The term object model can be used in two different contexts. In one sense; it refers to a collection of concepts used to describe the generic characteristics of objects particularly object oriented languages or its specifications. Over here it closely corresponds to the word data model. Examples of this can be Java object model. This contrasts with the object model used to describe collection of object classes used to model a particular system. A common application of this object model can be defined as the Document Object Model
Any object model has three key concepts
- data structures that can be used to represent the object state
- ways to associate behaviour with the object state
- ways for the object methods to access and operate on that state
