Performance Evaluation of Post-Relational Database in Hospital Information Systems

Hospital Information Systems (HIS) based on relational database show more and more shortcomings, such as low response speed, high maintenance charge etc. The post-relational database Cache, using multidimensional array and bitmap index techniques, shows faster response speed, lower hardware costs and routine maintenance than relational databases. In this paper, we compare the performance of relational databases with that of post-relational databases used in Hospital Information System. We select Cache as an example of post-relational databases, and Oracle of relational databases in the comparison test. We take three steps to compare the two databases which are based on Hospital Information System data: query test, append test and mixed test. The results prove that the post-relational database Cache performs better than the relational database Oracle in Hospital Information System.
