Hi Carsten, it was the decision of the development, that moved to SAP, to drop all activity, which was related to distributed database management. At this point of time we faced severe performance problems caused by the approach to handle distributed update transactions on replicated data. This was caused by the synchronization of locks held on different nodes within a distributed database. On the other hand we had to focus on object management (liveCache). So we choose to decrease comlexity in our db kernel. And looking back this was a good decision (and I don't see any other systems having success with a full distributed approach according to Dates rules).

But I have two comments to make: (1) Rainer Stickdorn's book about Adabas D states, that the database was able to run distributedly on different servers and run transaction covering several servers. SAP DB does not have this ability, so apparently, SAP bought a castrated version of Adabas. (2) Use of SAP DB is more widespread than people think. I know of several companies that already use it, and several consultants who are, well were, in the process of switching their customers web sites from MySQL to SAP DB. The problem is, that nobody hears about them as SAP DB is so easy to use, and even if they want to spend money on it, there is/was no way except for taking one of those excessively priced SAP contracts that no small or medium sized business can afford. If SAP had published the SAP DB manuals as books, or sold cheap support contracts (USD 100 per year for setup, USD 100 per incident or something like this) I'm sure they would have gotten a totally different picture of their own success.
