A system, a method, and a computer program product for deriving target attribute values based on source attributes defined by a hierarchical data mode are disclosed. An attribute value derivation function to change a target attribute data value corresponding to a source attribute stored in a hierarchical data model and an instruction corresponding to the source attribute are provided. The attribute value derivation function is defined by an attribute value derivation header containing metadata describing hierarchical data model and an attribute value derivation instruction for deriving the target attribute based on the source attribute. Using the attribute value derivation function, a target attribute data value is derived. A user interface is generated to display the derived target attribute data value.

Attribute value derivation

A system and method to graphically represent historical product structures. When a computer extracts all change states for a data set corresponding to a first product structure having a plurality of items. The change states associated with each item are concatenated. The concatenated change states relative to each item and to the parametric constraint effective for the data set are displayed on an electronic display. In this way it is possible to visualize the historical product structure.
