【摘要】 系统分析和设计在企业管理信息系统构建中的重要作用勿庸置疑。面向对象系统分析和设计则在学术界和实业界得到了广泛的认同和实践尝试。应用面向对象系统分析和设计于企业管理信息系统,显然具有重要而现实的意义。 不过,面向对象系统分析和设计在企业信息系统构建中的应用并不理想,因为传统的结构化分析和设计与面向对象系统分析和设计相比,有其不可替代的优势。所以,需要将两者结合起来,取长补短,解决系统分析和设计中的困难。作者认为,面向对象系统分析方法和设计方法有很大的优越性,可是,在面对复杂系统时,要解决系统中的困难,需要一个过程来指导系统分析和设计活动,结合应用优秀的系统分析和设计方法。另外,分析和设计过程和分析设计方法是相辅相成的,两者的合理结合才能解决系统日益复杂的问题。 本文在阐述了这一现象后,通过对系统分析和设计、面向对象系统分析和设计发展过程的细致分析,提出了一个系统分析和设计过程:采用一种成熟合理的系统架构,结合运用面向对象系统分析的重要概念——用例,并且在过程中应用被广泛接受的面向对象系统分析和设计方法、思想来解决系统分析和设计的问题。并通过实例来说明。最后,结合目前信息技术发展的趋势,提出了对信息系统分析和设计这一领域发展的展望。 另外,面向对象的系统分析和设计方法已经有了一个事实上的表示工具标准——UML,而且已经得到了较广泛的认同。在实例中,作者结合实例特点,在分析和设计中,对应用这种重要的表示工具,结合面向对象的思想,提出了一些应用中的创新。
【Abstract】 System analysis and design plays an important role in constructing information system. Object oriented analysis and design,on the other hand,is widely accepted by academia and industry. Applying objected oriented analysis and design to construction of MIS has an important and realistic significance.In reality,the trend hasn’t been propitious,as traditional structural analysis and design has an obvious advantage over object-oriented analysis and design. The best way is to integrate these two means. The thesis concludes that on dealing with the complexity of the real system,it’s important to provide a procedure of analysis and design. We can perform analysis and design according to the procedure and employ different means. What’s more,procedure and means associate with each other tightly and influence one another. To combine the procedure and means of analysis and design smartly is the only way to settle the problem of complexity.The thesis carefully analyzes the development of system analysis and design and proposes a procedure of analyzing and design information system. The procedure also makes an intensive use of widely accepted object- oriented means. The thesis achieved the goal by analyzing an important conception in object-oriented field - use case in a mature and reasonable framework. These have been further proved by a real example. Lastly,the thesis prospects the future of system analysis and design considering the recent development of information technology.Object oriented analysis and design has established a standard of expressing the results of analysis and design. It’s the graphic tools - UML. In the example,the thesis discusses the possibility of applying the UML in a reasonable way and a few new ideas of using the tools that have been proposed.
