Commercial database systems have built up the very powerful notion of a table for use as a container for structured data. The strong management capabilities that such systems provide have fueled the desire to unify the storage and retrieval of other kinds of data under the same umbrella. However, when it comes to unstructured or semistructured documents, a folder hierarchy is a more natural container than tables. Oracle implements a feature- rich XML Repository within the database, which creates a way to view database content as versionable folders in a hierarchy secured by standard WebDAV ACLs and accessed from a variety of file- oriented protocols like FTP, HTTP, NFS and WebDAV. In addition, the Repository is accessible from SQL, and documents stored in this repository can be queried for organization, metadata (including user-supplied metadata), as well as content. In this paper we discuss the main features and architecture of the Oracle XML DB Repository.
