IntroductionThis article discusses two service access protocols, SOAP (“Simple Object Access Protocol”) and REST (“Representational State Transfer”). Web ServicesWeb services are defined to actively fetch, read, or transfer from a defined source to produce a specified outcome – a result.The following rudimentary example shows a basic use of web services before understanding how the data is transferred to and from the web service, using SOAP or REST.If a developer is writing an application that requires some data calculation in one place, the will write the calculation method in the code, in that one place.
However, if the data calculation is needed in other parts of the application, it would be inefficient and impractical to maintain if the developer placed the calculation method in every area it is needed.Having to make one change to that method would require finding every instance to edit (and retest). This scenario would benefit from using a web service to function optimally and improve business agility.By creating one web service with accessible methods to add, subtract, divide and multiply, the application will engage with that web service whenever data calculation is required; it calls the web service to do the calculation and produce the result. So there is only one place for the developer to maintain the data calculation method.The way data is handled in web services is determined by whether SOAP or REST is implemented. SOA and BPMNAn application built on executable processes is based on a Service Oriented Architecture (“SOA”). It is an approach on how to use services that transfers, produces, validates or calculates data.SOA is becoming more and more favourable to improve on development quality and time, and improve application performance and scalability.Business Process Modelling Notation (“BPMN”) is modelling a service or business process, which can be done by non-technical people i.e.
BPM for enterprise application integration (EAI) enables companies to achieve. A Web service can be implemented as its own business process, or it may be.
The business analyst. Using BPMN, business models (for services) are easily interpreted by developers who implement the as an executable process, and processes may or may not require human interaction. Simple Object Access Protocol (SOAP)SOAP is a method of transferring data over the internet.Originally developed by Microsoft due to the advent of the internet, SOAP replaced the old DCOM and CORBA technologies, and it has been around for a lot longer than REST.SOAP is regarded as heavier than REST i.e. References:0on DifferenceBetween.net are general information, and are not intended to substitute for professional advice.
