Filed:

Feb 25, 2005

Appl. No.:

11/067285

Inventors:

Allen Clark - Woodinville WA, US
Bryan MacFarlane - Duvall WA, US
Xiongjian Fu - Sammamish WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 17/30

US Classification:

707204000

Abstract:

In one embodiment, a method an apparatus for managing a system comprising at least one operational data store and a data warehouse that is associated with at least some of the data in the operational data set, comprising automatically updating the schema of the data warehouse to reflect a change to the schema of the at least one operational data store. In a further embodiment, a method and apparatus for requiring that a designer of a database system provide metadata that defines changes to be made to a data warehouse in response to a modification of an area in an operational store. In another embodiment, a method and apparatus for detecting schema changes to an operational store, so that appropriate action may be taken in a data warehouse. In a further embodiment, a method and apparatus for implementing changes to a data warehouse schema, comprising the execution of one or more lower level calls to appropriate APIs to modify the schemas of both a relational database and an OLAP database.

International Classification:

G11B 1700
G11B 5012
G11B 2504

US Classification:

360 97

Abstract:

A drive belt release mechanism for magnetic disk drives for disengaging a drive belt from and engaging a drive belt onto a spindle drive pulley. To disengage the belt, the mechanism lifts the belt from the drive pulley and simultaneously permits the drive motor to pivot to relieve the tension in the drive belt. To engage the belt, the mechanism seats the belt on the pulley and forces the motor to a drive position which yields the desired drive tension in the belt. The mechanism is completely mechanical and manually operable.

Inventors:

Mark Frederick Amberg - Manhattan Missions, SG
Allen Walter Clark - Colorado Springs CO
Benjamin Alma Young - Colorado Springs CO

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

H01R 922

US Classification:

439717

Abstract:

Racks of modules especially useful for retaining disk drives, tape drives, controllers, computers and the like are fabricated via use of tower building blocks. Each block contains a latch arrangement for securing it to another block, a base unit or a cap unit with the latch effecting interlocking of the blocks so as to form a sturdy assembled structure. Power and/or electrical communication lines are provided in each block with power passing through one vertical array of blocks and electrical communications passing through the other so as to reduce the need for shielding one from the other. An arrangement of alignment pins and mating receptacle holes in conjunction with selected placement of sliding latch elements can facilitate proper coupling of blocks which have similar electrical path boards therein. Spring elements contained in the latch configuration can include biasing to overcome tolerance build-up and plastic creep from repeated and long term usage.
