A High Performance Solution for Automated Computer Examination Systems

In this paper ire present an effective and practical approach for developing high-performance, scalable, and manageable automated computer examination systems (ACES). The proposed solution employs the XML technology) to naturally represent and efficiently manipulate the semi-structured data of test libraries, performs the most complex computational tasks via SQLCLR objects that reside in the server-side processes, and therefore reduces the network traffic and improves system performance vastly. Our approach has been successfully applied in several real-world examination systems, and has demonstrated its significant contribution to the effectiveness and efficiency of computer-based test delivery and management.
