16. The method of claim 1 , wherein the executing that implements the data network comprises: classifying whether each of a plurality of objects of the data network belongs to the class designated by the domain of the process step; performing the algorithm on each of the plurality of objects that belong to the class; automatically generating a second class that is part of the class network, wherein the domain designates the second class instead of the class; and performing the algorithm on each object of the plurality of objects that belong to the second class.
1. A method comprising: in a specification mode: specifying a class network having a class, wherein a membership function defines a likelihood that an object of a data network belongs to the class; specifying a process step having a domain and an algorithm, wherein the domain designates the class, and wherein the process step is part of a process hierarchy; specifying a link type that defines a relation between the class and the object; in an execution mode: acquiring table data values; and executing the class network and the process hierarchy on a computer that implements the data network by generating the object of the data network and by selectively linking selected table data values to the object according to the class network and the process hierarchy.
