STORAGE MANAGEMENT ISSUES FOR HIGH PERFORMANCE DATABASE VISUALIZATION by

Database visualization helps the end users extract useful information from database by using visualization techniques. The problem to be solved by database visualization is to find a mapping between high-dimensional spaces that exists in the database and the two-dimensional space that exists on the computer screen. This thesis uses Java data model as an intermediate model to bridge the gap between database and visualization data models. The technology infrastructure is composed of the latest Java technology. The Java Data Object (JDO) interface serves as a mapping between storage and Java object. The distributed architecture is based on the Remote Method Invocation (RMI) and service looking up is performed with the Java Naming and Directory Interface (JNDI). The final visualization is realized with Java3D. Two sample runs for the visualization of protein-protein interaction and the visualization of computer network prove the novel approach of database visualization with Java data model is feasible. Powered by the architecture provide by this thesis, it is possible for new data arrived in storage becoming knowledge quickly.
