Learning to Use Regular Expressions Often if you find that your regular expressions are matching too much, a useful procedure is to reformulate the problem in your mind. Rather than thinking about "what am I trying to match later in the expression?" ask yourself "what do I need to avoid matching in the next part?" Often this leads to more parsimonious pattern matches. The trick here is that there are two different ways of formulating almost the same sequence. For people who have thought about basic probability, the same pattern occurs. Report: Data Virtualization Market is Strong Report: Data Virtualization Market is Strong The data virtualization space is teeming, peopled by feature-rich platforms from Cisco, Denodo, IBM, and Informatica as well as a few upstarts. By Stephen SwoyerJune 2, 2015 Think you can name the top 10 vendors in the data virtualization (DV) space? If you've been paying close attention, you actually know what data virtualization is. But 10? According to a recent Forrester Wave research report, there are more than two dozen DV players, of which Cisco, Denodo, IBM, and Informatica -- along with Oracle Corp. and SAP AG -- are the undisputed heavyweights. What is data virtualization -- and, most important, why does it matter? Think of DV as a scalable, service-aware, more abstract version of data federation, which is still something of an ugly word in some data warehousing circles. Think, then, of DV as a lot of things -- a jack of all trades, even -- just don't think of it as simply or solely a function of data federation.
