DB2 means database 2 or say database version 2. E.F Codd firstly decided to name RDBMS as db2.

DB2 is an early implementation of the relational database model developed by E.F. Codd at IBM. Codd introduced the relational model in the 1970s, and DB2 was IBM's commercial implementation of this model, launched in the early 1980s.

It is one of the first relational database management systems (RDBMS) that adhered to Codd's principles, including the use of Structured Query Language (SQL) for managing and retrieving data.
