Rocket U2 is a suite of database management (DBMS) and supporting software now owned by Rocket Software. It includes two MultiValue database platforms: UniData and UniVerse. Both of these products are operating environments which run on current Unix, Linux and Windows operating systems. They are both derivatives of the Pick operating system. The family also includes developer and web-enabling technologies including SystemBuilder/SB+, SB/XA, U2 Web Development Environment (WebDE), UniObjects and wIntegrate.

UniVerse was originally developed by VMark Software and UniData was originally developed by the Unidata Corporation. Both Universe and Unidata are used for vertical application development and are embedded into the vertical software applications. In 1997, the Unidata Corporation merged with VMark Systems to form Ardent Software. In March 2000, Ardent Software was acquired by Informix. IBM subsequently acquired the database division of Informix in April 2001, making UniVerse and UniData part of IBM's DB2 product family. IBM subsequently created the Information Management group of which Data Management is one of the sub-areas under which the IBM U2 family comprised UniData and UniVerse along with the tools, SystemBuilder Extensible Architecture (SB/XA), U2 Web Development Environment (U2 Web DE) and wIntegrate.

On 1 October 2009 it was announced that Rocket Software had purchased the entire U2 portfolio from IBM. The U2 portfolio is grouped under the name RocketU2.

Systems are made of one or more accounts. Accounts are directories stored on the host operating system that initially contain the set of files needed for the system to function properly. This includes the system's VOC (vocabulary) file that contains every command, filename, keyword, alias, script, and other pointers. Each of these classes of VOC entries can also be created by a user.
