The Design & Study About Network's Teaching Resources System Based On Distributed Database System

Database, is the progress of the relation database system particularly, make the computer realm take place the variety of the nasty play. In now society, any information handles can not get away from it.At the same time, another realm - network with its technical application and expand, created terms for orientation more applications continuously. Especially Network combined with the database technical have becoming a new research realm - Distributed Database System (DDBS). Realizes and establish of Distributed Database system absoluteness are not simple combination of networks with the distributed database, but two kinds of technical blend with permeate mutually. What it wants to manage is a not single a database system but several databases which distribute in many different geographies position system.Although DBS is based on the concentration type database system, but it have its oneself characters and theories foundation. Under the push of the other realm computer technical, particularly is that the information superhighway development quickly, makes the DBS more active, thesome techniques is also the foundation that study the new development of DBS from now on.The construtism is booming rise and network teaching system is developing fastly at present, If say that construtism indicate the direction, then network technique and latest development in databases provid the powerful impetus for the network teaching.This thesis begins from the construtism, look back synopsisly the development of the network Teaching & Resource system and the present condition, we discuss around the application of DBS in the network Teaching & Resource system. The main contents includes: Review briefly network Teaching & Resource system present condition and theories background; Describe the latest development trend of the network teaching system, such as Agent, the WEB Usage Mining application, intelligence etc; According to DBS principle, adoption B/S and C/S, application ASP or . NET technique to design a network Teaching & Resource system based on DBS, including primarily examination system, student status management system etc.;...
