  • Publication number: 20090157623
    Abstract: Techniques are described herein for supporting pipelining operations involving DML (Data manipulation Language) and query. In an embodiment, a DML operation is performed for the purpose of changing data in a database system from a first state to a second state. Before the data in the database system is changed by the DML operation, the DML operation has an in-memory representation of such data. In an embodiment, a subsequent query operation that logically depends on the data in the database system in the second state is granted access to the in-memory representation of such data in the second state before the data in the database system is changed by the DML operation to the second state. As a result, operations may be executed in a pipelined fashion with minimum blocking.

  • Publication number: 20080105891
    Abstract: According to one exemplary embodiment, a method for determining a self-heating free drain current in a transistor corresponding to a channel temperature not affected by a drain DC current includes measuring at least three unique drain currents of a transistor corresponding to at least three unique ambient temperatures. The method further includes determining at least three unique channel temperatures of the transistor corresponding to the at least three unique drain currents, thereby establishing a current-temperature relationship for the transistor. The method further includes determining the self-heating free drain current of the transistor utilizing the current-temperature relationship.

  • Patent number: 7222123
    Abstract: A method for performing multiple merge operations with a source data structure and a plurality of destination data structures, in which the source data structure is scanned one time in order to obtain source data that is then used for multiple merge operations. The source data is then used consecutively in order to merge the source data into the one or more destination data structures. Each merge is performed using the same scan of the source data structure and within the same execution of a database command.
