Abstract: A electronic device support provides a platform upon which an electronic device may be temporarily placed to prevent damage and/or contamination of the electronic device. The device has a rectangular bed sized to receive and secure the electronic device. The rectangular bed has a first side has a peripheral wall to enclose the electronic device, the peripheral wall having a length portion and a width portion. The length portion has a pair of opposite facing grab slots and the width portion has a pair of opposite facing charge slots. A socket member is attached to the second side of the rectangular bed. An arcuate arm member has a first end with male member configured to be received within the socket member. The arcuate arm member has a second end which may either be configured as a clip member or the second end may be attached to a wall-mountable face plate.

Abstract: A database engine receives a database query from a client. The database engine parses the database query to build a query operator tree that includes a plurality of query operators. The database engine performs one or more optimization passes on the query operator tree, including a deduplication optimization pass, to form an optimized execution plan. The deduplication optimization pass includes: creating a list of query operators via a first traversal of the query operator tree, determining a first query operator that is equivalent to a second query operator, based on a hash map, via a second traversal of the query operator tree, and substituting, via a third traversal of the query operator tree, the second query operator with a tree node that links to the first query operator. The database engine executes the optimized execution plan to retrieve a result set from the database, and returns the result set.
