The Design And Implementation Of Intranet Office System Based On J2EE Technology

With the high development of the information construction of china and the rapid economic growth, the gap such as Logistics, information ,technology funds lobetween enterprises and public institutions has already been reduced. Constantlyssing competitive advantage , whether or not there is a new competitive forces emerged, it became a major topic of domestic enterprises. However , enhancing the management level in the company, improving the flow of office administration and business processes, strengthening the efficiency of internal communication coordination, implementing the maximization of sharing of the internal resources, reducing resource consumption, enhancing service standards bodies have become important new means and methods to enhance the new competitive strength .Yet , the office automation system in numerous ways and means play a most important role . Using advanced computer and communication technology as primary means to achieve business-critical and applicationoriented office, and set up a unit that covers the entire information platform for office automation. The adoption of network technology, mobile office units implementation, resource sharing, coordination and efficient transaction processing mechanism set up a unitbased real-time exchange of information and effective channels . They also set up high-quality, highly efficient information network to provide a convenient and effective leadership of the Event tracking and monitoring tools, in order to achieve modernization office, information resources, transmission networks and user-friendly management. Office automation refers to the true meaning of not using the computer easy to send and receive e-mails or deal with day-to-day office, but through a wide range of applications of computer system so that independent workers can share information , cooperate with each other , telecommute , and regulate and control job flow, such as transfering documents, the approval process, planning and supervision .It can help to improve the efficiency of business office, information sharing and achieve efficient coordination. Applications based on the office computer system can be referred to as office automation. Firstly, set up a network ,automatic ,efficient and cooperative platform ; Secondly , make business process management normalized, rational, efficient, through the advanced management idea ; Thirdly precipitate culture and information resources by the information collected; Fourthly , provide effective supervision for the leadership means and try to avoid out-of-control case ; Fifthly ,achieve centralize management.With the constant development of enterprises, company issue files, the collaborative between the department, or between staff, information transfer, approval instructions, plans, case tracking, time management, meeting notices, etc., are in the state of manual management ,make poll information much more difficultly. Existing information management system for the supervision and control of the job has become backward, more branches , and not very timely messaged. At the same time , the use of various software applications are in an independent status . There exists a general "information island" phenomenon.As the rapid development the economy and science,technology,information management platform for modern enterprise management are inevitable. The urgent need for construction companies with the group of characteristics of information management systems is to meet corporate governance requirements and development needs and to set up a advanced and sophisticated technology platform in one of the applications, high-performance, high reliability, user-friendly appearance, convenient operation, easy-to-use efficient management information system . As a scientific, accurate, real-time and visual system it can reflect the company as a whole. It also can Provide the basis for decision-making and build a centralized management platform for information exchange when enhance the level of modern management and increase cost effectiveness.Online office system for the enterprise is set up to disseminate the message of the internal contact for the company to work together and achieve information management and implementation of distributed applications . The network flow information system is constrainted and management process is specialized so in the pursuit of their ideals such as management standardization and institutionalization of flow. System privileges, application process can be determined by the system administrator in accordance with different user rights, the role of different settings excluding the computer system administrator unauthorized access to information and lead to the consequences. Combination the security technology encryption such as encryption,decryption and authentication technologies, allowing the system to be reliable security protection. At the procession of Internet transmission, data security can be guaranteed.In the architecture, the system use B / S structure, three-tier architecture of J2EE and the design pattern of MVC (Model, View, Control) .The structure maintains the stability of system. At the same time, the system uses the combination of Hibernate and Struts, so the operational control and data access for system more convenient and safer.In the design, the system uses the idea of object-oriented software engineer, in accordance with the needs analysis, summary of design ,detailed design, coding and implementation, running, testing, achieve a systematic analysis and design work.
