About this Unit
In 2015, this unit is replaced by 301041 Service Oriented Architecture. Web Services is a fast growing area of web-based application development. It goes further than, and is built upon, web site and enterprise-wide applications, which have been the main focus of web development so far. Web services go beyond the boundaries of a single organisation and make it possible to seamlessly bind several applications from one or more organisations to give a consolidated or unified service to users. The challenges to application development thus come from multiple sources and are more complex than until now. There are new technologies, protocols and standards to master and issues like security, trust and performance to address that again transcend the normal organisational limits. In a layered approach to understand web development, if layer one is web site, then layer two is web-based application within an enterprise and web services form layer three, straddling one or more applications, not all of them necessarily web-based and one or more organisations. This unit will cover the technologies, standards and protocols essential for web services and the issues that must be addressed for their success.
