The Design And Implementation Of Enterprise’s Express Letter System

Computer network has undergone a great change.The internet has also developed intoa business and information center from the earliest.The company meeting,airlinereservation,hotel reservation, release the order of goods between the companies and so on,these all can becompleted through the network quikly.Internet has penetrated into everyaspect of people’s life, even extending to the basic necessities of life in all areas ofpeople’s daily life, The enterprise’s express letter system is designed in this context.The system development uses SQL Server2005database, uses Java Swing, GSMModem, Java mail API and other Technology. Before the detailed design of the structureof the overall design to determine the solution of some of the features, and complete thefeasibility analysis and prototype implementation of the related technologies. In thissystem, data server and client combine to form the C/S structure, performed by thefinancial staff or system managers, such as system backup, restore, and modify the amountof important operating to improve the security of the system, reduce hacker by WebIntrusion to access and change the possibility of important information. The same time, theuse of the Web client organizations into the B/S three-tier Web client can be connectedthrough the Internet or green application server, send commands, and thus access toservices. The advantage is you can operate from a browser, easy to use, fast and efficient,convenient to the customer with the greatest convenience. For records management,system maintenance functions, record information that the database information to add,query, import and export operations, some of the features involved in technology tothrough VC6connect the SQL Server2005database, and Java code to query and addoperations on the information in the table.In this paper, we research the development of enterprise’s express letter system at first,and then introduce the principles of sending SMS and mails, After that, we made aelaboration of the summary of the system design, function modules, database design,business card folder management capabilities, as well as of the e-mail function’s concreterealization.Finally, we show the system’s effect.The enterprise’s express letter system is a mobile business of application system which sets SMS and E-mail as a whole.The system software is specificallycustom-developed for internal and external needs and applications. It is fully integratedenterprise business promotion, customer intelligence, communication, internalmanagement applications. The enterprise’s express letter system of the role is to helpbusinesses solve internal, corporate and external communication difficult, not timelydissemination of information and other issues. To this end, the system provides functionsas java mail, BSwing, personnel files, information management and so on. The system is atypical example of the GSM Modem and e-mail in the enterprise business applications, soit will be subject to the favor of many enterprises, the best choice for businesscommunications.
