Types of Database Management System

● Network Model: - In this type of database management system, the data model forms a graph. Here, the graph can be accessed via numerous paths. To address many-to-many relationships between attributes, a network model appears. For example- many parents have many children.
● Relational Model: - This DBMS model is widely used. Because it follows a stranded way approach. In this data model, the data is normalized with the latest update where all rows and columns of the tables are stores in a well-structured format.
● Object-Oriented Model: - In this model, data are stored in the form of objects. The structure used here is called classes. It shows data within the class.
