selling partners through a supply chain as well (Smyrlis, 2005). As a result, databases are the foundation of distributed order management, enterprise content management, enterprise resource planning (EP) and Customer elationship Management (CM) systems.
Databases and Security
Databases in organizations and governments often hold the most confidential data that exists and therefore need to be protected extremely well. The dominant standard for database security is ACID (atomicity, consistency, isolation, durability) compliance (Dolgicer, 1993). When an ACID test of compliance is completed on a…… [Read More]
Microsoft supports distributed component objects via distributed COM (DCOM). DCOM use remote procedure calls to organize data between processes and computers so that components appear to have the same word size, bit orientation, and address space. DCOM is a direct competitor to CORA, discussed next.
V. Common Object Request roker Architecture (CORA)
CORA is OMG's open, vendor-independent architecture and infrastructure that computer applications use to work together over networks (CORA asics). Using a standard protocol, a CORA-based program from any vendor, on almost any computer, operating system, programming language, and network, can interoperate with a CORA-based program from the same or another vendor, on almost any other computer, operating system, programming language, and network.
The core foundation of CORA is the Object Request roker (OR) that provides an interface between requesting objects and receiving objects (CORA, TechTarget). OR support in a network of clients and servers on different computers means…… [Read More]

Databases and egulatory Compliance Challenges
The advent of technology has increased the popularity of database usage in firms, yet the legislation regulating the field has yet to be finalized. The changing nature of the IT sector, coupled with the legislative traits, creates several situations in which the companies find it difficult to comply with the regulations. This paper recognizes some of those difficulties, and also proposes some solutions.
egulatory challenges for databases
No sector in the modern day society evolves as rapidly as the technologic domain. And the innovations developed at this level come to impact all aspects of life, from the spending of the leisure time to the completion of the most challenging professional tasks.

This would also mean that the shadowing process goes on behind the scenes, and one need not even be aware that the process is in fact going on at any point of time; it can go on without creating any sort of disturbance to the user of the application, at any point of time. (Shadow Files)
Another important advantage of using the shadowing of a database is that data would be immediately available, even when the primary database has failed due to some reason or another. Non-exclusive usage of the primary database is also permitted, and this means that the database will not be locked, and this in turn means that it can be updated and changed during the process of its creation. Computer resource can be conserved, and this is because of the fact that shadowing does not use any separate process; the database process gives the shadow database…… [Read More]

Analysis and Overview of Database ystems in the Enterprise
The pervasive adoption of databases for aggregating, analyzing, parsing, reporting and storing data continues to exponentially increase over time, as the information needs of companies continued to increase. The foundation fo nearly every enterprise-wide system and computing platform includes integration to databases of many types, from object-oriented to relational (Lungu, Velicanu, Botha, 2009). Every Enterprise Resource Planning (ERP) system today relies on databases for product, pricing, costing, production scheduling, service coordination and manufacturing execution task coordination as well (Bremer, Carey, 1987). Databases have become an essential component of every enterprise system in use today, from coordinating supply chains, sourcing, production and tracking customer activity and sales through Customer Relationship Management (CRM) systems (Madduri, hi, Baker, Ayachitula, 2007). Object-oriented databases are pervasively used in Computer-Aided Drawing (CAD) applications as well, given their speed and accuracy in managing geographic and graphic primitives…… [Read More]
To implement this algorithm, it is essential to simulate locking of what the books mentions as an item X that has been transcribed by transaction T
is either committed or aborted. This algorithm is not what would turn into deadlock, for the reason that T. waits for T
only if TS (T) > TS (T
) (Elmasri, 2011).
According to the book, strict timestamp ordering differs from basic timestamp ordering because basic timestamp ordering is utilized whenever some transaction T. attempts to subject a read item (X) or a write item (X) operation, the basic to algorithm is the one that compares the timestamp of T. with read_TS (X) and write_TS (X) to ensure that the timestamp where as the strict timestamp does not. Another difference is the fact that the basic lets us know that if the proper order is violated, then transaction T. is the one…… [Read More]
Comparing Microsoft Access, SQL, IBM DB2 and Oracle databases is presented in this analysis, taking into account the key features of ACID Compliance, Data partitioning, interface options, referential integrity, operating systems supported, and support for transactions and Unicode. Each of these factors is initially defined followed by a table comparing them across the database types.
Definition of Comparison Factors
At their most fundamental level, all databases have support for relational data models and the ability to index data through the use of a wide variety of taxonomies or organizational structures (Basumallick, Wong, 1996). elational Database Management Systems (DBMS) however all have the ability to manage transactions with the greatest efficiency given the design of these systems to support multiple transactions at once, running concurrently from each other. The characteristic of an operating system being able to manage thousands of concurrent transactions at the same time is often referred…… [Read More]
Visual Basic Scripting Edition, also known as VB Script is a common and popular scripting language based on Microsoft's Visual Basic. VB script is considered lightweight, and easy to use and is interpreted at very rapid speeds. The language of VB Script is mostly not dependent on case or syntax, making working with tool very easy. The use of VB Script and scripting in general is very beneficial in many computing applications, especially for databases, as the rest of this summary will focus on to highlight the repetitive tasks that can be handled with a well written script.
Adding and deleting raw data into a database can be significantly enhanced with a useful script that assists in the immediate sorting and filing of the data. The more complex and complicated the data, the more valuable the scripting comes into play. This same idea can be used when it is necessary…… [Read More]
These personal productivity systems also tend to be islands of customer data that need to be integrated into larger customer information systems to be effective (Zahay, 2008). Enterprise-class DBMS are capable of integrating to broader process workflows due to their underlying technical design. In addition, these DBMS are often used for more advanced customer strategies including data mining, business analytics of customer bases, and the development of long-term loyalty campaigns. All of these types of analysis are not possible on the personal productivity class of databases. The limitations of enterprise DBMS however are the their cost for implementing in larger companies, and the need for training users how to use the many functions in these databases.

