SB/XA is a 4GL development and runtime environment originally written for the Pick family of computer databases/environments and now part of the Rocket U2 software suite.
System Builder originally owned by Computermatic PL was started in a garden shed in South Africa by first cousins Neill and Derek Miller in 1982.
Traditionally, up to this time, Pick systems were accessed using green-screen terminals like the Wyse60 or VT100 but with the rise of the PC a new paradigm presented itself and so around the end of 1991 the product was enhanced with the addition of a specialised terminal emulation client called Termulator!
Shortly after, the client program was renamed SBClient and the ability to develop and render screens in either character or GUI mode.
On 1 October 2009, Rocket Software announced[1] the purchase of the entire U2 suite, which includes SystemBuilder, from IBM.
