WEB APP
For most systems, these specifications are defined in the system’s Web Service Description Language, or WSDL. A WSDL defines how incoming information, such as queries, need to be structured for the service application to make sense of it, and how outgoing data will be structured so that the requesting application can understand it. These definitions are stored as XML (Extensible Markup Language) specifications. A common structure for WSDL information is the Simple Object Access Protocol (SOAP) that allows communication interfaces to be developed without having to rebuild low-level protocol specifications.
Web Services have become the silent but critical backbone to our modern device-driven world. The common protocols, interfaces and communication standards that have evolved over the last 15 years allow us to develop mobile, tablet and PC-based applications through which you can order lunch, verify stock prices or find the perfect gift in a fast, reliable and securely manner.