elational satisfaction as a function of relational maintenance techniques and relational satisfaction as a function of type and frequency of contact between spouses.
There are two contradictory maxims that complicate the military phenomena: the first is "out of sight out of mind." The second is "absence makes the heart grow fonder." As applied to the military situation with one spouse separated from the other over long periods of intermittent time, the first maxim denotes that connection of one spouse to the other will be weakened, whilst the second maxim indicates that the opposite effect will occur and that their relationship will be strengthened due too the intensity of their longing for one another. Most research studies on military relationships seem to tend to the former indicating that the marital dynamics often seem to be at risk due to the periodically long and consistent separation of one spouse from the other…… [Read More]
A patchwork of laws provided narrow privacy protections for selected health data and certain keepers of that data." (Administrative Simplification in the Health Care Industry) Therefore, new technologies such as relational databases have simplified the data gathering and maintenance processes of all types of healthcare related data like the physician information process. It is not unheard of today for healthcare and insurance providers matching or 'sinking data' on a monthly or quarterly basis because of the availability of better communication capabilities as well as compatible database comparison processes.
Even the doctors themselves have access to providers' systems and databases today. Through automatic telephone systems, business to business Internet portals, and tape or disk delivery processes, all of a physician's personal, office and patient information can be updated easily. In many cases, the entire process including security and confirmation is a completely hands free operation. In other words, without human intervention,…… [Read More]
Building a Database for Use in Scheduling Process
The scheduling of various activities can at the moment be with the help of computer programs that implement the methodology of the critical-path method (CPM) (Choo et al.,2008). The requirements for building a database for use in scheduling process are numerous. For instance, each scheduler must have a separate database for storing information persistently. The server administrator and the application scheduler have the choice as well as location of database to be used. The performance of a scheduler is largely affected by the performance of the chosen database. If more tasks per second are needed then the scheduler daemons can be run on larger and faster systems.
According to Johnson (2004), the requirements for building a database for use in scheduling process include ensuring the following;
The scheduler database and service must be configured have a high level of availability by…… [Read More]
What is emerging is the use of databases as the means for making strategic plans more accomplishable through more efficient and targeted use of data. From the strategic use of SO architectures and platforms to the highly tactical approach to re-defining data models that allow for greater agility and flexibility in managing complex data mining requests, the use of databases is going through a transformational phase as they become critical to the attainment of strategic plans for organizations worldwide.

rich society, database management is an ever-expanding and increasingly important field. This paper discusses databases, database management systems (DBMSs), and their importance in today's society. Additional topics include the need for security, concurrency, and control within database management, as well as the role of the database administrator.
A database can be defined as "a structure that can house information about multiple types of entities, the attributes of these entities, and the relationships among the entities" (St. Edward's University). Databases can contain a wide variety of information. For example, a university database may include information about students, courses and classrooms. Further, this university database may contain significant amounts of information about the relationships between these entities, such as student course enrollment, and the use of classrooms for courses (amakrishnan).

