Learning Objects, Object-Oriented Database Applications
This paper presents initial work in the design of a National Learning Objects Repository for Cyprus (NLORC). The NLORC will provide a web-based application allowing indexing, uploading and downloading of e-learning resources, creation and modification of Learning Objects (LOs) and querying the repository. This paper presents a simple model that will underpin the development of the NLORC. The model caters for the creation, storage and manipulation of LOs. After careful consideration and studying of the existing Learning Objects Metadata Standards, it has been decided that the NLORC application should be developed using a database system supporting object-orientation and temporal database features. As a result of this, the model presented herein suggests an object-oriented database structure to form a basis for the application. The database structure caters for the relation property of LOs (defined in most of the Learning Objects Metadata Standards). The proposed database structure caters for the storage of these objects, keeping a record of the relations between them and allowing their retrieval and manipulation.
