Research And Implementation Of Self Service Print System Based On Componets Technology In Three-Layer Framwork

The theory and technology of component is deemed as research hotpots in computer software area.How to fast and well build a robust and high-quality component sets is a persistent target for system developers.The system consisted of components have a lot of virtues such as upgrading simple,convenient maintenance and development period shorted and so on.In the context,to solve some technology problem which abstract components from system design documents rapidly and accurately,we launched a research which aim to recognize and pick up concept components,match logic components and entity components,rapidly build up self-service printing system.The research findings maybe guide researchers to how to rapidly gain system components from development documents.Main items including intelligent recognized components,match logic components and entity components from development documents,new technology application and so on were researched in this project.The achievements are as follows:1.The design documents were translated into JSON documents by automatic tool.Aiming at these keywords and semantics,we were able to get concept components,further logic components from JSON documents by virtue of Agent.2.On the basis of login components gained above step one,target system architecture was constructed by a method based on context constraint analysis.Furthermore,its integration and accuracy was effective tested.Mapped design documents into JSON documents,whose accuracy was tested by OWL semantics logic.3.Semantics on syntax level and knowledge between logic components and entity components were contrasted and matched by means of body technology based on profile description.Meanwhile,the congruity between logic components and entity components was studied by MAS.4.With the technologies and methods proposed in this dissertation,campus self-service printing system was accomplished by object-oriented thinking.It includes many functional modules such user login module,uploading files module from remote location,E-wallet,self-service printing files,print fee and automatically cut payment etc.Finally,we used proven JADE platform and its multi-agent technology to further test the validity of methods which intelligently recognized and abstract components,get many logic components from self-service printing system development documents and accomplished matching between components logic and entity.Overall,the target was achieved.The achievements can provide developers references for rapidly recognizing and abstracting components during software development.
