What is a Web Service Anyways?  Web API  Communicate using open protocols  Self-contained and self-describing  Can be discovered using UDDI  Can be used by other applications  Based on XML IIS

Creating a Web Service  XML (Extensible Markup Language)  Mark-up language designed to carry, not display data  WSDL (Web Services Description Language)  XML based format for describing Web Services  Web Service Interface  SOAP (Simple Object Access Protocol)  Defines the XML format for the messages  UDDI (Universal Description Discovery and Integration)  Specification for creating an XML based registry that lists information about existing Web Services

Using Web Services Advantages  Application and data integration  Versatility  Code re-use  Cost savings Disadvantages  Standards don’t exist for everything  Potential slow performance  Possible to evade existing security measures
