About this Course

This advanced training provides an end-to-end understanding of Oracle XML Database
(XML DB). Participants learn how to design, store, manage, query, and optimize XML
data within Oracle Database. The course emphasizes practical, real-world application
through hands-on labs that simulate enterprise-level XML systems, web services, and
integration scenarios. Each module builds progressively toward mastery of XML DB’s
architecture, storage models, schema management, querying, transformations, and
performance tuning.
