These pages are based on several books: Gamma et al, Design Patterns: Elements of Reuse in Object Oriented Software; Buschmann et al, A System of Patterns; Pree, Design Patterns for Object-OrientedSoftware Development; and Coplien and Schmidt, Pattern Languages for Program Design. This is meant to be used as a quick tutorial on design patterns.

A design pattern describes a proven solution to a recurring design problem, placing particular emphasis on the context and forces surrounding the problem, and the consequences and impact of the solution.

This website provides a palette of patterns you can use in the context of designing J2EE applications with the Java Enterprise BluePrints. Every now and then, new patterns will be added and new insights will be incorporated into the current patterns, so check back often for updates.

This section describes the Model-View-Controller (MVC) architecture, which provides the backdrop for many J2EE design patterns.

According to their site, the Hillside Group is "a nonprofit corporation dedicated to improving human communication about computers by encouraging people to codify common programming and design practice." They host conferences on patterns and the home page for the patterns community.

We're writing about computer programs in a new stylistic form called pattern languages. The form has many internal references which map well to hypertext links. We've added links to published (or soon to be published) documents.

This repository is maintained by Ward Cunningham, who, along with his colleague Kent Beck, was one of the pioneers of the software patterns movement.

The original reference site for patterns. Frequented by the gang of 4 and their mentors (Kent Beck, Ward Cunningham).

The J2EE Patterns presented here, a collection of J2EE-based solutions to common problems, reflect the collective expertise and experience of Java technology architects in the Sun Java Center over the past three years.

Patterns for e-business are a group of reusable assets that can help speed the process of developing Web-based applications. This site breaks down these reusable assets into the following elements:

• Business patterns identify the interaction between users, businesses, and data. Business patterns are used to create simple, end-to-end e-business applications.
• Integration patterns connect other Business patterns together to create applications with advanced functionality. Integration patterns are used to combine Business patterns in advanced e-business applications.
• Composite patterns are combinations of Business patterns and Integration patterns that have themselves become commonly used types of e-business applications. Composite patterns are advanced e-business applications.
• Custom designs are similar to Composite patterns, as they combine Business patterns and Integration patterns to form an advanced, end-to-end solution. These solutions, however, have not been implemented to the extent of Composite patterns, but are instead developed to solve the e-business problems of one specific company, or perhaps several enterprises with similar problems.
• Application and Runtime patterns are driven by the customer's requirements and describe the shape of applications and the supporting runtime needed to build the e-business application.
• Product mappings to populate the solution. The product mappings are based on proven implementations.
• Guidelines for the design, development, deployment, and management of e-business applications.

The Patterns leverage the experience of IBM architects to create solutions quickly, whether for a small local business or a large multinational enterprise. As shown in the following figure, customer requirements are quickly translated through the different levels of Patterns assets to identify a final solution design and product mapping appropriate for the application being developed.
