  Tutorial: Automatically implement design guidelines in your code

Design guidelines represent mere intent; for success however, implementing these guidelines is essential. The traditional way of implementing them is via code reviews.

Tutorial Details:

Hammurapi, a design-compliance tool, provides an automated and consistent way of implementing design guidelines, thereby making design reviews effective and painless. In this tutorial, author Sidharth Sankar introduces Hammurapi, compares it with similar tools, and gives a quick peek under the hood to illustrate how it works.

As a J2EE architect, I\'m required to deliver detailed designs to project teams. Along with the UML (Unified Modeling Language) model, I also deliver design guidelines that capture best practices. For example, in Struts applications, I recommend avoiding instance variables in Action classes because Action classes are singletons, and the potential for multiple threads simultaneously executing an Action class instance is very real. As another example, in any DAO (Data Access Object) application, an important design guideline is to close all open database resources. Failure to do so is always disastrous?especially in a production environment.
