Design And Implementation Of ERP Sales Management System Based On Opentaps Framework

With the continuous development of modern enterprise changes,the traditional way of sales management can't work well,ERP system absorb the modern scientific information technology and advanced management ideas together,sales management system is an important part of ERP system,It can conduct a full range of management of the company's sales activities scientifictly and efficiently,also can make rapid response to customer needs,coordinate the enterprise procurement,production planning,manufacturing,inventory and other departments to complete the order contract,thereby enhancing the operational efficiency of enterprises to improve the business situation,so enterprises can develop quickly and steadily.The researh is based on the core business of sales management department of HY company.Due to the lack of the original system in the design and development of the original system,the late maintenance and development difficulties,based on the needs of the relevant departments and the original system functions based on the summary of the use of Opentaps framework,combined with domain knowledge,sales management system to achieve design.This paper begins with the introduction of the research background and significance of the sales management system,analyzes the problems why original framework can not meet the needs of modern sales management,and analyzes the status quo and direction of ERP,system sales management system and domain model at home and abroad.Then it introduces the theory and technology used in the sales management system,analyzes its characteristics and advantages,and explains its successful implementation of the system.On the basis of these,through the analysis of sales management needs and related business processes,the sales management system is divided into six modules The function of the module to design instructions,the use of domain modeling knowledge of its domain division,abstract the entity,the aggregation of the root,to build the system domain model.Finally,the system implementation is based on the Opentaps framework,and the business logic layer is constructed by the entity engine,the service engine and the event engine.The presentation layer is constructed by ExtJS and the scientific sales forecast is realized by BP neural network algorithm to ubstitute for human subjective predictions.The ERP sales management system that successfully achieved meet the initial business needs.It is based on the application of the framework of the Opentaps that absorbs the DDD technology and B/S architecture,which makes the system intuitive,user-friendly,easy to maintain and expand,help the development of personnel to facilitate the expansion,to adapt to the HY company's frequent business changes and increased functionality.
