Development And Application Of Instant Messaging Software For Enterprise

The main function of instant communication tool is a real-time information exchange, it appears to promote the rapid development of communication means between people, makes people’s communication to achieve real-time, instant communication, exchange information with others. But the instant communication tool on the market size, and did not get the better popularization in the enterprise. For many small and medium enterprises, a feasible, convenient, secure enterprise instant messaging system, is very necessary.Development of instant communication system of the design is to the enterprise needs, the main objective of the research is to solve the practical application of small and medium enterprises. The system design in independent LAN, simplify the server distribution problems, to strengthen the enterprise internal information confidential. The overall use of the JAVA platform, and uses SQL Server2000database management system. Through the use of the instant messaging system, can promote a good communication environment in the enterprise, you can speak one’s mind freely, no matter what level of staff, can timely communication, also can promote a text conference, many people, many departments can through the timely communication tools, network meeting held the text, which can improve enterprise work efficiency.Real-time communication software is high, especially in low layer communication software, real-time, concurrency is higher. Therefore, you must select suitable for the software development method for real-time transaction processing. This paper uses software modeling method, the specification case, make the system definition, and identify the relationship between the actors and use cases, to define the use cases.The system design includes two parts of the server program and client program, in which the client program includes communication module and personal information maintenance module, server side includes message forwarding module and the backstage database maintenance module. The client layer is the interface part of the application, the service layer includes business process logic specific. Customer service is the bridge between layer and data layer, it can accept client requests, and then according to various request corresponding treatment. The data layer is mainly used SQL Server2000as the database management tool. The main form of which server contains the core function service terminal program. The server administrator can through the form to perform a series of operations such as:start the server, check the server configuration information, display the online user, server and other functions. Update the user basic information maintenance, user interface used to complete the user information to add, delete users, the basic operation of the user.The safety aspect, the system is applied to the enterprise, using encryption in message passing, data encryption. Socket network programming is the basis of the system development, the server has a process or multiple processes in port waiting, request connection, if the connection, then according to the design of the data exchange mode for data transmission. The client requests a connection server, connection after successful communication.This system integrates advanced information communication mode, with a fast, affinity interaction communication, and can be used in combination with e-mail, mobile phone and other enterprise application office procedures, successfully created a new platform of modern office. With the different needs of enterprise internal work, will continue to carry out and perfect the enhancement of the function of each module, which makes the system more efficient, fast, the service for enterprises.
