A servomotor controller provides nut runner and other functions in a set of stackable modules. Extended-function modules can be added into and removed from the stack as needed. Destacking of closely spaced, wall-mounted controllers can be performed without demounting. Module assemblies are dripproof. Multiple sizes of nutrunner driver electronics and multiple keyboard and display options can be selected. A reprogrammable central processor can identify newly installed or removed features within a controller and reconfigure itself F accordingly. Stackable modules include Ethernet(®, multiple-bit I / O, and proprietary interfaces for many industries. The other modules communicate with the processor module via a backplaneless bus architecture. The central processor supports master / satellite group operation, whereby one controller unit can command multiple others, and whereby a higher-level system can command multiple controllers or multiple master / satellite controller groups.

A database system providing improved methods for optimization and execution of queries aggregating information from multiple database tables is described. The improved method breaks serial operations into a group of child operations that can be individually optimized and processed in parallel. A query including a grouping operator over a union node is split by pushing the grouping operation down into each input arm of the union node. Specifically, grouping operators are inserted into each child arm of qualifying union nodes, enabling separate physical database tables to be summarized in parallel. Each of the child grouping operators concurrently groups data and generates summary results in parallel, taking advantage of capabilities of available parallel processing hardware. The aggregate operators of the original master grouping operator are modified to accept and correctly synthesize sub-aggregated results generated by each of the child grouping operators. The method also enables individual optimization of operations on each database table, including use of advantageous index-only execution plans.

The present invention provides a method for hierarchically decomposing a visual or audio object within an animation into plurality of objects which can be individually edited to achieve particular animation effects. For example, a graphical object may be decomposed into a plurality of graphical sub-objects, each of which is inherits an anchor point from the original object, or is given an original anchor point distinct from the original object. Each sub-object also includes a relative position for the sub-object relative to the anchor point. The path of the anchor point is combined with relative positions of the sub-objects to produce an animation for the object as a whole. This decomposition technique can greatly increase computational efficiency of an animation. It also provides for inheritance of attributes between objects and descendent sub-objects. The objects may support functions, or behaviors, such as morphing or motion blurring. The present invention additionally provides a flexible grouping operation to facilitate modifications to a group of objects. When a first type of modification is made to an attribute of an object in a group, this change is applied to corresponding attributes of other objects in the group. When a second type of modification is made to an attribute of an object in a group, the change only applies to the selected object or objects, and not to other objects in the group. The present invention allows objects to be manipulated on servers which are connected to a display via the Internet.

The invention discloses a multi-dimensional OLAP (On Line Analytical Processing) inquiry processing method facing a column storage data warehouse. In the multi-dimensional OLAP inquiry processing method, the OLAP inquiry is decomposed into a bitmap filtering operation, a grouping operation and an aggregation operation. In the bitmap filtering operation, firstly, the predication is executed on a dimension table and a predicate vector bitmap is generated; and a connection operation is converted into a direct dimension table record access operation by surrogate key address mapping so as to implement access according to the positions. In the grouping operation, the pre-generation of grouping units is carried out on fact table records which meet the filtering conditions according to grouping attributes in an SQL (Structured Query Language) command and increasing IDs (identity) are distributed. In the aggregation operation, the grouping aggregation calculation which is carried out according to a grouping item of a grouping filtering vector of a fact table is implemented by carrying out column scanning on the metric attribute of the fact table for once. According to the invention, all OLAP processing tasks can be completed only by carrying out column scanning on the fact table for once, so that the cost of repeatedly scanning is avoided.
