Research And Implementation On Method For Merging Multi-MapReduce To Optimize Global Makespan

With the rapid development of enterprise information management,the business amount and its complexity of the application system of the enterprise such as ERP?OA?MES?PDM are increased.In order to integrate the information resource contained in an enterprise to solve the problem of information island,insure the consistency of the data in each system,make the users from different depart to work coordinately,and support the innovation and the high level decision,it needs to develop a collaboration platform for enterprise integrated business to coordinate the resource from different systems and satisfy the long term development.The dissertation analyzes the current status of the enterprise information management,investigates and analyzes the requirement of the users,based on VMware environment,develops a collaboration platform for enterprise integrated business by IBM WebSphere Portal of IBM company.The platform is mainly based on the requirement of integrated enterprise daily work.In order to meet the needs of the employees,the design of the platform system architecture is used of the technology and methods about the software engineering.This dissertation mainly researches the design and implementation of the integrated enterprise collaborative platform,analyses the overall functional requirements of this platform,expounds the entire process which is beginning with the analysis of the system requirement and ending on the design and implementation of the system in detail.The system achieves the function modules of the document management,unified user management,business information management,overall query management,mail management and so on in the same way it tests the function and performance of the key modules so that it could finish the target of the enterprise cooperative office.The platform has some typical industry characteristics.The platform requirement analysis is based on the operational characteristic of the enterprise and in the same time the design idea conforms to the modern enterprise management concepts,and can meet the requirements of the integrated information during an enterprise's comprehensive work.The platform can adapt to the requirements of the grass-roots business,and the system maintenance is not very difficult.Through the platform,the employees can get the information exchange and sharing more conveniently,the system administrator can improve the efficiency and convenience of the information maintenance,and can achieve information integration.The success of this platform can provide a useful experience for the enterprise information-based construction,and has a certain guiding significance to the development of enterprise office automation system.
