Abstract
A method for retrieving data objects based on a spatial-temporal database includes modeling a to-be-managed object in consideration of temporal and spatial statuses of the to-be-managed object; setting specific attributes of the to-be-managed object that are expressed in a natural language according to resultant management models of the managed object; and performing retrieval based on types of the management models of the managed objects and a spatial and/or temporal attribute that is expressed in the natural language and defined by the models so as to determine the operational status of the to-be-managed object. Since data information about monitoring and management of production is described over three temporal periods that are associated to historical data, real-time data and plan data, a user can know spatial-temporal operational statuses of the to-be-managed object by performing retrieval using a spatial-temporal metalanguage, making data management simple and saving storage in computers.
