Abstract: Database queries for retrieving data from database tables, that do not impose any constraints on the data to be retrieved, result in Cartesian product joins. Such unconstrained database queries when executed impose a significant load on resources, take a long time to execute, and may produce inaccurate and misleading results. Functionality can be implemented to reduce the amount of data retrieved by constraining database queries resulting in Cartesian product joins before they are executed. This can be done by leveraging referential constraints that depict relationships between the tables to be joined to limit the results produced by executing the Cartesian product join. Automatically detecting and preventing execution of Cartesian product joins by leveraging the referential constraints can reduce the processing load on the machine, reduce the time spent in executing the database query, minimize the number of query results, and prevent inaccurate results from being displayed.

Abstract: A controllable hydraulic oscillating slide machine includes an inner rotor arranged in a housing and having cylindrical recesses. A bearing is formed in the housing, in which a co-rotating outer rotor is mounted eccentrically to the inner rotor, the outer rotor having several pivotably suspended slide drivers that engage into the recesses of the inner rotor for rotationally driving the outer rotor by way of the inner rotor and form modifiable chambers. The slide drivers may each be coupled to a piston that is guided in a respective associated recess. A pressure level different from that in the chambers between the inner and the outer rotor may be set in the chambers delimited by the recesses and the associated pistons so that two different pressure levels may be generated and two different consumers can be supplied using the oscillating slide machine.
