The features of Representational State Transfer

8.05.2014 Julian Blazek
Representational State Transfer (REST) is a basic stateless architecture that mostly runs over HTTP. It involves reading a special web page containing an XML file that describes the required content.

REST has found application in social networking sites, mobile apps, automated business processes and mashup tools. The unique style focuses on interactions between client and services through restricted operations. The style provides flexibility by assigning unique universal resource indicators (URIs) to resources.

There are many architectural properties triggered by the limitations of the REST architectural style. This includes scalability of interactions between component, performance, interface of simplicity, flexibility of components for meeting evolving needs, visibility of interaction between components through service agents, and reliability.

REST is expected to induce the image of the performance of a web application. The style presents the applications with web pages. Users scan progress through an application by choosing links, leading to the next page, getting transferred to the user and rendering for use.

Originally, Representational State Transfer used to be described solely in the context of HTTP. However, with time it expanded beyond the protocol. The REST based architectures could also be created on the basis of other Application Layer protocols if they have an expanded and consistent vocabulary for applications depending on the transfer of important representational state.

REST based applications make the most out of the usage of current and well defined interface and similar built-in features provided by the selected network protocol. They will also help reduce the accumulation of fresh application based features.

Basically, REST is an architectural style that exploits an existing web technology and set of protocols, including XML and HTTP. It is easier to use compared to the more popular Simple Object Access Protocol (SOAP) approach that is based on using/writing a server programme and client programme.
