An IDC survey puts the MDM market at USD 10.4 billion by 2009, with a compound growth rate of 13.8%. To save you some Excel exercise, that puts the existing MDM market at USD 5 billion today. This seems quite high, and clearly involves counting the existing sub-markets of CDI (customer data integration) and PIM (product informaton management) which have been around a lot longer than general purpose MDM tools (e.g. Kalido MDM, Oracle Data Hub, Hyperion Razza and SAP MDM or whatever it is called this week). Certainly the latter tools are what has stirred up a lot of interest in the MDM market, since they promise to address the general problem of how to manage master data, rather than dealing with the speicifc point problems of customer and product. This is important, since BP uses Kalido MDM to manage 350 different types of master data, so if we have to have a different software solution for every data type then IT departments are going to be very disappointed indeed! In fact today there are relatively few deployed instances of general purpose MDM tools, which are quite young (KALIDO MDM went on general release in Q3 2004) so it is of great interest to those vendors as to how quickly the “general purpose MDM” market will pick up from its early beginnings to grow to a serious proportion of this overall market. IDC are the most quantitative and thorough of the industry analysts when it comes to market size data, though as ever caution should be used in projecting the future in a straight-line form. Still, even at the current market size of USD 5 billion, it can be seen that this market, which did not even really have a name a year or so ago, is generating a lot of interest.
