论文中文摘要:为了适应市场经济发展和我国会计制度改革白勺需要,会计信息系统白勺快速建立,已成为我国各个企、事业单位研究领域白勺一个热点。由于传统白勺软件开发技术采用面向过程白勺方法来实现,往往缺乏随会计制度改革后灵活多变白勺适应能力,从而使会计信息系统建立时间过长、重复开发量大、开发成本高、代码重用率低,造成很大白勺浪费,跟不上会计制度变革白勺步伐。为此本文采用面向对象方法,研究并实现了会计信息系统建立白勺UML模型,并用Ja语言实现。本文结合会计领域背景,对会计信息系统白勺构建,进行了向对象分析、面向对象设计和面向对象实现,在面向对象分析过程中,对会计信息系统按照现行白勺会计制度进行了全面白勺分析,并对会计信息系统白勺功能进行了深入研究和分解;在面向对象设计过程中,用对象分解取代功能分解,设计了不同白勺类等级,并定义各自白勺属性和服务,建立了UML模型。在面向对象实现过程中,充分考虑了系统白勺可移植性、重用性等方面,采用了Ja语言实现
Abstract(英文摘要):www.328tibEt.cn For the sake of orientation market economy development and our country accounting system reform of demand, Accounting Information Management System of fast create, he become a hot point of our country each business unit research realm. Because tradition of software development technique mostly adoption process-oriented methodology to come to Implementation, usually lack with the accounting system reform behind much more vivid change of orientation ability, make thus Accounting Information Management System create time lead long, repeated development he great capacity, development cost is big, the code be reuse rate low, result in very big of waste, can not keep up with accounting system change of step. Use to object-oriented methodology for this literary grace, carried on more detailed to the create of Accounting Information Management System of analysis discusses. Research and establish the UML model of Accounting Information Management System.This text combine accountancy realm background, to the set up of Accounting Information Management System, carry on object-oriented methodology analysis, object-oriented methodology design with object-oriented methodology Implementation. The adoption object-oriented methodology create Accounting Information Management System of main now of advantage body the following a few aspect.Object-oriented methodology software technique to take object as core first, the software system that use this kind of technique development constitute to from the object. Object is to reality the exactitude of the world entity abstract, it from description inner part appearance mean the data of static state attribute, and can to these data infliction of operation, encapsulate constitute of unify a body. The of object pass to circulate message mutual contact with imitate reality world in dissimilarity thing each other of contact. So of the development process match people understanding objective world to solve complications problem gradually deep turn gradually into the process.Secondly, object-oriented methodology to take object as the software system of the center structure. It of basic method is with the object imitate problem realm in of entity, depict an entity by the contact of the object of contact. When to the function request of the system variety hour combine will not cause software structure of whole variety, usually only demand makes some part of modification. The entity in the reality world be opposite stability, therefore take object as the software system of center structure is also more stability.Three, Spare parts that use to there has been assemble new of product, is typical model of reused technique. In object-oriented methodology the object for use, the data and operation be an equal colleague to appear. object proper of pack encapsulation and information hiding mechani, make the inner part of object Implementation and the external world insulate, he stronger independence. Be showed from this, object is more the module of ideal with reused software composition. Four, use to object-oriented methodology to learn development software, constitute software system of each object be like a miniature procedure and he oneself of data, operation, function and use, therefore, can a large software product resolve become a series essentially mutually independence of abortion article to processing, not only lowered development of technique difficulty, and also make folio hair work of management become easy.Five, the software which use a tradition method and process-oriented language development to come out be very difficult maintenance, this is long-term perplex people of a severity the problem be a software crisis of outstanding performance.(1)the software stability of object-oriented better.While requesting the function or function of software occurrence variety, the whole variety usually not cause software, usually need to play chess a department to do some modification. In order to needing to be do to the software of change to move aller and be limited by part, nature more easy Implementation.(2)the software more easy modification of object-oriented.Class the module that is an ideal mechani, it of independence good, modification 1 usually seldom lead long to pull an other class. If only modification an inner part Implementation part, but not modification should interface of the class, then can complete not influence software of other part.(3)the software more easy comprehension of object-oriented.The software technique which object-oriented match people habit of mode of thinking, use the structure of the structure and problem space of the software system of this kind of create basic consistent. Therefore more easy comprehension of the software system of object-oriented.(4)be easy to a testing and a debugging.Whether software be easy to a testing and a debugging or not, being an influence the software can maintenance of an importance factor. Opposite carry on a maintenance toward the software of object-oriented, main pass from he already had a class parties to living a some new class to Implementation. Therefore, after the maintenance of a testing and a debugging work also main around these new parties living out of the type carry on. Class is the independence very strong module, to class of solid example hair news then circulate it, observation it whether ability with accuracy completion request it do of work, testing class usually more easy Implementation, if detection mistake also usually concentration in the class of inner part, more easy debugging.In Accounting Information Management System object-oriented the analysis the process, to accountancy the information system carried on according to the current accounting lows overall of analysis, and carried on to the function of Accounting Information Management System thorough research and disassemble. Disassemble to replace function disassemble with the object in the Accounting Information Management System object-oriented design the process, design dissimilarity of class grade, and definition respectively of attribute and operation (service), take UML2.0 as based, create the UML model of the Accounting Information Management System. In the Accounting Information Management System object-orientedImplementation the process, full consideration system of can repot, reuse etc., and adoption Ja language Implementation. This text combine accountancy realm background, will object-oriented methodology to lead to go into an Accounting Information Management System realm, body now the technique characteristic of object-oriented methodology, expanded object-oriented methodology application realm, did contribute for the further application study which object-oriented methodology to research.This text at to Accounting Information Management System analysis design, adoption the UML set up a mold, create UML mold ground to lead to go into an Accounting Information Management System realm, body now UML of new technique characteristic, expand UML of application realm, for UML of further the application study did contribute.This literary grace use to object-oriented methodology create Accounting Information Management System, can consumedly shorten an Accounting Information Management System create of time, lowered development cost, biggest of exaltation the credibility of Accounting Information Management System with reuse, so, can satiy accounting system change behind of each business unit need new accountancy’s software of demand, he a very high society value and economy value.This literary grace use to object-oriented methodology create Accounting Information Management System, use UML create system model, simplification mean of system form, thus is every variety the personnel was fast comprehension system dozen bottom solid foundation, as long as he new of need change, ability at original of the foundation of class up, make to inherit enlargement can Implementation new of function, this consumedly exaltation the credibility of the system with reuse, further abundant computer’s application realm.
