Research And Practice Of The Software Development Method Based On Design Pattern

The increasing scale and complexity of software challenges software development dramatically.Software reuse has been seen as a feasible means to solvethe software crisis and to improve both productivity and quality of the software. Component technology is one of the core technologies supporting reuse. Component-Based Development has been developing very fast yet has not redeemed its promise of reuse and flexibility. Comparatively, design pattern supports reuse at a higher level and is much more feasible in practice.Considers to based on J2EE technical B/S structure has the maintainability well, may the extension good, the security be good and so on the merit, selected some J2EE enterprise application design pattern to carry on the analysis, how has solved the pattern is has an effect, the pattern in the system should apply in what kind of scene, the pattern should how apply and so on the question. Further more, in based on the component development and above the design pattern system foundation, in the reference tradition software engineering software method of exploitation, proposed based on the design pattern software method of exploitation. In paper final, according to based on design pattern software method of exploitation, through a typical J2EE application example - "goods and material handling information system" the design and the realization, showed based on the design pattern software method of exploitation feasibility.
