Data models in dbms: Data Models are fundamental entities to introduce

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. Explore different data models in DBMS, including relational, hierarchical, XML, Network and NoSQL models, with comparisons, advantages, and real-world use cases 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 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.
