What Does Db2 (DB/2) Mean?
Db2 is a line of data management products from IBM. It includes a well-known relational database management system (RDMS) that IBM introduced in 1983 to run on its MVS (Multiple Virtual Storage) mainframe platform. The name DB/2 originally referred to IBM's shift from a hierarchical database model to the relational database model. IBM rebranded the line of database products Db2 in 2017.
Although DB2 was initially designed to work exclusively on IBM mainframe platforms, it was later ported to other widely used operating systems, including UNIX, Windows and Linux and now supports non-relational structures such as JSON and XML. Today, Db2 plays an integral part of IBM’s information management portfolio both locally and in the cloud, making it possible for organizations of varying sizes to handle large quantities of data and serve large number of users concurrently.
