Database Management Systems
What are the levels of data within a database and how are they used?
Microsoft's online tutorials clearly define the levels of data within a database, explaining how each are used in managing data, creating applications and designing taxonomies for managing complex data sets. The most fundamental component or element in a database is defined by Microsoft as an object. Microsoft's tutorials show how objects can be organized into data structures and tables. The foundational aspect of any database application is the development of data structures that can quickly be integrated together and defined from a contextual intelligence and workflow standpoint (Post, Kagan, 2001).
After going through the entire series of tutorials it is also very clear how queries are used for getting reports completed and applications also developed. Microsoft uses an extensive...
The use of database queries and elements is dependent on the properties of attributes and their definition of relative values within the context of application development and use (Post, Kagan, 2001). Microsoft differentiates database structural components from programming logic by concentrating queries, forms and reports in the latter tutorials. These are used for showing how the entire programming architecture of a database functions. Microsoft has provided a unique series of tutorials that illustrate how each aspect of database development and programming integrate together to create a platform for future application development.
What levels do you recognize from the tutorials and how are they used?
From our coursework I recognized all the ones mentioned, as Microsoft…

By grouping related database queries into transactions, DBMS systems can guarantee that each transaction satisfies the ACID properties: Atomicity, Consistency, Isolation, and Durability. However, if a database application is decomposed into transactions in an incorrect manner, the application may fail when executed concurrently. Concurrency control deals with the issues involved with allowing multiple people simultaneous access to shared entities (Ambler, 2004). A collision occurs when two activities, which may or
Hence, along with database security, it is important that the operating system is also secured from unauthorized access. Data Security Policy There are instances when not all information in a database is open for access to a user. Hence, there is the data security policy that controls the level of access a user has. According to Oracle Corporation Online, Data security includes the mechanisms that control the access and use of the
Another factor in open source database vendors leading this area is the focus on multiple models for scalability as can be seen in Table 1: DBMS Features Analysis. The support of multiple models of scalability also concentrates on OLTP transaction integration specifically within roles as defined in the security model (Pereira, Muppavarapu, Chung, 2006). Security will be discussed later in this analysis. The second factor used to evaluate closed source
management system (DBMS) is a program that provides the user with access to the data and also helps them in transforming their raw data into meaningful information. The database management system (DBMS) is therefore a collection of programs that helps in the management of data structure as well as in the control of access to the data that is stored in the database. The DBMS systems help users in
It was then important to see the degree at which technology and training played a role in combating each fire. 1.2.4.Rationale of the Study What is that can be gained from this study? The reasoning behind such a study is born out of a need to provide better training for fire fighters so that fire management systems will improve and reduce the amount of loss due to the fire. By studying
Enterprise DBMS 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
