분산데이터베이스를 이용한 메타데이터 기반실과 교수학습자료 공유 시스템 설계

Abstract

A lot of learning objects have been distributed to schools, but they are not fully utilized because many teachers do not know where the data are and how to use them. Furthermore, the internet search engines produce large amount of data most of which are of no use. Thus, it is needed to develop an efficient method of finding data necessary for instruction and learning. In this study, a learning objects management system is constructed that utilizes these unused servers by connecting distributed databases using JDBC, which is a technology for distributed database. In addition, we developed an learning objects sharing function based on a metadata standard that we revised using the data collected from Sharable Content Object Reference Model(SCORM), a metadata standard from Korea Education & Research Information Service(KERIS).
