what are the benefits of relational database model?

Each table of data can be updated without disrupting the others.You can also share certain sets of data with one group, but limit their access to others – such as confidential information about employees.

Relational databases has many advantages but amongst the disadvantages are * They tend to be slow and not scalable. The relational data model is employed for storing and processingthe data in the database.

In simple terms, they support end user rights and create privilege, select and insert rights, which allow users to make corresponding operations or modifications on the database. This advanced, more efficient version of the traditional database management system can store data in rows and columns (or tuples and attributes, respectively) and accessed using a database query language like SQL .

The self-driving database (also known as the autonomous database ) maintains the power and advantages of the relational model but uses artificial intelligence (AI), machine learning, and automation to monitor and improve query performance and management … To continue the previous example, if only one test grade is being organised along with contact information, only one table will be needed. Supports set functions The data is linked by a certain code that appears in both tables under the same person's information. Another benefit of using a relational database is efficiency.
