EDOC — Ch 3: p 196-197: The Entity model

2. Ch 3: p 196-197: The Entity model in the Information Viewpoint, like any primarily structural model, has its most valuable information in the static invariants across attributes of entities. When partitioned across components (page 197), these static invariants get transformed into protocols on connections between those components to maintain those invariants. Standard patterns of these invariants should be defined (using the Patterns Profile, Chapter 4), and standard transformation of those should be defined as well
