Design And Realization Of Instant Messaging Software For Enterprise

With the development of computer network technology and the ripeness ofnetwork communication, instant messenger software provides better service, instantmessaging has become a comprehensive network communication tool. large andmedium enterprises have special requirements and security requirements, which isdifferent from public instant messaging software can meet.Starting from the actual business requirements and conditions, combined with theenterprise personnel structure, characteristics, working methods and basic requirements,this paper analyzed the basic functional and performance requirements of the enterpriseinstant messaging software system. Combined with the successful experience of instantmessaging software system that was applied successfully, a instant messaging softwaremeeting demands of large and medium enterprises has been development. Because theenterprise client is relatively limited, in order to ease the security management, thedesign uses a client/server (C/S) model. In the instant messaging system with C/Sstructure, logic architecture consists of interface layer, business logic layer and servicelayer. This design has a loose layered structure, a higher layer can call any lower layerservices. By this way, program can been separate, and was easy control, easy extension,easy to allocate resources. On the protocol between client and server, the design willestablished a Common packet in client server, and design the contents of the packet forstoring message exchange agreement. This design adopts JAVA language, using JavaSocket technology, using Eclipse as the integrated development environment, usingMySQL6as the database platform. This article has made the detailed elaboration on thedesign and implementation of business function modules，he corresponding databaseand the network function module.Finally, in order to verify the operation of the software, the functions andperformance of the instant messaging software has been tested, the basic functions testof the samples show that the software can successfully complete the basic function ofdesign. Through the test the integrity of the instant messaging software system waseffectively guaranteed.In general, this paper introduces the demand analysis and designtechnology selection, system structure, as well as the final realization of a instant messagingsoftware system. There are some exact value to guiding the implementation of instantmessaging software system.
