SOAP and REST interfaces
The term Web services describes a standardized way of integrating Web-based applications using the SOAP and REST interfaces. Unlike traditional client/server models, such as a Web server/Web page system, Web services do not provide the user with a GUI. Web services instead share business logic, data and processes through a programmatic interface across a network.
OCR Web Service provides programmatic access to using Optical Character Recognition (OCR) technology. Service is implemented using SOAP and REST interfaces and can be accessed through API by HTTP or HTTPS requests.
The applications interface, not the users. Developers can then add the Web service to a GUI (such as a Web page or an executable program) to offer specific functionality to users. Web services allow different applications from different sources to communicate with each other without time-consuming custom coding, and because all communication via HTTP, Web services are not tied to any one operating system or programming language. For example, Java can talk with Perl, Windows applications can talk with UNIX applications.
