A DBMS acts as a conduit between the database and the applications that will use it, enabling users to access, modify, and control how the data is arranged and optimized.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of relational databases. Data items are requested from the database by application programs, which are created using a combination of the DBMS's data manipulation language and a traditional programming language. The DBMS locates and provides the data elements requested by the application programs.
