Db2 is a family of data management products, including database servers, developed by IBM. It initially supported the relational model, but was extended to support object–relational features and non-relational structures like JSON and XML. The brand name was originally styled as DB2[3][4][5] until 2017,[6] when it changed to its present form. (In the early days, it was sometimes wrongly styled as DB/2 - in a false derivation from the operating system OS/2 [7].)
