| 主权项 | 1. A system for querying a database by a process of a computer, the system comprising: a non-transitory computer readable storage medium; a processor communicatively coupled to the computer readable storage medium; and a feature selection module communicatively coupled to the computer readable storage medium and the processor, wherein the feature selection module is configured to perform a method comprising: storing a spatio-temporal database in the computer readable storage medium, the spatio-temporal database including a time field; extracting data in a predetermined period from a current time from the spatio-temporal database; sorting the data by the time field; buffering the sorted data in a main memory; receiving a query including time; and outputting the data buffered on the basis of the time field as a spatio-temporal data stream. | ||
