摘要： 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.

摘要： A method and apparatus for implementing transactional memory (TM). The method includes: allocating a hardware-based transaction footprint recorder to the transaction, for recording footprints of the transaction when a transaction is begun; determining that the transaction is to be switched out; and switching out the transaction, where the footprints of the switched-out transaction are still kept in the hardware-based transaction footprint recorder. According to the present invention, transaction switching is supported by TM, and the cost of conflict detection between an active transaction and a switched-out transaction is greatly reduced since the footprints of the switched-out transaction are still kept in the hardware-based transaction footprint recorder.
