Synchronous vs Asynchronous Web Services – Visualpath

1. Synchronous vs Asynchronous Web Services – Visualpath A web service is any piece of software that makes itself available over the internet and uses a standardized XML messaging system. A Web service is a software service used to communicate between two devices on a network. More specifically, a Web service is a software application with a standardized way of providing interoperability between disparate applications. Synchronous Web Services This type of service execution provides an immediate response to a query. In this situation, the client will wait until the server sends back the response message. The advantage of using the synchronous service is that the client application knows the status of the Web service operation in a very short time. When a Web service client sends a synchronous SOAP request to Oracle E-Business Suite service, the SOAP response will be sent back to the client as soon as the process completes. Asynchronous Web Services (SOAP Web Services Only) This type of service execution may require a significant amount of time to process a request. However, the client that invoked the Oracle E-Business Suite Web service can continue with other processing in the meantime rather than wait for the response. When a Web service client sends a SOAP request to Oracle E-Business Suite service, on completion of service execution, the SOAP response (service response payload) is sent to ReplyTo address of the client. This pattern does not expect acknowledgment from client as it is a fire-and-forget message exchange pattern for callback. SOAP services, depending on specified interaction patterns, can be generated synchronously, asynchronously, or both synchronously and asynchronously to meet your business needs. REST services can be generated with synchronous operation only. Once a SOAP service has been generated and deployed to an Oracle SOA Suite WebLogic managed server, service consumers or Web service clients can send request messages through Oracle SOA Suite. After security checks on the inbound requests, Oracle E-Business Suite Web services can be invoked synchronously or asynchronously. What Are RESTful Web Services? RESTful web services are built to work best on the Web. Representational State Transfer (REST) is an architectural style that specifies constraints, such as the uniform interface, that if applied to a web service induce desirable properties, such as performance, scalability, and modifiability, that enable services to work best on the Web. In the REST architectural style, data and functionality are considered resources and are accessed using Uniform Resource Identifiers (URIs), typically links on the Web. The resources are acted upon by using a set of simple, well-defined operations. The REST architectural

In the REST architecture style, clients and servers exchange representations of resources by using a standardized interface and protocol. For more information Click Here Contact Us: 9989971070
