Design And Implementation Of Enterprise Office Automation System Based On Three Layer Architecture

With the rapid development of computer technology and network technology, the amount of information of enterprise of all kinds of important data is also more and more big, to the traditional paper media office mode has far cannot meet the needs of enterprise development, most enterprises urgently need to speed up the application of office automation in enterprise management.Office automation(Office Automation, referred to as OA) is a new way to work, its main task is to use the advanced science and technology, improve the enterprise office efficiency and quality, the competitiveness of enterprises, so the design of an efficient office automation system has been known as the inevitable demand of the enterprise.Based on the analysis of functional requirements of office automation system Beijing Rong Tai Technology Co. Ltd., is designed and implemented for office automation system of the company. Firstly, the paper introduces the project research background and meaning; then, discusses the key technology of system development, mainly introduces the.NET Framework and ASP.NET and C# development language, the three layer architecture and language integrated query LINQ technology is introduced; then, the system function demand and performance analysis, on this basis overall function module diagram drawing system and based on the system structure of three layers architecture, and gives the data access layer, business logic layer and presentation layer design page. Next, describes the system database design, describes the system function modules with.NET technology. Finally, run and test the system.In this paper, based on the ideology of software engineering, the object oriented method, using SQL Server 2005 as the database, using Visual Studio 2008 as the development tool, taking C# as the programming language, to construct the office automation OA system based on.NET platform, simple, easy-to-use enterprise.
