Abstract: According to one embodiment of the present invention, a system processes a database query, and comprises a computer system including at least one processor. The system identifies one or more expressions within the database query utilizing a database object with value masking. Masking requirements are determined for each identified expression and the database object utilized by that identified expression is replicated to provide masked and actual versions of that database object in response to the masking requirements for that expression including masked values and actual values of that database object. The value masking of the database object is applied to the identified expressions within the database query based on the determined masking requirements to produce search results with masked values for the database query. Embodiments of the present invention further include a method and computer program product for processing a database query in substantially the same manner described above.

Abstract: Motion is departed to the water in water beds by periodically lifting a region of the lower surface of the water bed mattress, said region being contained somewhere within the outer margins of the water bed. A water motion that is more uniform and more acceptable in practical applications is provided by lifting a region at least one of whose margins is not parallel with the plane of any of the sides of the water bed mattress. In a preferred embodiment, it is a triangular section of the bottom of the water bed that is lifted, and the lifting is accomplished by tilting that triangular section upwardly toward the upper wall of the apparatus and by accomplishing that tilting from the apex of the triangular region. In a refinement of the action, a means is provided for adjusting the lifting action in frequency or degree to achieve a relationship with the natural resonant frequency of water movement that produces a pleasant bed motion.
