Abstract: A system and method for analyzing the data flow of a database query. The database query contains a plurality of query conditions that are used to filter data records of a database. At least one query condition is identified from the plurality of query conditions in the database query. The database is queried based upon the identified query condition. At least one results characteristic is determined that is associated with the query of the database with the identified query condition. The results characteristic is used to analyze the identified query condition.

Abstract: A computer-implemented method and system for mapping a computer data input column to a computer data output column. The input column and the output column have attributes. Information is received about at least one of the input column attributes and at least one of the output column attributes. At least one of the input column attributes is compared to at least one of the output column attributes to determine a likelihood ranking for mapping the input column to the output column. The likelihood ranking is between zero and one-hundred percent certain. The decision whether to map the input column to the output column is based upon the likelihood ranking.

Abstract: A device allowing one person to easily and conveniently load a kayak or similar article onto an automobile's roof rack. The device comprises several freely rotating rollers oriented in a "V" configuration by rigid struts attached to a crossmember. Padded feet flexibly mounted to vertical stanchions extending downward from the crossmember support the rear most portion of the loading device. An attachment mechanism extends forward from the crossmember which securly latches the loading device onto a vehicle's roof rack crossbar. Loading a kayak requires first positioning a kayak's bow into the vertex of the rollers. The stern of the kayak is then pushed upwardly and forwardly along the rollers onto the automobile's roof rack. The device is removed from the automobile's roof rack after the kayak is loaded.
