Course Outline
XQuery is a generic technology and will be taught in a generic, language context. XQuery implementations are associated with database products, where the tool-specific skills are greater than just the XQuery components.
To avoid this the tool used will be an XQuery engine, one of the most popular, open-source XQuery implementations that operates directly on XML documents in filestore.
Course Content
Our comprehensive XQuery training course provides an intensive hands-on introduction to using XQuery in a commercial environment.
Available as a public or closed course at our London training centre, or can be tailored to your team's requirements and delivered onsite as a bespoke, customised training course.
