What are "business rules" and what is their role in database design?
What will be an ideal response?
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.
