Do The DBMS reveal much of the databases internal complexity to the application programs and users?
From Database Systems: Design, Implementation, and Management 10th Ed - Coronel / Morris / Rob - 1.3.1 Role and Advantages of the DBMS: The DBMS serves as the intermediary between the user and the database. The database structure itself is stored as a collection of files, and the only way to access the data in those files is through the DBMS. Figure 1.2 emphasizes the point that the DBMS presents the end user (or application program) with a single, integrated view of the data in the database. The DBMS receives all application requests and translates them into the complex operations required to fulfill those requests. The DBMS hides much of the database's internal complexity from the application programs and users. The application program might be written by a programmer using a programming language such as Visual Basic.NET, Java, or C#, or it might be created through a DBMS utility program.
