Design And Implementation Of Engineering Contract Management System

With the development of national infrastructure,the management of engineering contracts is more and more important,it is very important to strengthen the management of enterprise projects and manage the project contracts.Strengthen the management of the project contract,to a certain extent,reduce the enterprise project budget,improve the level of enterprise management,to a certain extent,can reduce business costs,but also for enterprise decisionmaking to provide some support for the good development of enterprises to provide protection,At present,the contract management business inside the enterprise is more complicated.There are so many types of contracts and management contract departments,this has caused chaos in enterprises' contract management.Contract management's paper management is very serious,the contract change cannot take effect in time.It is unable to timely control the progress of the contract and obtain early warning,there is no way to carry out the risk control,the responsibility cannot be carried out,and the specific work cannot be pushed forward,resulting in the delay of the project and so on.So the development of a project contract management system is necessary.In the process of project contract management system development,in strict accordance with the general process of software development software development,the use of advanced and technologically mature Java language for development,due to the more data involved,so the development process used in the database management system For Oracle,to ensure that the system data security and operability.Using the Spring MVC architecture,and finally it designed and implemented a set of engineering contract management system based on B/S mode,during the demand analysis,we completed the business requirement analysis and data flow analysis of the system,it completed the basic information management,supplier management,customer management,contract management,contract,contract performance,contract end,monitoring early warning and specific functional requirements analysis,statistical analysis,etc.,through the system use case diagram and use case description.After that it finished the non-functional requirements of the system.On the basis of demand analysis,it completed the outline design and detailed design of the system,it mainly completed the overall architecture of the system design,network deployment situation general design,system function structure,database design of the system,and designed the relationship between data entities and data table structure.Then through the sequence diagram,activity diagram and class diagram,it completed the main functions of the system design process.In the process of implementation,on the basis of design and demand work,it mainly completed the implementation of the environment,the main functions and the main process of the functions.After the development of the system,It was necessary to test the system for functionality and performance,we performed functional structural tests through test environments and test cases,After that,we performed system integration,system security reliability,network and database testing,and stress tests.After the system has been tested and passed,it can be put online.After the design,the project contract management system is systematically tested.The test shows that the contract management system can be designed and implemented according to the demand analysis in the development process,and the various functions of the contract management are realized,and the service management system has achieved good availability.Contract management system design requirements.The implementation of the system changed the traditional paper management status quo,realized the whole life cycle management of the contract,standardized the contract management process,improved the overall contract management efficiency,reduced the contract management cost.With contract management system it can monitor each contract,by setting time limit,it can implement system automatic warning,realize the contract performance monitoring,the comprehensive analysis of contract data,and provide support for management decision.
