Enterprise Integration Patterns "Very few business applications can live in isolation. More often than not, applications have to be integrated with other applications inside and outside the enterprise. This integration is usually achieved through the use of some form of "middleware". Middleware provides the "plumbing" such as data transport, data transformation, routing etc."
ROI analyses key factor in web services take-off, report "The results of the poll taken in Germany show that 81 per cent of the companies interviewed judged security as the main restriction on web services taking off, while 74 per cent evaluated a missing (or at least a not properly declared) ROI as a real handicap in regard to web service implementation. Further barriers to success that were named included missing budgets, non-integration of existing applications, and an absence of key skills and know-how within organisations."
