ABSTRACT A prototype of a temporal database management system was built by extending Ingres. It supports the temporal query language TQuel, a superset of Quel, handling four types of database static, rollback, historical and temporal. A benchmark set of queries was run to study the performance of the prototype on the four types of databases. We analyze the results of the benchmark, and identify major factors that have the greatest impact on the performance of the system. We also discuss several mechanisms to address the performance bottlenecks we encountered.

    ABSTRACT: Temporal geographic information system (t-GIS) is a kind of computer information system that can display, process and analyze the micro-format distribution of temporalspatial information of real world. It includes both spatial geographic information and temporal information, and can analyze both the static geographic information and the dynamic geographic information. Three models based on t-GIS for environment dynamics, namely, the mechanism method, the experience method and the mixed method are given. t-GIS based on the environment dynamic model has more new functions than traditional GIS, such as fast I/O, inquiry, static/dynamic display and visible analysis of spatial and temporal sequence information, especially it can display the image of the evolution in the past, current and future environment through the extrapolation method within its defining region. The velocity for analogue display can be accelerated by setting up time-varying-area-function for position and attribute. Dynamic environmental information analysis systems based on t-GIS are applicable to almost all the fields related to management, display and analysis of local environmental dynamic information. For this reason, some considerations to construct distinct information systems have been enumerated in this paper, such as, the analysis information system for terrain evolution, the analysis information system for the condition of water and fertilizer of farmland, analysis and the evaluation information system for ecological environment, and the analysis information system for distribution changes of population of China, etc.
