Design And Realization Of Network OA System Based On Workflow Technique

The Office Automation, abbreviated as OA, it is a research focus of the computer application at present, It means the automation of official information processing mainly. It uses various kinds of advanced information technologies and integrated technology. It makes to be originally people come engaged in handle official business progressively at many equipments and various kinds of man-machine information systems help to finish, Thus reduce labour intensity, avoid working repeatedly, improve the working efficiency, and the main purpose just to make better economic benefits.In recent years, the popularizing and develop at full speed of computer network, has offered the strong information processing platform of the function, Have brought deep influence for work and all respects, such as daily life,etc.. The popularizations of network offer the convenience to office automation terms too, create a integrated environment of handling official business, Meanwhile with the quickly social rhythm, the social information expands rapidly, Each enterprise needs a whole set of automated office system to help information processing, to gather information urgently too, and to get information pass on and share.The main characteristics of Office Automation is becoming on technology in coordination and at network technology now . Because the user uses the random diversification with the demand in the way under Web environment, Require systematic global design, function divide,, user interface design and pay attention to systematic common ability and easy to spend quality further structure data base, Should also enable having relatively strong dependability and maintainability systematically at the same time. Because of the restriction of the function of the browser in addition, use static HTML simply; Can't already have been satisfied and realized the complicated need, the change of these systematic structure must require adopting brand-new network analysis, design method and technology in the course of developping . As a result, we propose workflow and Web technology combine together to design and develop the system. To handle official business the development of automated system there are their special principle and method to other the developments of software, Especially under the envirment of Web, this kind of distribution type, the commonability and easy to expect very much with the quality to the system, This analyse through demand and network analysis, collect and publish in common use functions among them make up , Its element task to collect the basic work flow. A" workflow" is a consistent job course or execution of several pieces of close and relevant consistent job course . In the course of carrying out in this, The file, information or task are transmitted between participants according to certain course rule. Work flow have level quality, namely relatively complicated work flow and divide into comparatively simple work flow a series of further, The jobs of lower circulate certain course rule form a series of on the senior level works as much as all kinds of flow.Workflow meta it flows to be relatively the works of the lower flow this kind, It to have nothing to do with concrete organization of user's unit and suitable for organizations work the works of the course flow according to certain course rule. Through drawing workflow meta and make systematically function have most heavy commonability and easy to spend quality.This text turns systematic design and development into the example with the handling official business of the ChangChun movie century city, It analyses the demand of the whole system at first andintruduce some important functions, and analyses several concrete parts included of the modules, therefore give the overall design idea of the system.Second, explain how to use the method of workflow technique at the OA system realization, and how let a work flow manager with certain authority realize to define a concrete workflow in the system by oneself, Establish the file layout template worth pu...