This research proposal looks to determine how the selection of a given cloud platform impacts user intention, satisfaction and long-term adoption.
In order to evaluate the contributions of each of these platforms, each is briefly reviewed within the context of this literature review. First, the most commonly used one in start-up cloud database service providers, Amazon Web Services (AWS), is analyzed. AWS is comprised of the following components: Amazon DynamoDB and SimpleDB Services, Amazon Elastic Cloud Service (EC2), Amazon Elastic Block Store (EBS), Amazon Simple Storage Service (S3), Amazon elational Database Service (DS) and Amazon SQS. Amazon has also developed a cloud-based content sharing service that capitalizes on the depth of database expertise and support in this platform. Called Amazon CloudFront, this specific Web Service is designed to allow for Amazon ElastiCache configuration and use of a secured Cloud DNS service called oute 53. All of these technologies are combined…… [Read More]
ACID Compliance in Databases
When a databases' data structures support the qualities of atomicity, consistency, isolation and durability (ACID) the database technology and underlying structure is said to be ACID compliant. These attributes are essential for the successful operation of a true relational database. Personal experiences of configuring and using a distributed order management system, where the order state engine must track specific tasks and orders, illustrates just how critical ACID compliance is. Without ACID compliance, the orders would collide with one another in the data structures of the system and it would quickly descend into a computerized, chaotic mess.
Analysis of ACID Components
The attributes of atomicity, consistency, isolation and durability are essential for any enterprise-class software system to scale across thousands of users and be deployed across a wide variety of departments and locations. Atomicity is essential for the distributed order management application mentioned earlier for example. The…… [Read More]

Neo-looked confused. "Programs hacking programs?" To which the Oracle replied, "At some time, a program was written to govern everything. The only time you see a program is when it's malfunctioning, and needs to be replaced, or exiled." Jack, I know you are new in the IT department, but I can't emphasize enough the need for you to take the Oracle's advice. We want our software, CRM modules, and sales processing databases to function without being seen. We don't need any programs fowling up other programs. I don't want to have to fight any 'vampires' or 'ghost twins' because you have allowed the database data dictionary to get corrupted.

Implementing an Enterprise Database Management System
Enterprise Database Management Systems (DBMS) are the catalyst and foundation of many of the enterprise software applications, platforms and enterprise systems in place today. Having progressed from being a relational database in the past to often being used as the foundation for complex process workflow and transaction systems (Casati, Castano, Fugini, 2001) the DBMS architecture has taken on a central role in enterprise computing. The intent of this paper is to analyze the DBMS implementation critical success factors in enterprises, in addition to analyzing the advantages and disadvantages of enterprise DBMS systems and platforms.
Analysis of DBMS Implementation in the Enterprise
In many respects the critical success factors of Enterprise esource Planning (EP) systems reflect or mirror those for DBMS systems, as the latter systems are often platforms for EP applications (Lungu, Velicanu, Botha, 2009). When DBMS systems are implemented, it requires…… [Read More]
Oracle sells software for database-management and network products, application-development productivity tools, and end-user applications. Its principal product, the Oracle relational database-management system, runs on supercomputers, mainframes, minicomputers, microcomputers, and personal computers. The firm also offers consulting and systems-integration services. Foreign sales make up about 50% of revenue.
Oracle sees the wisdom in managing business data. Oracle also offers business applications for data warehousing, customer relationship management, and supply chain management. The company made an unsolicited bid to acquire PeopleSoft for about $5.1 billion in June 2003. y early 2004 the offer had increased to $9.4 billion, but was later reduced to $7.7 billion to reflect market conditions. The Department of Justice filed antitrust lawsuits in seven states to block the deal, and started hearings on June 7. Peoplesoft's lawsuit against Oracle is scheduled to go to court November 1 in Alameda, California.

In the contemporary business environment, the accounting profession has undergone a fundamental change, and the traditional accounting systems are no longer adequate to satisfy a recent accounting domain. Thus, a call has been made to expand the scope of accounting information systems. In response to the call, the REA data model was launched to support the accounting information systems. The REA data model is identified as the conceptual modeling tool that assists in designing the AIS (accounting information system) database. The REA model is specifically good to develop an invoicing and billing process.
The objective of this project is to use the REA data model to develop the database for the billing and invoicing process.

