21.1 Overview of DBFS Store Creation and Use

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.
