Research On Technology Of Reconfigurable Software Development Platform Based On Component For Agricultural Products

Referring to E-commerce Trading System for China's Agricultural Products , this paper studies the component-based reconfigurable, extensible software development platform technologies . Following are the main aspects of the research.The components and component library modeling technique in industrializing software production are explored. The main component model in software development process is analysed and built, which is based on the software life cycle and development phases. The paper also discusses the software component library system and referential model and furthermore proposes such 3-dimension data space model about component library as lifecycle dimension, hierarchical dimension and version dimension.The organization and management of the components in industrializing software production are analysed. The supple segments coding method based on the phrase demarcation in software life cycle is proposed. The basic concepts about virtual Item and virtual BOA are defined. The paper also puts forward the component arrangement method based on reconfigurable relation and builds the distributed organization model of product data on the basic of virtual Item andvirtual VOA after the reasonable division of the software component granularity. The basic concepts of the BOM list of software components are proposed and the main types and view space of BOA are defined and so are the key characteristics of the main sub-views .Furthermore, we explore distributed database model of of software components, analyze business demands in multi-allied development circumstances of complicated software system, and establish software information-associated relational model in distributed circumstances.The reconfigurable software development platform technique is researched. The theory of single modeling data source technique and dual engine software platform is proposed, and the reconfigurable software development platform with C/S and B/S configuration, as well as its key components are designed. The development process of application system based on reconfigurable software development platform is also analysed.The main business process and mode of e-commerce are studied. We build the key business model, propose the basic e-commerce theory of supple deal mode and the dynamically configurable deal platform.and analyse the dynamic parameters and the essentials mutex relational model.The e-commerce system about agricultrual products flow is developed. The main framework and business rules of e-commerce are proposed. Based on the reconfigurable software development platform,we design and develop the E-commerce Trading System of Agricultural Products in Circulation Field.
