ObjectModel

Last edit July 7, 2014

What is an Object Model?

the physical layout of objects in memory. E.g. the the COM ObjectModel, the JVM ObjectModel.
the nature of objects in a programming language (including everything objects inherit from Object). E.g. the Java ObjectModel or the Smalltalk ObjectModel.
a kind of diagram, or an incarnation of that kind of diagram. E.g. the UnifiedModelingLanguage ObjectModel diagram or the ObjectModel of an application domain.
a specific configuration of objects at runtime. E.g. if you program in JavaScript you have different ObjectModel-s in NetscapeNavigator and InternetExplorer.
The OMT methodology uses the term "object model" to refer the class diagrams (and instance diagrams) used to describe part or all of a system.
