The Oracle XML DB repository extends the basic XML related functionality of Oracle XML DB, by providing a folder hierarchy that can be used to organize XML content stored inside the database. The hierarchy is optimized for managing XML content but is fully capable of acting as a repository for other, related kinds of content such as Office productivity documents, images and other forms of multimedia content. The Oracle XML DB Repository is fully accessible from SQL and PL/SQL. New views and operators allow SQL queries and updates to be executed on content and metadata managed by folder hierarchy. These operations can be restricted to a particular sub-tree within the repository. A comprehensive set of PL/SQL packages allow developers to perform functions like creating and deleting content, locking and unlocking content, versioning content, moving and linking content. The Oracle XML DB repository allows a path or URL to be used to access content. A new index, the hierarchical index, ensures that the performance of using a path to
