Multi-Dimensional OLAP Query Processing Method Oriented to Column Store Data Warehouse
ActiveUS20130275365A1Improve I/O performanceReduce complexityDigital data processing detailsMulti-dimensional databasesOne passSurrogate key
A multi-dimensional OLAP query processing method oriented to a column store data warehouse is described. With this method, an OLAP query is divided into a bitmap filtering operation, a group-by operation and an aggregate operation. In the bitmap filtering operation, a predicate is first executed on a dimension table to generate a predicate vector bitmap, and a join operation is converted, through address mapping of a surrogate key, into a direct dimension table tuple access operation; in the group-by operation, a fact table tuple satisfying a filtering condition is pre-generated into a group-by unit according to a group-by attribute in an SQL command and is allocated with an increasing ID; and in the aggregate operation, group-by aggregate calculation is performed according to a group item of a fact table filtering group-by vector through one-pass column scan on a fact table measure attribute.

The present invention is a system for and method of providing instruction sequence compounding by (1) the virtual machine monitor's (VMM) looking ahead when an initial trap (exception) event occurs and recognizing traps within successive nearby instructions, combining and virtually executing the effects of multiple instructions while remaining inside the VMM's trap handler, and thereby minimizing the number of individual traps that would otherwise occur at each instruction and / or (2) the VMM's looking ahead when an initial context switch event occurs and recognizing context switches within successive nearby instructions, virtually combining the effects of multiple instructions and handing off this combined instruction to the host operating system, and thereby minimizing the number of individual context switches that would otherwise occur at each instruction. As a result, the number of processor cycles is reduced for exception handling and context switching in a virtual machine environment.

Data Reorganization through Hardware-Supported Intermediate Addresses
InactiveUS20110238946A1Improve performanceImprove efficiencyMemory adressing/allocation/relocationMicro-instruction address formationApplication softwareData reorganization
A virtual address scheme for improving performance and efficiency of memory accesses of sparsely-stored data items in a cached memory system is disclosed. In a preferred embodiment of the present invention, a special address translation unit is used to translate sets of non-contiguous addresses in real memory into contiguous blocks of addresses in an “intermediate address space.” This intermediate address space is a fictitious or “virtual” address space, but is distinguishable from the virtual address space visible to application programs, and in user-level memory operations, effective addresses seen / manipulated by application programs are translated into intermediate addresses by an additional address translation unit for memory caching purposes. This scheme allows non-contiguous data items in memory to be assembled into contiguous cache lines for more efficient caching / access (due to the perceived spatial proximity of the data from the perspective of the processor).

Each row of data in a first database table is associated with a plurality of time thresholds that indicate, respectively, when a given row of data in the first table is current, stale, or expired. When a given row of data expires, that row is moved from the first table to a second database table that stores expired data. One of the time thresholds indicates a predetermined amount of time that the expired data will be maintained in the second table. Once that threshold expires, that row of data is deleted from the second table. Until then, however, a user may issue queries to access the expired data along with the current data and the stale data.
