| 释义 |
SystemBuilder is the name of 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. The SystemBuilder environment comprises SB+ Server, often running on a Rocket U2 database, and SBClient which runs as a Microsoft Windows desktop application. The product can be run in either developer or runtime mode. The development environment enables rapid prototyping, development and deployment of applications and includes a rudimentary GUI application environment. HistorySystem Builder was started in a garden shed in South Africa by first cousins Neill and Derek Miller in 1982. The popularity of the Pick database system, combined with a lack of a good development framework led them to develop a tool to build standard menus and screens.{{cn|date=July 2018}} The System Builder Software company was incorporated in the Isle of Man when the cousins moved to Sydney, Australia in the early 1980s. The product was very successful and after expanding into international markets and after a few versions they began to re-develop the product from the ground up. This was to become SB+ and was released in early 1990. Traditionally, up to this time, Pick systems were accessed using dumb green-screen terminals 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!. This was able to tightly integrate the server and the PC to allow for facilities like downloads direct from the server into Lotus 1-2-3 or the new kid on the block, Microsoft Excel. Shortly after, the client program was renamed SBClient and the ability to render the server 'green-screens' as client GUI screens was added with a clever set of driver interpreters. Having been bought by Unidata Corporation in 1996, and following Unidata's merger with VMark Software to form Ardent Software in 1998, the SystemBuilder product set came under the ownership of Informix in 2000 following their purchase of Ardent Software for its Datastage product. Subsequently, in 2001 Informix themselves were bought by IBM, and the U2 and SystemBuilder products eventually found their way to become part of IBM's Data Management portfolio. Development of the SystemBuilder and RedBack products continued in Sydney until 2005, when they were merged with the U2 development team located in Denver, United States. More recently, on 1 October 2009, Rocket Software announced[1] the purchase of the entire U2 suite, which includes SystemBuilder, from IBM. The SystemBuilder Development EnvironmentThe System Builder/SB+ server environment is based around a set of key tools and utilities. These leverage out to provide a powerful{{cn|date=July 2018}} and comprehensive{{cn|date=July 2018}} development environment which is, itself, built mainly from these tools. SB+ includes an application menuing system, screen generator, a 3GL programming language, an expression language, the GUI components and report writer tool. EvolutionThe most recent iteration of System Builder is SB/XA (v6.5.2) released in Oct 2017 - SB/XA includes many major enhancements including a new GUI system based on XAML. [2]External links
