Explore data models in DBMS with types, features, and tools. Learn how proper data modeling ensures accurate, efficient, and well-structured databases. Data models describe how a database’s logical structure is represented. 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. Data Models in DBMS The Data Model is defined as an abstract model that organizes data description, data semantics, and consistency constraints of data.

Data Model is like an architect’s building plan, which helps to build conceptual models and set a relationship between data items. The two types of Data Modeling Techniques are Entity Relationship (E-R ... Data Models are fundamental entities to introduce abstraction in a DBMS. Data models define how data is connected to each other and how they are processed and stored inside the system.
