Abstract

Software as a Service is gaining increasing pre-eminence as a means of delivery of software for business processes. Indeed, as standards develop in this area, the possibility arises that web based Service Oriented Architectures will develop allowing businesses to source services from multiple providers, and integrate them as required. The positive implications of these developments for supporting business flexibility have been widely discussed. However, there may be other business needs that are less well served. In particular, the need to support long term, sometimes permanent data – here termed data longevity- may not be well addressed. This paper reviews literature to identify seven requirements for data longevity, and to assess how well service oriented architectures fulfil those requirements. It finds gaps, and suggests areas for future research.
