In order to customize a DBFS store, you must implement the DBFS Content SPI
DBMS_DBFS_CONTENT_SPI). It is the basis for existing stores such as
the DBFS SecureFiles Store and the DBFS Hierarchical Store, as well as any user-defined DBFS
stores that you create.
Client-side applications, such the PL/SQL interface, invoke functions and procedures in the DBFS Content API. The DBFS Content API then invokes corresponding subprograms in the DBFS Content SPI to create stores and perform other related functions.
Once you create your DBFS store, you use it much the same way that you would a SecureFiles Store.
