Abstract
A method of transforming relational queries of a database into on a data processing system includes receiving a series of relational queries, transforming first parts of the queries into a continuous query embodied as a streaming application, sending parameters in second parts of the queries in the series to the streaming application as a data stream, and executing the continuous query based on the received data stream to generate query results for the series of relational queries. Each query in the series includes a first part and a second part. The first parts are a pattern common to all the queries in the series and the second parts each have one or more parameters that are not common to all of the queries in the series.
