This paper presents a theoretical model and a pilot implementation of the National Learning Objects Repository for Cyprus (NLORC). The NLORC provides a web-based application allowing indexing, uploading and downloading of e-learning resources, creation and modification of Learning Objects (LOs) and querying. Two alternative database designs are considered and briefly discussed herein. The first design is a relational database design whereas the second design is an object-oriented one. The implementation described herein utilizes concepts from both designs. Although the relational database design is adopted, the choice of implementing the NLORC using Ruby on Rails framework provides the functionality of object-oriented implementation. Thus, the main contribution of this paper is the novel theoretical model and the system implementation, which enjoys the advantages emanating from the utilization of object-oriented features. The proposed database application has been designed based on existing LO Metadata Standards and a survey we carried out amongst University professors in Cyprus. The results of this survey are also presented in this paper.
