XML Schema - XSD

"XSD Training: exciting course that explains how to give information an explicit meaning, enabling machines to automatically process information available on the Web"

XML Schema (XSD) - 2 days

XSD Schema training

XSD training: two-day training during which participants will learn to apply guidelines for practical XML schema creation in the context of BPM systems. The emphasis is on analysis and design of XML vocabularies; therefore, any programming knowledge is not required. The creation of XSD vocabularies and their usage within any modern application is the real focus of this course. Participants will learn how to develop an XML-enabled system, and you will understand the important added value of XSDs for such a system.

Throughout this course, concepts of XML modeling as well as a W3C best practices are used to deliver a comprehensive training experience. Several real-life cases and e-Business examples demonstrate the usage of XML modeling capabilities without losing the primary goal of creating successful applications out of sight. Multiple exercises will deliver a unique hands-on experience that will make the different XML and XSD concepts surprisingly transparent. These example applications using an XML vocabulary, designed in UML, and then transformed to the W3C XML schema language will guide us through these two days.

As always, the course material is based on real-life experience and you will get plenty of practical examples; so if you want to understand exactly how XML and Schemas can work together for your organization, then this course is for you!
