The description of these Objects is a [[Schema]].

As an example, in a Payroll System, a Company is an Object. An Employee is another Object. Employment is a Relationship or Association. An Employee Class (or Object for simplicity) has Attributes like Name, Birthdate, etc. The Association itself may be considered as an Object, having Attributes, or Qualifiers like Position, etc. An Employee Method may be PomotePromote, Raise, etc.

The Model description or [[Schema]] may grow in complexity to require a Notation. Many notations has been proposed, based on different paradigms, diverged, and converged in a more popular one known as [[Unified Modeling Language|UML]].
