Role of a DBMS: serves as the intermediary between the user and the database, storing collection(s) of files; receives all application requests request and translates them into the complex operations required to fulfill those requests. Properly written rules are used to define entities attributes relationships, and constraints. Begin by sketching the contour. The DDLs use enabled the database administrator to define the database schema, i.e., its over all blueprint. Therefore, a category rules must be widely distributed and easy to understand. 3. These business rules are then translated into data structures to formulate a concrete database design. 1. Data Model structure helps to define the relational tables, primary and foreign keys and stored procedures. A relationship describes an association among entities. Relational model is a based on mathematical set theory and represents data as independent relations. Its conceptual simplicity set the stage for a genuine database revolution for both end user and designer.
