What Not how: The Business Rules Approach to Application Development

Front Cover
Addison-Wesley Professional, 2000 - Business & Economics - 131 pages

"What I think Date has done is nothing less than to lay out the foundational concepts for the next generation of business logic servers based on predicate logic. Such a breakthrough should revolutionize application development in our industry--and take business rules to their fullest expression."
--Ronald G. Ross, Principal, Business Rule Solutions, LLC

The way we build computer applications is about to change dramatically, thanks to a new development technology known as business rules. The key idea behind the technology is that we can build applications declaratively instead of procedurally--that is, we can simply state WHAT needs to be done instead of HOW to do what needs to be done. The advantages are obvious: ease and rapidity of initial development and subsequent maintenance, hardware and software platform independence, overall productivity, business adaptivity, and more.

What Not How: The Business Rules Approach to Application Development is a concise and accessible introduction to this new technology. It is written for both managers and technical professionals. The book consists of two parts: Part I presents a broad overview of what business rules are all about; Part II then revisits the ideas in Part I and shows how they fit squarely into the solid tradition of relational technology. Topics covered include:

  • Presentation rules
  • Database and application rules
  • Building on the data model
  • Potential advantages and disadvantages
  • A new look at relational fundamentals
  • Business rules and the relational model

Overall, the book provides a good grounding in an important new technology, one poised to transform the way we do business in the IT world.

Never imagined a company-sponsored book could be so good. Argues that business rules belong in a relational database, in the form of declarative integrity constraints. Read full review