A relational database systems is one that allows a firm to maintain data and link it in diverse and functional ways (Wambler, 2015). Different data categories will link/relate to others, which is where the name relational database comes from. By linking the tables, code can be written and applied that searches for categories of data connections that tell the firm something about the users or consumers of their product. For example, online users of online stores and sending out signals of data that can be collected and stored in a relational database. This data tells the firm everything from where the consumer is located to what sort of sites he visits (cookies enable this to happen), to what he is looking at in the online store, etc. The firm collects information on the individuals without the individual even knowing it and the firm then pools all of this…… [Read More]
Database Distribution Strategy
Smart Homes, Inc. required a database distribution strategy for its exciting new home thermostat product. As part of initiatives to develop and establish this database, the firm has created its own Web-based system for registering, evaluation, and controlling a user's thermostat through a mobile computing device. The database design must support a smart thermostat registration system that would support some customer service processes. For instance, when a customer installs and powers on the smart thermostat, the device links to his/her home network and sends distinctive device and environment information to the Smart Home, Inc. system. Moreover, the database must support the collection of smart thermostat data like current temperature, energy usage, humidity, thermostat location, and user-programmed temperature schedule.

Cloud computing applications often need to have a 99.999% uptime as customers use them directly over the Internet, and there is little chance of solving problems from a remote location (McAfee, 2011). As a result, databases used in cloud computing must have a very high level of reliability and be capable of managing small errors that would cause other databases to stop working or need to be rebooted. The requirement from cloud computing users for databases to be able to manage these higher levels of reliability is leading to a completely different level of research and development today (Limbasan, Rusu, 2011). Taking into account all of these factors it is clear that cloud computing is having a very disruptive effect on database research, development and use today. Cloud computing is forcing many enterprise software vendors who create databases to focus more on how their applications can be used as more…… [Read More]
NoSQL Databases Live Up TO Their Promise? (Leavitt, 2010) the author presents a fair and balanced analysis of the NoSQL database technologies and supporting Big Data platforms including Cassandra and HBase (the precursor of Hadoop) with accuracy and clarity. The author also points out that despite the cost advantages of NoSQL and its inherent strengths in managing massive amount of unstructured content, its limitations from an enterprise computing perspective including overhead and complexity, consistency including support for atomicity of data and support for the industry-wide ACID framework are lacking (Leavitt, 2010).
The comparison of SQL vs. NoSQL database technologies is well-done in the article, pointing out how NoSQL excels at managing object-, image and textually-based data while the former excels at structured data and the speed of transactions. The article does not mention however how the complexities of managing batch-oriented processes of very large data sets vary between the two…… [Read More]

Miller Inc. looks forward to creating a data repository for all data collected that is beyond the current relational database it currently uses. The company has currently outgrown the relational database in Oracle that it currently uses. Though it enables data to be stored in different tables that can be linked together using record keys, the amount of keys and records makes it difficult to operate a standard relational database. The company thus needs to adapt database modeling in designing their data warehouse. This is the project. Data modeling extends the online transaction processing models that are common in relational database into data warehousing. The project goal is to develop an appropriate database schema to be designed alongside other components such as identifying metadata. The IT role is to model the data warehouse, implement and test it.

egardless of numerous efforts to define data, knowledge, and information, there are still some uncertainties and lack of clarity regarding what these three things are and the relationships that exist between them. While many descriptions of the three are relevant, most of these definitions are far from providing the clear picture of what the three really are. However, there are considerable differences between data, knowledge, and information though they have some relationships between them. The main relationship is that data is described in relation to information, information defined on the basis of data and knowledge, and knowledge explained in terms of information.
The differences between data, knowledge, and information can be explained in terms of their basic definitions, purposes, and how each is formed. Under definitions, data can be described as basic, unprocessed, and unfiltered information whereas information is described as more developed data that has evolved to a…… [Read More]

In order to support the end-user database application, the user must maintain files like Adobe, Acrobat (pdf), PostScript, and FrameMaker to rapidly setup, test, modify, run, save and print database. Microsoft Excel files are also needed to enable information distribution in spreadsheet form and mark-up files (e.g., HTML, XML, etc.). There is no need to learn a programming language or meta-language and the setup can be accomplished by using a graphical user interface (GUI).
The most popular way to design a database is through Relational DMS, which provides a collection of operations to manipulate relations, where data is presented as a collection of relations. A table depicts each relation, attributes as Columns, and Rows ("tuples") represent entities. Among the main features and functions of the software include: Supports various configurations (single-user, networked multi-user, and client-server); Ease of installation and distribution; Transaction processing; High speed…… [Read More]
"Sometimes abbreviated as WP, a word processor is a software program capable of creating, storing, and printing documents. Unlike the standard typewriter, users using word processors have the ability of creating a document and making any changes anywhere in the document. This document can also be saved for modification at a later time or to be opened on any other computer using the same word processor. (Computer Hope, 2011)" Microsoft's Word is a word processor and there are other ones as well such as Apple iWork, Corel WordPerfect, and Sun StarOffice. Amongst the various office automated systems, the word processor is one of the most used thereto.

