A data model in DBMS serves as a blueprint for how data is organized and structured within a database. It defines the entities, their attributes, and the relationships between them. Acting as a conceptual representation, it ensures clarity and consistency in database design. Different types of data models exist, such as hierarchical, network, relational, and entity-relationship (ER), each with its own way of structuring data and defining connections. The choice of data model significantly impacts how data is stored, accessed, and managed within the database system https://www.tpointtech.com/data-models
