    XQuery Intro

    Attention is paid to the syntax of XQuery, the XQuery specification and the parts of XQuery.

    XML Vocabularies

    Also the relationships of XQuery with other XML vocabularies such as XPath, XSLT and XML Schema are discussed.

    XQuery Data Types and Expressions

    Furthermore the data types, built-in functions of XQuery and the different XQuery expressions are discussed.

    Flower Expression

    The so called flower expressions which are characteristic for XQuery are treated in detail.


    Finally attention is paid to some more advanced applications of XQuery like joins, the use of XQuery in combination with other technologies and for the accessing of relational data.

    Audience Course XQuery

    The course XQuery is designed for developers who wish to apply XQuery in practice for the selection of XML data.

    Prerequisites Course XQuery

    To participate in this course basic knowledge of XML and HTML syntax is required. Experience with programming and Structured Query Language (SQL) is beneficial for a good understanding.

    Realization Training XQuery

    The theory is discussed on the basis of presentation slides. Demos are used to clarify the theory. The theory is interspersed with hands-on exercises. Usage is made of modern XQuery tools and the course material is in English. The course times are from 9.30 up and to 16.30.

    Certification XQuery

    After successful completion of the course, participants receive an official XQuery certificate.
