Converting Web applications to data components: design methodology

Most of the current Web applications are closely tied to the client and large parts of their code concern with producing proper output markup. Converting them into components that produce pure data output, independent from presentation specifics, increases maintainability and eliminates duplicated code for different output media, and thus is the key requirement for modem systems. In this paper we explore steps needed to transfer existing applications to data oriented components, and present implementation and performance issues and their solutions.
