Explore data models in DBMS with types, features, and tools. Learn how proper data modeling ensures accurate, efficient, and well-structured databases. Data modeling (data modelling) is the process of creating a data model for the data to be stored in a database. This data model is a conceptual representation of Data objects, the associations between different data objects, and the rules. Data Models in DBMS The Data Model is defined as an abstract model that organizes data description, data semantics, and consistency constraints of data.

In a database management system, data models are essential for introducing abstraction. Data models specify how data is linked to one another, as well as how it is handled and stored within the system.
