Educational Resources Database Management System Design And Realization

China Education Resources Library building has made some achievements, online teaching resources is very large, due to lack of education, information technology-related technical standards, and many educational resources, although broadly consistent with the content and form, but the building standards, technical applications and databases using The do not just like, we created the process in use can not be shared, so the building of repeated resource pool. Various educational resources systems each category, only in a small scale to achieve resource sharing, can not do in a wide range of resources within the full use of each other. Elimination of these phenomena, the National Educational Technology Standards Committee (CETLSC) study and formulate a number of related standards (CELTS standard), the CETLS standard applies to the construction of educational resource library, so that the construction of the various educational resource library has certain standard to follow. Have a very important practical significance and theoretical value.This thesis 's main task is by analyzing the current status of educational resources management system is proposed to the current heterogeneous educational resources sharing programs, namely: a unified classification of educational resources, using XML language to describe, after finishing off the resources of the system Users can not consider the physical storage to retrieve resources to learn. To achieve a true sharing of resources utilization.This thesis studies the state Department of Education Learning Technology Standards Committee issued CETLS standards, as the guidance, in strict accordance with standards defined in the instructions, develop an educational resource library management system. The resource file metadata data model is based on examples of XML technology, the development of an educational resource management systems, thereby enhancing the efficiency of the management of educational resources to achieve educational and teaching resources can be shared.
