This page introduces the concept of the Data Meaning Layer, a shared framework for defining, tracking, and communicating the meaning of data elements and metrics in CCMDB. It serves as a central reference point for how we manage evolving definitions, support consistent interpretation, and connect meaning across tools like Access/SQL, SAS, Power BI, and the wiki. | This page introduces the concept of the Data Meaning Layer, a shared framework for defining, tracking, and communicating the meaning of data elements and metrics in CCMDB. It serves as a central reference point for how we manage evolving definitions, support consistent interpretation, and connect meaning across tools like Access/SQL, SAS, Power BI, and the wiki. We have a page [[Data Semantics]] that touches on this, and a [[:Category:Data Semantics]] that contain pages about some of the complexity that make such a layer relevant. | ||
