Types of Databases
Based on the type of database in which the data will be stored, managed, and manipulated, there are three types of databases.
- Network database
- Classification database
- Relational database
1 – Classification database
This type of database uses a tree structure to store data. Just as a tree has many branches, data is stored in a Hierarchical Database based on the same principle. For example, take the example of different children studying in a school in which the children have different subjects and classes.
It has a school tree and the children studying in the school are the branches of this tree. All the nodes in it are interconnected by links. It is the oldest database model developed by IBM in 1960.
2 – Network database
The network database model is a powerful database, but it is also a bit complex because all the tables in it are linked to each other. This database model for storing data Network The structure is therefore called a network database.
3 – Relational database
In this type of database, data is arranged in a table in the form of rows and columns, it is a very simple database model that is widely used nowadays. Any user can use this database with a little training. Just like Excel or Google When you create a sheet, it is a relational database model.
A database has 3 elements.

- Loss of data on paper.
- Loss of paper
- Any typos
- It’s taking too much time
- More staff is needed to manage the data.
- Rats bite on papers etc.
To overcome all these shortcomings a computer database was needed, which should not have all the above problems. With the advancement of technology, we started storing data in computers and servers by creating databases in the form of files instead of papers, and today computerized databases are used in almost all fields.
