The Research And Application Of Component Assembly Technology Based On The Workflows

With the increasing scale and complexity of software, the traditional software development pattern is challenged greatly. A new turn of"the software crisis"appears. Software reuse is an effective way for solving this problem. The component technique is playing an important role in software reusing domain. When the application system is assembled by the component, the life cycle of software development is reduced then the software development process is more effective, and the quality of product is warranted.At present , our country existing software development pattern solidifies the enterprise service flow in the application software system, causes the system development to lack the flexibility, the software system cannot adapt the enterprise reorganization, the flow change, the department responsibility transformation and so on many questions. Using the work flows technology separates service process logic from service process realization,this method need not revise the concrete function component realization way, through redefining the process model to complete the system function change or the system performance improvement,It is possible that construction enterprise information system dynamic according to the enterprise service flow, Changed this situation that enterprise's service and flow must adapt the raditional software devolopment pattern.In this thesis, proposing component assembly technology base on the work flows to devlope the purchase_sale_stock management system of the Biology Medicine Garden to meet the current application need.It is studied that the theory of the software reuse technology,the component technology and the method of using the component and the component storehouse carrying on the component assembly. Through researching to the principle of the work flows technology and the component assembly technology, proposed the architecture of component assembled technology based on the work flows. Discussed the application background and the overall goal of purchase-sale- stock management system of Biology Medicine Garden, analyzed the essential factor of the component, the design method to the component, proposed software project development flow by the method of component assembled based on the work flows , the system structure and the solution in the thsis. The purchase-sale-stock management system of Biology Medicine Garden includes 5 sub-systems mainly, which are sub-systems of the foundation data management, the purchase management, the stock management, the sale management and the report form management. The work flow component construction method is used to construct new application system based on the existing components and the new devolepment components. The need of enterprise can be met, and core competitive ability is improved. The software can be upgraded more easily. The validity and effectiveness of this method are illustrated by factual applications.
