1.1. A Brief History of DB2
Since the 1970s, when IBM Research invented the Relational Model and the Structured Query Language (SQL), IBM has developed a complete family of RDBMS software. Development started on mainframe platforms such as Virtual Machine (VM), Virtual Storage Extended (VSE), and Multiple Virtual Storage (MVS). In 1983, DB2 for MVS Version 1 was born. "DB2" was used to indicate a shift from hierarchical databaseslike the Information Management System (IMS) popular at the timeto the new relational databases. DB2 development continued on mainframe platforms as well as on distributed platforms.[1] Figure 1.1 shows some of the highlights of DB2 history.[1] Distributed platforms, also referred to as open system platforms , include all platforms other than mainframe or midrange operating systems. Some examples are Linux, UNIX, and Windows.
