Details

Donald Haderle is an American computer scientist and IBM Fellow, best known for his work on relational database management systems (RDBMS). He led the architecture and design of DB2, one of the first commercial RDBMSs, which led to his moniker "Father of DB2." DB2 debuted on IBM's mainframe system MVS in 1983 and validated the applicability of relational databases for high performance transaction processing. With DB2 enterprises store, retrieve, and analyze their business transaction data. The cited reference describes the early technology hurdles, the shift from a monolithic architecture to a distributed architecture portable across many operating systems (Unix, Windows, OS/2, and others) and the technology collaborations with IBM Research. DB2 is used in most enterprises around the world.
