Three-tier Structure Based On B / S Mode Network Office Systems

Along with the technological development, the social rhythm speeds up quickly and continuously.The high-tech application is exactly this social development's accelerator.While the information of each profession quickly developing, the information of the government agency also has started early.The country has spend a lot of money on hardware equipment, and a great part of the organizations and units all have provided with the computer equipments. The current key is how to use these computers. Therefore, to find out an information system that suit the government agency seems to be particularly for importance.At present software industry is being placed in a process of which from the traditional mode of C/S( client/ server mode ) converts to the the mode of B/S( browser/ server mode). B/S mode software( browser/ server mode) is a kind of improvement to the mode of C/S along with technical rise in Internet. Under this kind of construction, the applied business in software logic is complete to carry to realize in the applied server, the customer performance is complete to carry to realize in the server of Web. The customer carries a demand and then the browser can immediately proceed the business handles. This is a kind of completely new software system structure technique.This kind of mode even becomes the head that now apply software chooses the system mode.Three layer construction CLIENT/ APPLICATION SERVER/ DATABASE SERVER), turns up with the foundation of the summary to the C/S mode construction. It is seperated to three parts: Customer interface layer, business logic layer, database layer. And three structural concepts in layers has seeped through the B/ S application development realm. B/S system construction has got the incomparable advantage at data safety, data consistency, data solid hour sex, and serve to respond to on time sex and network application. This catered to the government agency unit work of on time sex, the characteristics between same and data safety.The system of networks transact, which is based on the mode of B/S of three structure in layers, is a networks transact interface.The main aims are that around the government's daily work pursuit primarily, simplify job step, increase the work efficiency.Its contents includes the information sharing, the business handling, the data collecting to process, the data saving, information exchanging, on-line study.The system this text discusses is Jinan City personnel bureau that manage the welfare transact system designed and developed by myself. This system is constituted by three contentses which closely connect to each other: grass-roots version, handle center version, control centre version three Classes edition.Three legal power of editions goes up one by one in order. The thesis is totally divided into five parts. The first chapter is to whole item engineering generally introducing, the second, threeth and fourth chapterses detailedly introducing author design combining developments south City personnel bureau network welfare transacts the system.Among them, a need for detailedly describing network welfare transacting system analysis;A design for is network welfare transacting system project;A problem for introducing this system development in the process resolving with adopt the related and technical research.Finally, pass the movement result to transact the system to JiNan City personnel bureau network welfare to transact to the government agency network applied foreground and development directions of the system do to analyze.
