Derivation Set Tracing for the Transformation Diagram Based on Wivern
Qingbao Liu · Computer Engineering and Science · 2004
This paper introduces the main problems of data lineage tracing for the transformation diagram based on Wivern. First, we construct weak derivation sets according to the continuable tracibility,disscus the verification issue of weak derivation sets,and give the relevant verification methods by the types and properties of different transformations and attribute mappings.
