Design And Implementation Of The Small And Medium-sized Enterprise Lan Instant Communication

With the increasing popularity of computer networks, the network has become an important tool for people to information and access to information, the exchange of management information essential. LAN instant messaging appear to bring a great convenience, but also brought time and save the economy. Today, instant communication of information exchange tools used in various industries.

This communication system is widely used in internal communications for small businesses, can greatly improve the efficiency of workers, in-house staff to facilitate communication, but also to create a quiet working environment, is a modern enterprise indispensable auxiliary tool.Combined with the corresponding research topics into law a broad and in-depth research, mainly in literature research, empirical research methods such as in-depth research and analysis of issues in this process, mainly in the literature study conducted targeted research, combined with previous research scholars instant communication technologies extensive research and analysis, which will be the future development of SMEs instant communication will exist to promote the role can not be ignored, especially in the current society and economy is undergoing profound changes how to make the advantages of instant communication function and the release of huge advantage in SMEs will be a very significant research topic.This study makes full use of database technology and the use of object-oriented programming language--Java language, with the enterprise LAN, opened up a business management propagation channels, achieve a convenient link corporate internal communications, messaging and corporate announcements. Internal communication systems development and design process, using a combination of top-down and bottom-up system design approach combines. Can be used in the development of Java Swing technology and Java6.0 new Java DB database cross-platform application development. System is based on UDP/IP protocol, information communication, system settings, file transfer, access to public resources, visits five other host security functions carried out by the deep and shallow exposition and analysis.The main objective of this project is to combine the practical needs of SMEs managed to establish a instant communication system, easy to maintain, easy to expand, according to the modern enterprise management model for structural design. To achieve internal software set of information management to establish their own characteristics in the enterprise and instant communication as a whole. To reach the information communication, system settings, file transfer, access to public resources, visits the other host function.
