Editing IBM System Object Model (section)

==Applications==

SOM was intended to be used universally in IBM's [[Mainframe computer|mainframe]] and desktop ([[OS/2]]) computers, allowing programs designed for the desktop to use a mainframe for processing and data storage. IBM produced versions of SOM/DSOM for OS/2, [[Microsoft Windows]] and various [[Unix]] flavors (notably IBM's own [[AIX operating system|AIX]]). For some time after the formation of the [[AIM alliance]], SOM/DSOM was also used by [[Apple Computer]] for similar purposes. It was most widely used in their [[OpenDoc]] framework, but saw limited use in other roles as well.

Perhaps the most widespread uses of SOM within IBM were in later versions of OS/2, which used it for most code, including the [[Workplace Shell]]. [[Object REXX]] for OS/2 is able to deal with SOM classes and objects including WPS.<ref>[http://www.edm2.com/index.php/SOM_and_Object_REXX SOM and Object REXX] by Dr. Willis Boughton (August 2004)</ref>

SOMobjects were not completely shut down by IBM. They were ported to OS/390, and are still available on this OS. One can read documentation on IBM website.<ref>{{Cite web|url=http://www-03.ibm.com/systems/z/os/zos/library/bkserv/os390_r10pdf/#som|archive-url=https://web.archive.org/web/20140106003410/http://www-03.ibm.com/systems/z/os/zos/library/bkserv/os390_r10pdf/#som|url-status=dead|archive-date=January 6, 2014|title=SOMobjects for OS/390 documentation}}</ref> In 1996 Tandem Computers Inc. obtained SOMobjects technology.<ref>{{Cite web |url=http://www.thefreelibrary.com/Tandem+Delivers+Enterprise+Transaction+Processing+Capabilities+to...-a018607143 |title=Tandem Leverages IBM's SOMobjects Technology for Distributed Object Computing |access-date=2015-05-02 |archive-date=2016-03-05 |archive-url=https://web.archive.org/web/20160305105046/http://www.thefreelibrary.com/Tandem+Delivers+Enterprise+Transaction+Processing+Capabilities+to...-a018607143 |url-status=dead }}</ref> Tandem was sold to Compaq, Compaq was sold to Hewlett-Packard. NonStop DOM and some other technologies eventually merged into NonStop CORBA, but current documentation of NonStop products does not contain signs of SOM technology still powering NonStop products.
