Analysis system and method for analyzing continuous queries for data streams

摘要

The present invention concerns an analysis system (1) for analyzing at least one continuous query (100) for at least one input data stream (200), wherein the at least one input data stream (200) comprises a sequence of events captured by at least one sensor and wherein the debugging system comprises:a. an analyzer (10), adapted for executing the at least one continuous query (100) and at least one modified continuous query (100') on the at least one input data stream (200), for comparing at least one output data stream (300) produced by the at least one continuous query (100) with at least one second output data stream (300') produced by the at least one modified continuous query (100') and for indicating at least one difference between the at least one output data stream (300) and the at least one second output data stream (300');b. wherein the analyzer (10) is adapted for synchronizing the execution of the at least one continuous query (100) and the at least one modified continuous query (100').
