Space-time database administration method and system

Abstract

The invention discloses a spatiotemporal database management method, as well as a management system and a program product thereof. The spatiotemporal database management system comprises a data collection part, a spatiotemporal data association part and a spatiotemporal data management part, wherein, the data collection part is used to collect or receive the spatial information and the timing information about a geographical entity from external systems, and the produced and existed object timing information of the data are arranged; the spatiotemporal data association part is used to associate various data obtained from the data collection part with the object timing information, and store the association into a corresponding spatiotemporal data file, so as to express the evolution history of the geographical entity and predict the change of the geographical entity; the spatiotemporal data management part is used to respectively store the spatiotemporal data file produced by the spatiotemporal data association part according to the temporal information recorded by the timing information of the geographical entity and the evolution trend recorded by the spatial information of the geographical entity, so as to compose a spatiotemporal database.

Description

technical field [0001] The invention relates to a spatio-temporal database management method and a spatio-temporal database management system using the method. More precisely, the present invention relates to a spatio-temporal database management system that organically combines spatial information and time information of geographic entity objects to manage and apply geographic entity objects. Background technique [0002] The ever-changing space technology and information technology have promoted the informatization of the global society. The development of the information society, on the one hand, puts forward a strong demand for the current situation of geographic information; on the other hand, it strongly promotes the continuous updating of national basic geographic information, and generates a large amount of geographic historical data. Developed countries not only emphasize the current situation of maintaining geographic information, but also pay attention to preserv...

AI Technical Summary

Problems solved by technology

For example: as the amount of data increases in the time cube model, the operation of the cube will become more and more complicated, so that it will eventually become unprocessable; the storage of the sequence snapshot model has a large amount of data redundancy; ground state correction The model can greatly save the storage space of the computer, but it is difficult to deal with the spatial relationship between spatio-temporal objects at a given moment

The spatio-temporal composite model has low efficiency in the retrieval of the historical state of geographical entities and the reconstruction of the global state; the object-oriented model supports the modeling of spatio-temporal complex objects, but there is no consensus on the theoretical basis and implementation technology, and it is difficult to realize

Most of the existing models only focus on one aspect of the time domain and the space domain, and more studies are made on the logical level (conceptual model), which is not suitable for the design and implementation of spatio-temporal databases, and it is difficult to realize multi-type, massive spatio-temporal data storage, Management and Analysis
