There are different types of Database models and each one has its own set of features

×A data model in database management system (DBMS) is a tool that summarizes the description of the database. Data models provide a transparent picture of data which helps in creating an actual database. There are several types of database models, including:
  • Hierarchical Model: organizes data into a tree-like structure, with a single root, to which all the other data is linked.
  • Network Model: an extension of the Hierarchical model.
  • Entity-relationship Model: relationships are created by dividing object of interest into entity and its characteristics into attributes.
  • Relational Model: data is organized into one or more tables (or "relations") with a unique key identifying each row.
,A Data Model in Database Management System (DBMS) is the concept of tools that are developed to summarize the description of the database. Data Models provide us with a transparent picture of data which helps us in creating an actual database. It shows us from the design of the data to its proper implementation of data.Data models define how the logical structure of a database is modeled. 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.
