METHOD FOR RETRIEVING DATA OBJECT BASED ON SPATIAL-TEMPORAL DATABASE

摘要

Disclosed is a method for retrieving a data object based on a spatial-temporal database, the method being performing retrieval based on a management model category of a management object and a spatial attribute and/or a time attribute after modelling an object to be managed, so as to determine a running status of the management object, and the steps are as follows: modelling the management object with respect to a time status and a spatial status of the object to be managed; setting, according to a management model of the object to be managed, a specific attribute, described by means of a natural language, of the object to be managed; and performing retrieval based on the management model category of the management object and the spatial attribute and/or the time attribute that are/is defined by means of modelling and described by means of the natural language, so as to determine the running status of the management object. The method describes data information about production, monitoring and management by means of three periods of time, i.e. history, real-time and plans. A user only needs to use spatial-temporal meta-language to learn about a spatial-temporal running status of a management object by means of retrieval, wherein same not only saves on computer content, but also facilitates management.
