A Data Stream Management System (DSMS) is a set of computer programs that controls the maintenance and querying of data in data streams.[1] The use of a DSMS to manage a data stream is roughly analogous to the use of a Database Management System (DBMS) to manage a conventional database.[1]

A key feature of a DSMS is the ability to execute a continuous query against a data stream. A conventional database query executes once and returns a set of results for a given point in time. In contrast, a continuous query continues to execute over time, as new data enters the stream. The results of the continuous query are updated as new data appears.[2]
