Semantic Usage

In this scenario, one may wish to see the usage of the semantic element (e.g., glossary term) in the architecture.

In this scenario, from a glossary term or conceptual/logical model element one may wish to simply discover what data element are semantically mapped in the data flow architecture and thus would be impacted by a change to the term or model element.

A semantic usage lineage trace is nearly the reverse of semantic definition lookup. In general it is requested from a term’s or logical model element’s object page. The usage trace itself proceeds down each semantic link and then traces the data flow where there are no transformations (pass-through lineage) to all objects which may be reached in this manner.

Example

Navigate to the term Account Amount Available in the Finance Glossary. Then click the Semantic Flow tab and List tab on the left.

You see a list of all the objects that express the term Account Amount Available, whether by semantic mapping including term mapping link (Mapped Semantically), by inferred equivalence due to pass-through lineage in the data flow (Inferred from Lineage), by inferred equivalence due to data classification (Inferred from Classification), or the result of a name matching search (Searched).
