Abstract: In one embodiment, a method receives a query for analyzing data in a database. The query includes a first level calculation that is performed before a second level calculation. When an operator associated with the first level calculation is present in the query, the method performs: calculating the first level calculation by removing group by information for a reference characteristic for the first level calculation to determine a first level calculation result and calculating the second level calculation using the first level calculation result using the group by information for the reference characteristic to determine a second level calculation result, wherein the group by in the second level calculation combines groups of rows in a database table of the database that have the same content in their specified columns.

Abstract: A method for producing a contoured ring rolling product for a rotating application from a ring blank, with a ring rolling machine controlled in a process-monitored manner. At least one process window, extending over the rolling time, is defined in relation to preselected process parameters for the specific product on the basis of calibrating specimens brought into their final form by the ring rolling machine. The process window(s) monitored during the process is/are determined by the process parameters of calibrating specimens which produced rolled products meeting the requirements demanded of the ring rolling product. The preselected process parameters comprise at least two of ring growing rate, axial rolling force, radial rolling force, rolling time, and ring blank temperature.

Abstract: In one embodiment, a method receives a query for analyzing data in a database. The method then determines a constant in the query and determines an operator applied to the constant in the query. The operator explicitly controls a behavior of the constant. The constant is represented as a scalar representation in the query instead of as a vectorial representation where the constant would have been used as the vectorial representation without the use of the operator due to a rule governing use of constants. Then, the method performs a calculation for the query to determine a query result using the constant as the scalar representation.

Abstract: In one embodiment, a method receives a query for analyzing data in a database. The query includes a first level calculation that is performed before a second level calculation. The method determines an operator in the query configured to explicitly remove group by information for a reference characteristic in the first level calculation where the group by information is specified for the reference characteristic in the second level calculation. The first level calculation is performed by removing the group by information for the reference characteristic for the first level calculation to determine a first level calculation result and the second level calculation is performed using the first level calculation result using the group by information for the reference characteristic to determine a second level calculation result.
