System Analysis And Design Based On OOA Agricultural Product Wholesale Comprehensive Trading Platform

Implement of traceability of all kinds of transaction information,how to let people eat food safely,how to improve the service quality,efficiency and the management level of the agricultural product wholesale market,,reduce the market operating costs,attract more businesses,to increase the profits.This topic introduces the modeling of the system and the design process.It's summarized from the present situation of comprehensive trading platform and design schemes,and comparethe requirements modeling,development mode and other traditional modeling,development mode,and describes the key technology and principle of treatment.development efficiency and quality of system.This paper completed the system analysis and design of integrated trading platform,using the object oriented based model driven development method,design a business model and demand model of integrated trading platform abstraction,use the corresponding UML tool for modeling,showing how the requirements into system design,system design through the development of seamless integration.Combined with the project of demand uncertainty,easy to change characteristics,the use of object oriented MDA combination of ideas,so that the model can improve constantly in communication with users to improve,so as to continuously guide the user review and standardize their business needs,the potential demand change can be found in the earlier period,reduce the risk of and cost in the construction and operation of the system.MDA,and finish the model construction through modeling tools,show the direct conversion process of analysis model and design model,and just make the tiny adjustment of the design model and directly convert into coding framework,only needs t a small amount of code can realize system functions,thus greatly enhance the system's accuracy,completeness and efficiency of development.
