Problems solved by technology

[0005] The spatial databases currently established that contain basic geographic information require a large amount of data collection and consultation and database modeling processes. The auxiliary establishment of spatial databases is mostly a manual process, which not only consumes a lot of manpowe

Abstract

The invention provides an auxiliary design system and a design method for a spatial database under the support of a knowledge base. The auxiliary design system comprises a knowledge base component used for forming the knowledge base designed by an auxiliary spatial database according to the related rules of building the database and forming a spatial database template according to the defined rules in the knowledge base; a structural design component of a database used for setting various layers of contents and the corresponding relation of the spatial database based on the spatial database template according to the requirements of building the database, so as to form the structure model of the spatial database; an establishing component of the structure model of the spatial database used for controlling formation of the structure model of the spatial database according to various layers of contents and the corresponding relation of the spatial database set by the structural design component of the database and used for the auxiliary design of the spatial database; and an output component of the spatial database used for outputting the spatial database model obtained in the form of database files and generating documents of a spatial database building scheme.

Description

technical field [0001] The invention relates to a method for designing a spatial database supported by a knowledge base and an auxiliary design system for a spatial database supported by the knowledge base using the method. More precisely, the present invention relates to a spatial database aided design system supported by knowledge bases supported by knowledge bases formed by rules, norms, and standards for the hierarchical structure of spatial databases and the design methods for the contents of each level of spatial databases. . Background technique [0002] The rapid development of space technology and information technology has promoted the informatization of the global society. On the one hand, the development of the information society puts forward a strong demand for geospatial data, and on the other hand, it strongly promotes the construction and development of spatial data infrastructure. [0003] Spatial database design is the basis of establishing database and ...
