Based On Hierarchical Agent Structure Of The Modern Distance Education Resource Organization Management Methods And Technologies Of Research And Design

The modem long-distance education is a new education mode that appears with the development of the modem information technology and it is the principle means of everlasting studying system for the persons who deve]~op the era of knowledge economy. The modern long-distance education system consists of teaching system, teaching administrative system, teaching resources system and network communication. At present, our country is short of long-distance education resources, so how to enrich and share the education resources in Internet is the biggest problem our long-distance education faces. When we enrich the education resources, the more important thing is to share it. And in order to realize the share of the resources in Internet, we must set up a managing platform for the education resources in Internet. It can be said that the day when the sharing platform for the education resources in Internet is founded, the day of sharing the education resources in Internet comes. But the foundation of the managing platform for the education resources in Internet is very hard. For this, we are undergoing the research and design of the administrative and managing teaching resources on the basis of layer agent. The article firstly introduces the modem long-distance education system, and then puts focus on researching and analyzing the Data Base Management System and the technology of database access used for the administration and management of teaching resources in the modem long-distance education. In accQrdance with the concerned isomerism and distributivity of the database system in the long-distance education, and variety of database inter-connectivity technology, we law lessons from the successful application in TCP/IP communication protocol, and adapt to use the Layer thought to realize the share of distributive isomeric database information. In view of the above mentioned ideas, this article makes the farther research about the Layer Architecture and probes into the Layer designing principle and Agent Oriented Model (AOM), and then raises the abstract model of the Layer Agent Structure. After comparing the database access technique in different stages, this article raises the Education Resources Agent Server (ERAServer) model on the basis of Layer Agent Structure, and supplys the architecture of ERAServer, and then describing minutely the different components. Finally, the article gives the work flow of ERAServer model, and uses the design technique of ActiveX application server, Object Oriented Design and ODBC API progr8mming technology, then finishes the design of ERAServer model. ERAServer has the effect that can shield the complex of details of back databaseand realize the share of the information of multi database distributed in differentgeograPhical sitUations, and suPply a good Application PrograInming Ini6thee ofDatabase Access to the client aPplications, and it is very trAnsplanable. So the raisingof the model is reasonable and realistic.. With the constam development of information technology and high-newtechnology' the manufacture technology of Courseware will have changes, and DataBase Management System and database access technology used for the administrationand management of resources will constantly weed through the old to bring forth thenew The system model and system functions wilI become perfect to adaPt to therequiremeats, and becomes the uniform managing platform of the netWork educationfCsources.
