The Design And Realization Of Office Automation (OA) System

Office automation system(OA),refers to the use of technical means to improve office efficiency,leading to the office automated processing.OA system to solve their daily management of standardization,and increase the controllability of enterprises, improve the efficiency of enterprises running the basic issues,covering the daily administration,the approval of various matters,office resource management,more than the multi-sectoral coordination office,And a variety of communication and information transfer.In recent years,new technology as the OA system to provide a greater range of applications,office automation system of means from simple client / server form extended to a variety of means of communication support in the form of office,the office system timeliness,effectiveness Be greatly improved.In this paper,JINAN IRON AND STEEL GROUP CORPORATION office automation system for the background,detail the system used by the hierarchical structure based on J2EE architecture and MVC design pattern,Struts framework,Spring framework and Hibernate framework,and discusses the reasons for the choice of technology to enable System has scalability,operability and better performance.Then the three-tier system from the system starting with the structure described in that layer, the business layer,data layer in the layers of durable structure of the system analysis and design and the application of Ajax technology to optimize the pages.This system is based on JAVA + J2EE + SOA system development to ensure that the technical structure of the rational and forward-looking technology.From the lower to a higher level of the system are as follows:database access layer,the permanent storage of data;Java Bean,with the data,control and operation;Web Service to provide external use of Axis WEB service interface,thus realizing SOA;GUI screen,using HTML Ways and means of traditional client.WEB SERVICE full use of open interface and universal international standards.Mainly to empower and certification system and circulation system of official documents as an example,a detailed description of the module management,role management,user administration,Documents module used by the realization of technology.Design of structures based on the J2EE office automation system's overall structure and function modules,and the work flow automation.And completed the coding of these modules to achieve.From the office after the implementation of the system test run results,to achieve the design objectives to meet the day-to-day office needs to address the business office of the inter-departmental processing,to eliminate all types of information within the Group isolated phenomenon,through the implementation of the system,integration The enterprise resources to speed up the flow of information and standardize the office processes and improve the work efficiency to the enterprise has brought certain economic benefits.
