I don't think that we know *exactly* what will happen. Initially, I believe that the plan is to make SAP DB understand the MySQL client-server protocol. This will allow for cooperation with little or no disruption to how SAP DB works now. As time passes, tighter integration will occur. Making the right choices will require that we receive guidance from the community. I suggest that we create a public mailing list specifically for users who wish to participate the SAPDB/MySQL integration work. Since I cannot answer the above questions definitively, I will add them to the SAP DB/MySQL FAQ that will go up on mysql.com in a few days. > >>> - Free from bugs ... > The point is, that even Knuth can't write bug-free software, because he > is "only human". (unfortunately these bugs haven't been found yet) I agree.[0] As I said, it is a *goal*. It is not a statement that we have no bugs - most sane developers will agree that bug-free is state achieved only when software is not running and has no users. ;) ... > MySQL certainly has an image in the DB community. The ones searching for > full-featured (enterprise) DB were always disappointed. I believe that we get negative press from people who do not understand that our greatest strength is ease-of-use and performance, rather than the feature set we support. I agree that we do not have all the features of an enterprise database! At the same time, we excel in the areas that we are deployed in and continue to gain additional funtionality. This is why we are used by leading organizations like Yahoo!, the Wellcome Sanger Trust Institute, Ericsson, the US Census Bureau, etc. In an enterprise setting, we work very well as a compliment to more feature-rich databases and are good at replacing these same databases in areas where they have been over-deployed. > > If your concern is that we are not up to the task technically, we have > > an excellent team - and this team will be working with the SAP DB team. > > Our doubt result from the image MySQL has - so you have to proove that > you can stand that task, and that the result is a DB comparable to > SAPDB.

I do hope that we are given the chance to provide that proof though! Why do you feel that we consider features unimportant? Our focus in the last three years has become much broader. As we have gotten more and more users, they have taught us that they have different needs than we may have. Once we learned this, then we started implementing what they wanted. :) Thanks again for the feedback!
