TEMPORAL SUMMARY TABLE MANAGEMENT SYSTEM AND ITS GRAPHIC INTERFACE

There are many applications of databases, such as CAD/CAM, Office Automation, and Scientific/Statistical applications, that require not only current data but also past data. For such kind of applications, temporal databases maintain all evolution history of data. The history of data will be frequently used to analyze past and current data and to forecast the future. In this paper, we implement a system supporting statistical analysis of temporal databases. The system provides summary tables on temporal databases which are tabular representation of summary statistics obtained from source databases. The system also provides a graphic user interface displaying the data of summary tables in graphical forms such as histograms, graphs, and diagrams. These forms are useful for statistical analysis thus can help users to make a decision.
