A Framework to Support Schema Matching in E-learning

摘要

Interoperability between eLearning systems can be achieved through adoption of standards. However, the differences in the data models provided by eLearning systems and learning standards mean that mediation is required to achieve interoperability. With the pervasiveness of relational databases and XML in eLearning systems, we propose a mediation framework that maps between the relational database schemas in eLearning systems and eLearning standards defined in XML Schema. This framework consists of a Schema Matcher Module, a Translation Module and a Mapper Tool. All three modules integrate to provide mapping of schemas and translation of data between the two sources for eLearning systems.
