Abstract: A computer-implemented method is for performing a process having a plurality of work steps using one or more computing units. The method includes defining a process having a plurality of work steps. Each work step requires one or more defined inputs, and each work step generates one or more defined outputs. The outputs of some work steps are used as inputs of other work steps. The method further includes checking whether all required inputs can be generated by the process, and ordering the work steps according to the dependencies resulting from the inputs and the outputs, when the checking determines that all required inputs can be generated by the process. The method also includes instantiating the ordered work steps, and performing the instantiated work steps by one or more computing units.

Abstract: A method is for validating a data set in a distributed database system in which the data set is stored distributedly on computers of the distributed database system. The method includes sending a request to one of the computers by a central computer. The request has a command to check for a given criterion of a partial data set of the data set on the computer to which the request was sent.

Abstract: A method for extracting data from a data memory. The method includes: providing data; storing the data in a data memory; developing an optimal extraction strategy based on a current use case and/or available resources; extracting data from the data memory based on the optimal extraction strategy; and providing the extracted data.
