    摘要： A structured query language (SQL) grouping and aggregation system and method that incorporates hash-based techniques, several overflow handling strategies and statistics-based process-selection criteria. The method can execute SQL group-by queries on distributed database tables or tables stored locally to the database management system (DBMS) processor executing the grouping method. Hash-based techniques allow groupings and aggregates to be generated on the fly through the use of partial aggregates maintained in primary memory. Where primary memory is limited, groups and aggregates are still generated for as many groups as can be maintained in primary memory, while various overflow procedures are provided for buffering ungrouped data and writing that data to an overflow disk file for later processing. In one overflow procedure, raw data from groups that cannot be aggregated in primary memory are buffered then written to the overflow disk file. In a second overflow procedure, ungroupable raw data is formatted the same as data being aggregated in the group table, buffered, and then written to the overflow file. In a third overflow procedure, ungroupable raw data is partially aggregated in an output buffer maintained in primary memory before being written to the overflow file maintained in secondary memory. Database table statistics maintained by a cataloger are consulted to determine whether hash-based grouping or conventional sort based grouping should be used to execute a group-by query. The system is adaptable to running a grouping query against a partitioned database on distributed processors.

    摘要： There is provided a computer-executed method of freeing memory. One exemplary method comprises receiving a message from a user process. The message may specify a virtual address for a memory segment. The virtual address may be mapped to the memory segment. The memory segment may comprise a physical page. The method may further comprise identifying the physical page based on the virtual address. Additionally, the method may comprise freeing the physical page without unmapping the memory segment.

    摘要： A method and system to automate software testing using sniffer side and browser side recording and a toolbar interface are described. In one embodiment, a system tests programming code associated with a website and creates a first test case. In another embodiment, the system includes a testing device having a test interface to enable a user to initiate a first test case and to store a first HTML representation and a first XML representation of encrypted web pages viewed during the first test case. In another embodiment, the system includes a sniffer server that operates as a proxy server for the website and stores a second HTML representation and a second XML representation of unencrypted web pages viewed during the first test case. The system may include a hosting server that hosts the website and receives the first and the second HTML and XML representations from the testing device and the sniffer server when the test case is terminated via the test interface.

    摘要： An automated method to align column values to proper byte boundaries for rapid scanning in a parallel processing database system. A table definition is received having a logical order of fields. The fields are re-ordered to create a physical order of fields. The physical order of fields has fixed length fields having a same byte alignment requirement positioned adjacent to each other in descending order from largest size to smallest size, and wherein a first fixed length field in the physical order is aligned on a proper byte boundary. Other embodiments, aspects and features are also disclosed.
