Static Models Object Attributes and Invariants

Chapter 2, Static Models Object Attributes and Invariants, describes how attributes abstract variations in the implementation of object state. Chapter 3, Behavior Models Object Types and Operations, describes how operation specifications describe externally visible behavior of an object, independently of algorithmic and representation decisions. 

The static part deals with the information we have about the state of an object at ary given moment. At a given level of time granularity, we describe static attributes, relationships, and constraints between objects. Chapter 2, Static Models Object Attributes and Invariants, is about modeling static aspects using abstract attributes.
