What is the difference between catalog and content?



In HANA Studio every HANA system has two main sub-nodes, Catalog and Content.

Catalog:

  • The Catalog represents SAP HANA’s data dictionary, i. e. all data structures, tables, and data which can be used. 
  • All the physical tables and views can be found under the Catalog node. 

Content:
  • The Content represents the design-time repository which holds all information of data models created with the Modeler. 
  • Physically these models are stored in database tables which are also visible under Catalog. The Models are organized in Packages. The Contents node just provides a different view on the same physical data. 
  • The created Column Views are always located in schema _SYS_BIC, their metadata in schema _SYS_BI.
