The Research And Implement Of The Auto-Solution Oriented Software Patterns On The Web Reengineering

With the rapid development of Internet techniques, the web-centric computing is getting more and more popular. And many legacy systems based on traditional software architecture need to migrate to new web based systems. This kind of migrating process is named as web-centric reengineering.So-called legacy systems are normally large systems built in an era before encapsulation and componentization were regarded as fundamental tenets of design. Through a gradual process of accretion and change, they have become devoid of useful structure. This makes them hard, expensive or impossible to modify in order to meet changes in the business processes.Since the structure of legacy system is complex, the requirement of system immigration is different, the web-centric reengineering practice lacks the support of theory methodologies and standards, and Web support software techniques develop so rapidly that the developers cannot get all the experiences, so it is easy to get failed.In this paper, pass the concrete case developed by Beijing University Of Technology Software Engineering Institute, we introduce the idea of software reengineering patterns, which adapt the ideas of software patterns to identify lessons in successful reengineering projects and to make these lessons available to new projects.
