Web Services In Symbian OS

This thesis presents different aspects of Web Services usage in Symbian OS that is an operating system for handheld devices. The practical part of the work was to develop Symbian OS client application for Web Services. It produced four reusable software components. XML enables platform and programming language independent services. Web Services use XML to create standardized message oriented services that are accessed through HTTP. Web Services are moving towards dynamic B2B interaction. Web Services increases the amount of transferred data, which is not desirable in mobile networks where transfer speed is slower than in the traditional networks. However the modern mobile networks are able to transfer the extra payload with reasonable time. XML processing is not a big problem. Web Services can be accessed from the modern mobile devices and they can cut down the development costs.
