The Business Information Model, aka Conceptual Schema or Conceptual Data Model, consists of Business Entities, which represent key informational concepts with which the business people work to perform their jobs, the relationships among the Business Entities, and the business policies and rules that constrain the entities and their relationships.
The Business Information Model shows the pieces of information (Business Entities) that the business people use. It represents an enhanced glossary in that, not only does it unambiguously identify and provide definitions of the Business Entities, it also provides the relationships among them. The Business Information Model is a good source for finding business rules and entity based services in a service oriented architecture.
Business Policies
The Business Information model can include Business Policies, i.e. sets of related Business Rules that describe the conditions that must be obeyed to ensure the state of the Business Entities is valid. Policies and rules can govern the state of one or more Business Entities or the relationship among them.
Relationship Constraints
Constraints can be placed directly on the associations between Business Entities. To do so, open the association's properties dialog and click on the Constraints tab.
