This diagram shows a database containing joined panels, one labeled DBFS Content API facing out of the database, and the other labeled DBFS Content SPI, with arrows going to objects in the database, including DBFS SecureFile Store which points to another database (outside this database); DBFS hierarchical Store which points to a picture of two tapes and a cloud symbolizing Cloud Storage (both outside the database); and finally the User Defined Store which is defined with broken lines to indicate it is a placeholder for what the user creates.

The Content API points to processes outside the database, including File System Mount Interface, DBFS Command Line Interface Client, DBFS PL/SQL Client, DBFS Links, OCI LOB interface, and PL/SQL LOB interface.
