G M Tere, B T Jadhav, R. R. Mudholkar . Web Services using Asynchronous Communication. National Conference on Advancement of Technologies – Information Systems and Computer Networks. ISCON, 2 (May 2012), 7-11.
Asynchronous interactions are becoming more important in the implementation of complex B2B Web applications. This paper addresses correlation and coordination issues involved with asynchronous Web services, by studying different mechanisms and metadata structures for supporting them; in addition, several interaction patterns for building asynchronous computations are discussed, and the trade-offs between the various patterns are shown. In conclusion, we illustrate the use of asynchronous Web services in the context of some concrete B2B applications. This paper discusses how to build a web services architecture that handles requests and responses as separate transactions. Not all web services work synchronously; in some situations, responses to web service requests are not provided immediately, but rather sometime after the initial request transactions complete. Such asynchronous operations aren't explicitly supported by web services specifications and standards. In some situations, responses to web service requests are not provided immediately, but rather sometime after the initial request transactions complete. Such asynchronous operations aren't explicitly supported by web services specifications and standards; however, those standards do include the infrastructure and mechanisms on which asynchronous operations can be based. In this paper, several design patterns for asynchronous web services are discussed.
