What is the advantage of relational database

Easy to understand and use: The structure of Relational DB is very simple. There are different rows and columns in the table, which makes it easy to manage the data. SQL is used to access it, which is very easy.

It reduces data redundancy: In relational database management system, each table has specific data and data can be accessed by linking different tables if needed. This does not cause the problem of duplicate data.

Data Security: In a relational database management system, the database administrator has the authority to grant data access to certain users which makes the data secure. A password is required to access it.

It is flexible: In this database model we can easily increase its size by creating as many tables as we want and can link these tables among themselves
