System Object Model: Difference between revisions

Latest revision as of 15:53, 7 April 2024

System Object Model (SOM) is an object-oriented shared library system. DSOM, a distributed version based on CORBA, allowed objects on different computers to communicate. System Object Model (SOM, SOMObjects) is a language neutral object model.
