APPARATUS AND METHOD FOR PROCESSING CONTINUOUS QUERY

摘要

PURPOSE: A consecutive query process apparatus for processing time-space query through time-space information is provided to realize a situation deduction and application using an efficient sensor stream by implement a continuous query. CONSTITUTION: A continuous query processor(210) acquires an operator list composing the continuous query by parsing the continuous query. A stream converter(220) converts a sensor stream into context-aware data through a spatial operator, a temporal operator and time-space operator.
