Functional Design And Implementation Of JG Trading's Contract Management Systemtable Of Contents

With the rapid changes in the trading system and the increasingly information-based construction of enterprises,JG Trading Company,as a large-scale trading listed company,is urgently building its information technology.Under the circumstance that JG Trading Company is highly regarded by the industry,in order to become the first-class trading company in the industry and enhance the core competitiveness of the company,the company chooses to further improve the management of trade production and management on the basis of the construction of information systems.Make improvements.In each business management,JG Trading has established a corresponding information system and has played a significant management effect.In spite of this,in the face of the increasingly popular information systems and continuously improving corporate management levels,joint operations also have an increasingly important role for companies.As with other trading systems,there are increasingly serious information silos in numerous information systems..In order to enhance the key competitiveness of enterprises,they usually adopt methods to improve the management of production and management in the trade field.The establishment of an enterprise information system is of great importance to the improvement of management efficiency and collaborative work of enterprises.In combination with the actual production and operation status of JG Trading Co.,Ltd.,the Production Management Information System(PMIS)has been used.In the case of an Enterprise Information Integrated System(EIIS)and a comprehensive service management system,based on the full use of the existing hardware and software resources of the existing system,a set of information sharing systems that can both achieve internal information sharing can be effectively implemented.The contract management system that meets the needs of the market business and JG trading company's future development plan is the core content of this article.The computing system model designed in this paper adopts the JAVA 2 Enterprise Edition(hereafter J2EE)three-tier structure system.Its purpose is to allow the system to complete the scalability,identity,and cross-platform issues of the business,and to increase and use the server between the client and the server to change the consistent two-tier structure into a three-tier structure.After the success,it will solve the problems that the company's business is actually facing,such as cross-platform and scalability problems.The system structure design also has the characteristics of different application systems of cross-platform compatible enterprises.The design features of this structure will increase the existing information system of the company.Security.The Extensible Markup Language(XML)data exchange technology utilizes three layers that are relatively independent but are interconnected,allowing user display,service encapsulation,and data acquisition in system development to be independent of each other,and using the simplest data abstraction layer technology.Let the data of different structured data sources be exchanged,and the purpose of rapid and convenient system integration is achieved.At the same time,the seemingly infeasible integration between heterogeneous systems becomes feasible.JG Trading Co.,Ltd.uses the J2 EE three-tier architecture,XML and other technologies to create a planned contract management system,so that the production management system(PMIS),enterprise information integration system(EIIS)and other application systems can be integrated into planning contract management.Therefore,the ability to properly apply XML and other technologies in system design is the key to centralized management for successful planning and management.This article does a key research around the following issues:1)Exploring the important influence on information construction brought about by the reform and reform of China's trading enterprises,analyzing the current status of planned contract management in the information systems currently used by JG Trading Company,and establishing the defects resulting from the analysis.The necessity and importance of the company's unified planning of the contract information management system;2)Study system conditions and establish the purpose of establishing a contract information management system;3)Study the integration model of EIIS and PMIS.In the enterprise production and operation management structure,business systems and office automation systems(Office Automation,hereinafter abbreviated as OA system)seek appropriate measures for exchange and preservation of project contract information;4)Research enterprise information integration technology and integration platform architecture;5)Exploring the interface standards in enterprise integration systems and analyzing the skills of XML technical standards in planning contract management systems;6)Exploring the flow of EIIS and PMIS documents to each other,and has completed the integration of database resources for enterprise documents;7)Study the status quo of using the planned contract information management system in the actual production and operation of an enterprise.
