Answer:

Data modeling occurs at three levels—physical, logical, and conceptual.

  • A physical model is a schema or framework for how data is physically stored in a database.

  • A conceptual model identifies the high-level, user view of data.

  • A logical data model sits between the physical and conceptual levels and allows for the logical representation of data to be separate from its physical storage.

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.
