title: Why is the Web Loosely Coupled? A Multi-Faceted Metric for Service Design creator: Pautasso, Cesare creator: Wilde, Erik description: Loose coupling is often quoted as a desirable property of systems architectures. One of the main goals of building systems using Web technologies is to achieve loose coupling. However, given the lack of a widely accepted definition of this term, it becomes hard to use coupling as a criterion to evaluate alternative Web technology choices, as all options may exhibit, and claim to provide, some kind of “loose” coupling effects. This paper presents a systematic study of the degree of coupling found in service-oriented systems based on a multi-faceted approach. Thanks to the metric introduced in this paper, coupling is no longer a one-dimensional concept with loose coupling found somewhere in between tight coupling and no coupling. The paper shows how the metric can be applied to real-world examples in order to support and improve the design process of service-oriented systems. date: 2009-04 type: Conference or Workshop Item type: PeerReviewed format: application/pdf identifier: http://www2009.eprints.org/92/1/p911.pdf format: text/html identifier: http://www2009.eprints.org/92/2/index.html format: application/pdf identifier: http://www2009.eprints.org/92/3/loosely-coupled-www2009.pdf relation: http://dret.net/netdret/docs/loosely-coupled-www2009/ identifier: Pautasso, Cesare and Wilde, Erik (2009) Why is the Web Loosely Coupled?
