XML Training : XML and Web Services Training

XML and Web Services

XML Training Overview

This course provides a brief introduction to the concepts of Service Oriented Architecture before discussing XML and Web Services. XML forms one of the key underlying technologies for enabling web services. You will learn the essentials of data interoperability using XML and well-formed XML documents. This course discusses XML Schemas in sufficient details that are used to define the valid structure of an XML document.

You will then understand about the key building blocks of web services, namely WSDL and SOAP and how they use XML. The participants then look at the various software development methodologies that can be used to develop web services based applications.

XML Training Audience

J2EE developers, architects, project leaders and other IT staff who will like to get an understanding of XML and their role in Web Services.
