Abstract

This paper presents the database application and the system architecture of a National Learning Objects Repository for Cyprus (NLORC). The main contribution of this paper is the novel database application, which has been developed using the object-relational database system Oracle lOg and thus enjoys the advantages emanating from the utilization of object-oriented features. The NLORC implements a typical three-tier architecture. The core part of the NLORC is a Database tier, accessed and managed by means of the Application Server. The front-end of the system is built on the WEB servers. Another prominent part of the system is the NLORC storage. The NLORC storage allows storing a wide range of LO implementations covering the most popular ones. For this reason the system also includes the file server, Apache WEB server, as well as other database servers. Thus, the NLORC storage can be used for storing various types of interactive and non-interactive LOs.
