Relational database

The today's topic of our class was Relational database. We have learnt that the database is a collection of interrelated data. And there 4 types of database models. There are such models as hierarchical database, network database, relational database and object-relational database.

Database Management System is a software system for manipulating databases and it has five primary functions: define, create and organize a data, input data, process data, maintain data integrity and security and query database.

It was our last class, so I wish to all of us good luck, we must do our best.
