Research And Implementation Of Commodity Traceability Platform Based On SaaS

Commodity quality problem is the great event of national economy, it is closely related to everyone's daily life. Currently in the process of trading commodities, there are a lot of fake and shoddy commodities, the result is that the most consumers and the national economic experience the huge damage. In order to avoid such event occurrence, it's necessary to strengthen the commodity supply chain security risk control and ensure commodity quality and safety of circulation process, so it's very necessary to establishment and development the safety commodity traceability system, which is the development trend of global merchandise trade management. There are some problems about less traceability objects and incomplete traceability information exist in most of today's traceability systems, it brings great difficult to the regulatory authorities. In order to solve these problems, we need to build a traceability platform that can accommodate more and more enterprises and varied type of merchandise. Combined with these actual demand, a commodity traceability platform based on SaaS is designed and implemented. The main research works are as follows:(1) The thesis analyzes the theory of SaaS which includes the advantages and basic concept of SaaS, the maturity model and data model of SaaS. Based on the detailed analysis about the concrete demand of the commodities traceability platform, construction the overall framework of commodities traceability platform based on SaaS.(2) The configurable method of application service based on SaaS are researched. Firstly, according to the multi-tenancy data storage characteristics of application service, a kind of data configurability method of application service oriented multi-tenancy are proposed. Secondly, analyzed the access control method of SaaS application based on RBAC. Finally, basis the theory of workflow, the thesis puts forward an implementation method for operation flow configuration by business process analysis and modeling to solve the application service flow configuration problem.(3) According to the data exchange problem of the commodity traceability platform overall framework, this thesis combined with middleware and web service technologies to designed the model of commodity traceability platform for data exchange base on web service data access middleware to solve the problem of heterogeneous traceability information stored in different databases which is difficult to integrate.(4) Based on the research results above, the thesis design the function modules of commodity traceability management platform and each application services subsystem; then carry on the modeling to management platform and application services subsystem by using UML modeling; finally under the framework of.NET Framework 3.5,using ASP.NET development technology integrated development environment and SQL Server database to achieve the commodity traceability platform based SaaS, and test the operation performance, meet the needs of user experience.
