Internal and external objects
Qlik Data Catalyst displays (external) views of source metadata environments in source and (internal) views of data objects loaded into the file system.
Source displays a catalog of metadata that is relevant to lineage, loading, storage and discovery details records and exposes associated metadata that enables users to explore and describe business data. Within Qlik Data Catalyst, one can be looking at an 'external' RDBMS entity via an internal view (discover). An 'internal' source has been created within the environment through ingest, prepare, query, and explore.
