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 used for….

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. (Prakash, 2010)

The formats mentioned her by Prakash (2010) are fundamentally responsive to a new form of data storage and formatting, where objects are saved….

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, standard-relational databases….

Database Concepts
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 design and implementation may….


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 database these….

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 that a client….

Oracle supports stored programs such as stored procedures and packages. This enables the developers to centralize application logic in the database. Oracle provides powerful functions and sub-queries in its SQL statements. Developers can distribute systems by database links, materialized views and distributed queries. This feature saves much cost for developing distributed systems and applications. And there's a lot of features integrated with Oracle, compare to other database it is very expensive but it is extremely powerful and fast.

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….

Databases
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 (Chu,….

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
until 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 that is always aborted….

Database Software
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 to as….
