Abstract: According to an embodiment of the present invention, a system provides a graph that identifies data mapping rules for a data transformation type and comprises: a display interface configured to present a plurality of distinct node types, each with a distinct location and is displayed at corresponding a first display location, a second display location and a third display location on the display surface, a first distinct node type is a pure data type with one or more value output ports; a second distinct node type is a data mapping type with one or more value input ports and at least one output port; and a third distinct node type is a sequence instruction type with one or more stream input ports and at least one output data transform port; a computer processor that generates a rules configuration representing a graph construct; and a memory that stores the rules configuration.
