Fig. 2: View definition profiles.
From: SQL on FHIR - Tabular views of FHIR data using FHIRPath
Profiles defined as part of the SQL on FHIR view definition specification. The base profile has minimal requirements for quick, on-demand use. The shareable profile adds rules for identifying resources, versioning, and limits FHIRPath usage to work better across different systems. The tabular profile further restricts column data types to simple values only, making the data compatible with formats like CSV and systems that cannot handle complex data.
