Visualization of critical properties of databases of information systems

This paper is focused on a problematic about three-dimensional visualizations of data. The main task of visualization is to provide information to the user much more effective than raw data. We present an overview of current research in this area. Also we present our visualization tool for visualizing of critical properties of databases in the three-dimensional system. By measuring of critical properties we are gaining important information about properties and behavior of the data system in the real operation. Then we have various possibilities how to propose various changes, improvements in the next design. The visualization tool provides enough knowledge to help interactively to implement successfully all needed changes in the system. This ability realized by integration of critical knowledge into the executable auto-reflexive software architecture.
