What is Relational Database?
A relational database is based on the principle of relation and relation can be anything.
For example, there can be a relation between rows and columns or there can be a relation between tables.
Relational database follows the principle of RDBMS. RDBMS is a relational database management system.
DB2 also follows this particular principle:
DB2 is a product of IBM and most of the time it runs on IBM mainframes. we use this in assembly language that is AS400 Or runs in Linux environment.
We can go to Wikipedia and see details about IBM DB2.
The Developer of DB2 is IBM. It was released in 1983 initially and it is a type of RDBMS.
For example, we have currently supported platform history and so on.
