摘要: 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.

摘要: 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.

摘要: The present invention relates to leg extension assembly comprising an outer sleeve member having a box leg member disposed therein, a telescopically collapsible inner leg member slidably mounted within said sleeve member, means for connecting said box leg member to said inner leg member, said means including a spring element which biases the inner leg member away from the box leg, and locking means for locking said inner leg at a selected extended length. The leg extension assembly may be incorporated into a leg element, or in the alternative, may be attached or otherwise affixed to an existing leg, such as an existing leg of, for example, a ladder, scaffold, sawhorse, table or chair by any means well known in the art.
