They often include a rich set of metadata associated with documents, and a rich set of behaviors with respect to security, access control, locking, versioning, content addressing, retention control, and so on. Because stores are typically designed and evolve independently of each other, applications that use a specific store are either written and packaged by the developers of the store or else require the user to employ a store-specific API. Designers who create a store-specific API must have a detailed knowledge of the schema of the database tables that are used to implement the store.

A content store is a collection of documents. Files stored in the database along with relational data are automatically backed up, synchronized to the disaster recovery site using Data Guard, and recovered together.
With this interface, access to files in the database is no longer limited to programs specifically written to use BLOB and CLOB programmatic interfaces. Files in the database can now be transparently accessed using any operating system OS program that acts on files. For example, ETL extraction, transformation, and loading tools can transparently store staging files in the database and file-based applications can benefit from database features such as Maximum Availability Architecture MAA without any changes to the applications.
Database File System DBFS creates a standard file system interface on top of files and directories that are stored in database tables. About DBFS. Ans: Feature of having duplicate file systems or the fs1 and fs2 are togetherly known as dual file systems in R Ans: Yes. FS1 is a run file and FS2 is a patch file. The roles keep getting changed with each ADOP patching cycle run becomes patch and patch becomes run.
And we also provided the links to previous video blogs to have a better understanding of Oracle E-Business Suite R We cover Oracle E-Business R I have couple of queries to be clarified on this dual file system environment. Online patching is not possible without dual file system. During ADOP the patch is applied in the patch file system, while users continue to use the system through run file system.
Another thing is along with dual file systems there are separate admin servers and node manager for fs1 and fs2 which gets called internally during patching. SecureFiles LOBs support advanced features of compression, deduplication and encryption to files.
Database File System DBFS leverages the features of the database to store files, and the strengths of the database in efficiently managing relational data, to implement a standard file system interface for files stored in the database. Files in the database can now be transparently accessed using any operating system OS program that acts on files.
