Design And Implementation Of Material Inquiry System Based On Redis

For the electricity enterprise,the material supply and purchase department is responsible for the purchase of materials in the whole enterprise.In general,a procurement project needs many processes,such as bidding inquiry,supplier quotation,contract trial,contract signing and so on.At present,low efficiency artificial methods are still used.To solve this problem,a set of material inquiry system of enterprise is put forward to achieve business inquiries,quotations,bids,winning bid and review.This paper mainly consists of the following parts:1.On the basis of brief description of the system's business requirements,the main participants and related use cases are listed based on the use case diagram of UML.Secondly,the nonfunctional requirements of the system are described from four aspects of security requirements,performance requirements,usability requirements and compatibility requirements;2.Based on Redis,the strategy of caching specific data in the system is designed and implemented.Through this cache policy,the response speed of the system can be improved and the pressure and overhead of the server can be reduced;3.The development mode based on MVVM and the design of Vue.js have realized the interaction between the system page and the data model.Through the MVVM mode,the structure of the system framework is clearer and the maintainability of the system is improved.At the same time,it solves the problem of manual synchronization of View and Model in traditional MVC and MVP mode,and provides a bidirectional binding mechanism;4.The functional modules of the system are designed and implemented,and five functional modules are divided: supplier information management module,inquiry purchase management module,supplier quotation module,review and contract management module,inquiry statistical module,and the detailed design of the five modules;then based on SQL Server 2008,the database table structure is designed;The functions of each module are coded.The material inquiry system based on Redis in this paper has been used in a certain electricity enterprise for nearly a year,and can better meet the daily enquiry purchase of the material purchasing department.The value of the system is: on the one hand,it has realized the target of information procurement of material purchase of national electricity enterprises,on the other hand,it has improved the modern management level of the material purchasing department.
