Abstract: Methods, apparatus and systems for processing of code that includes key fields having surrogate and extends relationships are described. In some embodiments, a method includes receiving a pattern language code having definitions of a number of classes, wherein a definition of a first class of the number of classes comprises a reference to a field. The method also includes compiling the pattern language code to generate an object code, wherein the compiling comprises validating that the field is defined with a context of the first class. The context includes a second class of the number of classes that has a surrogate relationship with the first class.

Abstract: Various embodiments provide one or more of systems, methods, software, and data structures that include action request definitions that may be linked to a workflow process. Upon submission of an action request from an action request definition, an action request record may be created as a function of an action request definition and passed through a linked workflow process. The action request record may be modified, approved, or rejected. If approved, a process defined within the action request definition may cause a data change as a function of action request data. Action request records may be persisted, in some embodiments, to provide an action request audit trail.
