Analytics is notable in that it is a headline grabbing trend in many domains, but has also been around for a long time under various other labels. One consequence of that longevity is that there is a bewildering array of tools available that can support an analytics process in some way. An exhaustive overview of all such tools is near impossible and probably out of date the moment it's finished. What is possible, however, is to provide a map of the major categories of tools, and highlight some landmark tools that are available now. Because of the diverse history and practice of analytics, many different categorisations are possible, but the authors choose to group them by tradition, or established approach.
