Research and application of design patterns on shopping mall component design

Software reusability is always the goal for the software people. It can improve the productivity and quality of software. Software architecture, design patterns, framework and components are the bases of application software reuse. Design patterns impenetrate into the whole process of software reuse, which is the important experience reference from software architecture to framework, form domain model to components. There are different domain models and frameworks in different domains. Referred to the shopping mall domain, the method of component design is introduced that domain model and framework can be obtained by domain analysis and then the design of components that are extracted from domain model could implement optimization to gain good system framework by the use of Strategy Pattern, Bridge Pattern and Abstract Factory Pattern.
