DB2 is IBM's family of information management software products. Most often, though, when people say DB2 they are referring to IBM's flagship relational database management system, DB2 Universal Database (DB2 UDB).
History
DB2 has a long history and was what some consider to be the first database product to use SQL.
The name DB2 was first given to the Database Management System or DBMS in 1982 where IBM released SQL/DS and DB2 on its mainframe platform. Prior to this the product was named System Relational, or System R, which launched in 1978. DB2 has its roots back to the beginning of the seventies where Dr. E.F. Codd, working for IBM, described the theory of relational databases and in June of 1970 published the model for data manipulation. To apply the model Codd needed a relational database language which he named Alpha. IBM didn't believe in Codd's idea's potential, leaving its implementation to a group of programmers who weren't under Codd's supervision, violating several fundamentals of the relational model; the result was Structured English QUEry Language or SEQUEL. SEQUEL was already a trademarked name, so IBM renamed the acronym to SQL, short for Structured Query Language. The acronym SQL still stands to this day.
Historically, it is interesting to note that when Informix acquired Illustra and made their database engine an object-SQL DBMS by introducing their Universal Server, both Oracle and IBM followed suit by changing their database engines to be capable of object-relational extensions. Moreover, in 2001, IBM bought Informix and in the following years incorporated Informix technology into the DB2 product suite. Technically, today, DB2 can be considered to be an object-SQL DBMS.
