Abstract: A computerized query optimization methodology, computer program product, and electronic device for intelligently optimizing the lookup of graphed data in a data store or distributed across a plurality of databases is disclosed. The method defines an initial metafuture including a plurality of attributes starting with initial data references to determine a starting list of data reference dependencies with respect to metafuture construction functions. In response to a query, a processor initiates a recursive graph traversal of nodes in a graph starting with the initial metafuture as a root node. At each step of the graph traversal, if the metafuture contains an answer, then the process traverses the graph laterally. If there are no further siblings, then the processor initiates a vertical traversal.

Abstract: A line power cord voltage-magnitude adaptor is described herein. In a particular embodiment of the present invention, the power plug, line cord, and adaptor plug are pre-assembled as one component of the electrical equipment system; various voltage requirements can thus be prepared-for, whereby the equipment need not be altered, regardless of the eventual market for the equipment. The present invention can be used with virtually all kinds of electrical equipment energized by AC power, including computer systems.
