An oxide catalyst is formed by vaporizing a quantity of at least one precursor material or catalyst material thereby forming a vapor cloud. The first electronic device includes an evaluation unit adapted to switch the first electronic device from an operating state to at least one energy saving state and vice-versa, and a standard interface for connecting the first electronic device to a second electronic device. A query having a Cartesian product is implemented to join the UDT table and data table for invoking behavior of the UDT and generating a resultant data table without increasing cardinality thereof.
