Answer to Question 1

Business rules are policies that constrain data values and the processing of the database. These policies represent business decisions and directives. The development team identifies and documents business rules during the creation of the data model. Often, these business rules are too specific or complex to be addressed by the database design directly. Therefore, the business rules are typically documented with the database design so that they can be enforced through procedural logic and application programs.

Answer to Question 2

Michael Porter includes four business activities in his definition of support activities. These include:
 Procurement: managing supplier relationships and buying the product inputs.
 Technology management: product research and development and new procedures, methods and techniques.
 Human resources management: managing employee resources.
 Firm infrastructure management: general management of the firm, finance, accounting, legal services, and government affairs.
