Design And Realization Of Office Automation Management System Of Water Investment Group

The project management of water conservancy projects involves the parties involved in the construction,design,construction,supervision and other parties,and need to deal with and coordinate the project cost,quality,schedule,materials and other aspects.Today’s society is in the information economy as the core of the era of knowledge economy with the continuous development of business,the traditional business model has been constantly challenged,especially the large-scale development,decentralized office management pattern.In which the level of information management directly determines the level of project management.In order to ensure the security of information under the premise of the Group and its subsidiaries to be able to do information,information sharing.Through the document processing,attendance management,assessment management and contract signing sub-system,to optimize the work process and integration of resources and other objectives.Employees in accordance with the provisions and design procedures in the online to complete a large number of cumbersome administrative and daily things.In this way,both can break the constraints of time and space,but also to avoid the division of the division process caused by the smooth flow of the problem.Through the comprehensive analysis of similar applications at home and abroad,it is determined that the development platform of this system is based on J2 EE and the sub-EJB simulation function is added to the system.It can support a variety of middleware in a variety of middleware support SERVLET2.1,to achieve office automation.System support in the windows,Linux,Unix operating system to run.This paper introduces the structure of J2 EE and the composition of EJB.In addition,the advantages and disadvantages of J2 EE and EJB were systematically analyzed.Follow the principles of software engineering design ideas,From the economic and technical aspects of the system needs and application of the feasibility analysis,from the daily work of the actual situation,analysis of the attendance management,assessment management and contract management functional requirements.The system uses modular design ideas,detailed division of the system’s role and function.And then from the system function,the attendance management,assessment management and contract management module for functional analysis,and a summary of the design and detailed design,the system also uses Web Services to achieve data exchange,to solve the relevant needs of the assessment system.The system implements the functions of attendance management,evaluation subsystem and contract management subsystem.The paper focuses on the analysis of the system security problem,and completes the safety mechanism design and related technical means.After the system design is finished,the functional aspects of the system are tested,and the system is analyzed according to the test results.The system to achieve a full range of standardized unity,high quality and efficiency,transparent management and collaborative office objectives.