Each of the databases exports a view of its tables or objects that conforms to the shared data model, so that queries can be expressed using a common set of names for properties and relationships regardless of the database. The queries are then translated so that they are actually run against the local data using local names in the local query language; in the reverse direction results may be scaled, if needed, to take account of a change of measurement units or character codes (Applehans, et al. 2004). The technological test of these systems is to create programs with the intelligence necessary to divide queries into sub-queries to be interpreted and sent to local databases, and after that to merge all the results that come back. Great progress has been made in methods for setting up efficient dispersed query execution and the constituent that does this is frequently called an…… [Read More]
If the existing process of Access and Excel are not meeting our database then the implied convenience is still representing a higher cost in terms of purchase price, implementation and maintenance. With the recent advances in FoxPro's basic package, we should consider the additional power available from Visual FoxPro.
Excel & Access Combination
Access and Excel offer features like: data filtering, sorting and grouping, dynamically generates SQL code, saves ad-hoc database reporting queries, stores temporary ad-hoc database reporting tables and much more.
The combination of Excel and Access is certainly at the low end of the database market in terms of how robust the database is with speed and performance. However, the bigger advantage of Microsoft Access and Excel having the ability to integrate data with the other Microsoft Office products and the strong end user tools that are easy to use give line management an ability to create their…… [Read More]

When it comes to strategic information management, there are many options that a company has. Data mining, data warehousing, and the various OLAP options are only some of the tools that can be used, but they are three of the most important - if they are used correctly. Because there are several options with OLAP it is very versatile and most companies can find a way to make it work for them so that they can quickly get the answers that they are looking for and help to keep their company moving forward. The other two business intelligence tools, data mining and data warehousing, are also very important, but like any of the other tools there are contributions that they offer and drawbacks that they have. The key to using them all effectively is getting a good understanding of what they can bring to an organization and what they…… [Read More]
Particularly with the relatively recent passage and renewal of the nation's 2002 Homeland Security Act, individual Americans are becoming more and more concerned that their retrieval and use of information is being tracked, not simply through the paper libraries of the nation, but also via the orld ide eb. However, although there is a concern that one can leave one's information imprint and compromise one's privacy when tracking relevant data -- for instance, a student researching hate groups could be unfairly targeted as a potential sympathizer with such organizations, if he or she leaves a 'track' on his or her high school's hard drive -- one cannot ensure that no data fingerprints are left upon personal or public hard drives or search engines themselves when users access data via large-scale data warehouses.
Until the last few years, data warehousing traditionally focused on relational technology, namely the storing large amounts of…… [Read More]

relationships and distinctions between the information systems concepts of data warehousing and data mining, which combined with online analytical processing (OLAP) form the backbone of decision support capability in the database industry. Decision support applications impose different demands for OLAP database technology than the online transaction processing (OLTP) model that preceded it. Data mining with OLAP differs from OLTP queries in the use of multidimensional data models, different data query and analysis tools at both the user-facing front end and the database back end, and different mechanisms for data extraction and preparation before loading into a data warehouse can take place. The construction of data warehouses entails the operations of data cleaning and data integration, which are key pre-processing steps for enabling data mining. Furthermore, the concept of metadata (data about data) is essential to the functioning of a data warehouse, and must be managed appropriately for an effective and…… [Read More]

Capitalizing on Elastic Computing
Aside from its potential to integrate and aggregate a host of resources and technologies, Cloud Computing can most prominently benefit the enterprise through the enabling of Elastic Computing.
Elastic Computing is the utilization of the Cloud's nearly limitless scalability to provision resources on demand and at scale without conventional architectural concerns associated with doing so on-premise such as:
Scaling Up and Down -- In physical environments, substantially adding or subtracting resources requires reconfiguring one's architecture to do so -- which is time consuming. Moreover, it is possible that after reconfiguring architecture to scale up, scaling back down again can require even more time than the former process, if doing so is even possible.
Storage -- Storage in on-premise environments is significantly more costly than Cloud-based storage, and was the principle reason that the philosophy of minimizing data within a physical warehouse was derived…… [Read More]
Generally, the classification of model transformation tools is based on whether it is declarative or operational, directionality or multiplicity.
The study further discusses the sub-categories of model transformation that include:
hybrid transformation tools, graph transformation, relational, template based, operational based, structure driven and direct manipulation.
All the sub-categories of model transformation have the following features:
Hybrid transformation combines two or more transformation approaches;
Graph transformation focuses on graph rewriting over variation and extensions of labeled graphs.
Relational approach uses declarative approach-based mathematical relations; template approach uses model template specifications.
