Why XML in the Database  Enforce and leverage the XML data model – Loosely coupled, flexible applications – XML Schema, DOM  Enable richer semantics and better management for content-oriented applications – Store as XML vs. Files or LOBs – Queryability, Integrity, RAS etc.  Process XML close to data for high scalability and performance – Generation, Transformation – Superior memory management for large XML

Why XML in the Database  Reduce maintenance costs of extra moving parts – Eliminate separate ‘XML-processing’ layers  Keep applications standards-based – W3C, IETF, ANSI/ISO, J2EE – Eliminate proprietary file formats, message formats, delimited columns

Oracle9iR2: XML DB Enhanced XMLType XML Repository

Enhanced XMLType  XMLSchema Support  Object-Relational Storage Maintaining DOM fidelity  XML-specific memory mgmt for better scalability and performance  Built-in XML operators for SQL/XML interchangability  XPath Search in the server, and piecewise update of XML via XPath  XSL Transforms in the server  Enhanced XML Views for creating your own efficient representations of XML

XML Repository  FTP, WebDAV, HTTP protocol servers to move XML content in and out  ‘Foldering’ and Repository view over XML Content including access control – Hierarchical Index, SQL Versioning  SQL Repository Search

9 Benefits of XML DB  XML SQL ‘duality’ – SQL operations over XML data, XML operations over SQL data  Native support for XML data model – XML Schema Constraints, other constraints, RI  Storage and Structure Independence  Strong data management over XML content vs. file storage  Repository Functionality  Multiple XML views over relational data  Ease of Presentation and Interchange – Native XSLT, built-in generation  Popular API access – DOM, SQL, PL/SQL, Java, …  XML-specific performance and scalability
