The Systems Analysis And Design For Office Automation

Today,the whole world is full of increasing business competitions. Innovation as well as effectiveness have been the new symbols of competition, whose essence being technological persons, information and administration, as a result, the methods to rise the levels of administration, effectiveness as well as the veracities and swiftness of messages have accompanied the utilization of persons with abilities, playing a very important role in the modern business world. This is the issue we are never going to neglect. Information, which has been the master of this time, is the bond as well as the activator. With the fast development of information technologies and network, computer has been a exactly indispensable tool in our daily lives when China's information industry is rapidly advancing. The application of electronic technologies in the affairs of government, have made a tide of computer administration construction and the office automation system(OA) emerged, all these have rose the effectiveness of people's jobs. The popularity of the OA not also dues to its embodiment of administrative effectiveness and methods, but depends on the coverage of the links between layers of administration. So, we users are looking forward to a better office software with more completeness. The OA, with an ability that enables us fuel the measurement processes of non-measurement and measure the messages that are unable to be displayed in figures in the largest possible scale. All these, however, base on the realization of office software, which serves as a channel or a storehouse holds information as well as the activator. In these days of rapidly developing information, the OA technology has fundamentally changed in both its meaning and extension. Thanks to the introduce of all sorts of technologies, people are enabled to deal with more information and businesses such as daily arrangement, documents transfer, schedules of meetings and the publication of messages. With the development of network communication, scattered transaction as well as data-base technology, paperless operation in the enterprises will be seen by means of the sharing of network resources and the work-in-tandem. OA that bases on computer network adopts software technology that comprised by groupware, with a combination of flowing-work management technology, founds an easily-extended-and-transplanted information management system whose base being groupware, which is able to be rapidly reconstructed so as to fits the brand-new demands of enterprises for the OA system. The key technologies of the system being the groupware-software and the flowing-work management technology. It solves the problems emerge in the traditional flowing-work and makes sense in the flowing issues: The lagging in operating process The inefficient operation. How to chase the process of the documents transfer. How to supervise the job effectiveness The consuming of paper. The object-oriented technology is one of the key technologies to The Systems Analysis and Design for software. This technology is unnecessarily makes the analysis and design easier, however, it brings system to the formally complexities and consequently brings better software produced by a group. Software with great complexity will ask for a explicit mapping of the code as well as the gradual evolvement, which will have influence on the maintenance of software, especially important to the key business application software. It is a comprehensive issue that how to utilize the OO technology. The utilization demands not only analysis, design and programming of this technology, but the modeling and exploring tools. Furthermore, experience and sound exploring process are also necessary. The OO technology are still developing and gradually perfecting itself. As a practice, this composition cuts in the network OA system go deeper into the flowing-work technology of the OA system. With some instances, it analyzes the characters of the flowing-work, it makes models for every element in the technology in the modeling language. The composition embodies the opinion that model serves as the pre-digestion of the reality to problems; and in the other hand, model serves as the pre-digested reality. As a result, modeling is a process in which people catch the essence of things. Throughout the composition, the author rises demands on the software side bases on the OA system and, by analyzing the field of the issues, get a simple and visible descript model that depends nothing of concrete application technology environment. The author finds out "what is the target", and explains the functional demands into the software concepts so as to catch the conduct of issues, and finally get a rough model of the objects that composed in the whole plain which depends on the screened details. Plains are pre-digested when designed. The User Case modeling technology is used to catch and descript software demands, and the UML is used to the designs...
