Introduce The Patterns Into Audit Software Design With The Refactoring

Software need to modify continually in order to adapt the new environment andnew requirement of user. During the modification, the developers will add code intothe software, and the software becomes so complex result in the maintainabilitydecline.Design Patterns as common ways to deal with the object-oriented problem hadbeen used in system analyses and design. Design Patterns provide some reusable andflexible solutions to raise the maintainability of software code.The method of refactoring is to improve the design of existing code andrestructure software by applying a series of refactorings without changing itsobservable behavior. Refactoring modify the code piece by piece, and emphasize thattest is first so that the code is so robust and easy to maintain.Our research based on one of project of Golden Audit Project—audit statisticmanagement software. Major jobs are:1. Introduce design pattern for improving existing design to raise flexible;2. Use refactoring way to sure system expansibility;3. Apply multi-patterns into a process.During the software update, with advantage of refactoring, introduce graduallydesign patterns to make it better according to the user requirements. And the designcan Shake off the dependence for the platform and development language. As designsare described with UML, the software analysis model will be formed that is to base onthe audit field in the future.
