DB2

IBM DB2 (DB2 LUW, DB2 z/OS, DB2 for i, DB2 AS/400, DB2 iSeries)

IBM DB2 database has a long history and is available on a myriad of IBM mainframes and operating systems. Its original roots are in 70s, when IBM’s researcher Edgar F. Codd described the theory of relational databases and relational algebra. However, DB2 (or IBM Database 2) name was officially assigned to a product in 1983. IBM, ironically, failed to recognize the potential of Codd’s innovation and Oracle ended up actually beating IBM to market with its SQL language implementation.

Today, IBM DB2 is still going strong and is capable of supporting legacy (read - extremely old) applications, as well as providing latest features. It is very reliable and fast database, used in enterprise market. TPC-C and TPC-H industry benchmarks show excellent performance of DB2.

Competing with Oracle, DB2 is supposedly able to run 98% of Oracle SQL code without changes, allowing even very large codebases to migrate from Oracle to DB2 relatively quickly. DB2 is able to reach great performance levels.

It is believed that most of world's data still resides on IBM DB2 mainframes.

Even though they all share DB2 name, DB2 variants (DB2 Linux/Unix/Windows, DB2 for z/OS, and DB2 for i) are actually completely different databases. Full Convert Pro and Ultimate support all of them.
