Data model:

A data model is a logical representation of a database. The structure of a data model includes the relationship, content, and constraints that determine how the data can be stored and accessed. The data model is transformed into a database design.

The data model can be divided into three types:

  • Object based data model.
  • Physical data model.
  • Record based data model.
