What Representational State Transfer Software Architecture

Representational State Transfer is also abbreviated as REST is a type of software architecture consisting of a set of constraints within which data elements, connectors, components, and a hypermedia system exist. The major benefit of using REST is that will overlook the details concerning every component, and it’s associated protocol syntax which means that it focuses on the roles of each of the components, their constraints, and interpretation. While this explanation and definition may not make sense to many, we have a more elaborate explanation below something which is made possible by the developers of stoplight.io

Making Sense of REST Jargon?

Now it goes without saying that we already know that the vast majority of people didn’t understand the above-mentioned explanation. It was too dense, complex and didn’t explain much about the API. But bear in mind that REST at its very heart is a complex and technical system. So, the only way you’re going to understand it is to break it down into more manageable pieces to digest.

REST at the most basic level is a set of rules which are assigned URLs Web Standards as well as HTTP or HTTPs whichever may be the case. When a program complies with the principles of REST, it has to use the full potential of the internet’s architecture. Since its core REST was designed for the internet.

REST Methods and How to Use Them?

Any software developer worth his salt knows that to connect computers via a network, they have to use the same protocol or language. Over the past few decades, there have been several methods developed. Each one of these addresses this communication is a slightly different way. Technologies like XML-RPC, JMS, and SOAP, are to name a few.

Using technologies like SOAP will require much more data for instance and so computers, and in particular, mobile devices don’t have that extra capacity making it unsuitable. That’s one reason why SOAP has been overwhelmingly voted out by most developers as they have over the years gradually migrated towards REST. JMS is another technology which works perfectly for sending messages from one computer to the next and is used in mainly Java applications. XML-RPC is a protocol that makes procedural calls over IP but suffers from the same problems as SOAP.

REST, on the other hand, sits in contrast with SOAP and other similar architectures since data is put through a well-defined mechanism. The data bypass through all the shortest route avoiding all the bulk. Additionally, it also allows for developers to create a program of their own which can access data through the API in the right way which speeds up the transmission of data and can be implemented on computers with limited capacity.

REST Terms :

REST is like a web browser in some ways. The resources are accessible via a URL that URL is accessed by programs and the data is thus extracted. So, it is essential to understand the two main principles, i.e. resources and representations. Resources are the stuff you want to communicate with which can be anything like a sensor, another computer, etc. Representations are what you want to send to the resources.

Conclusion :

The resource or the resources could be at an address which will have to be accessed by sending it information and then receiving a response. To do this Get and Post HTTP methods are used. Some sources may also store information and thus create more resources. That said REST supports other HTTP methods too like Connect, Options, Delete, Put, Head and Connect, etc. Though POST and GET are the most used.
