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. 1. If you want to design a data storage system that makes it easy to manage lots of information, and is scalable and flexible, the relational database is a good bet. 3.

The building blocks of the relational model has been developed on the concept of mathematical relation. 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. Reduced data storage footprint, i.e. These connections allow you to create links between meaningful information by joining tables together.
