Not quite. You will need numpy *at the core* of PyTables, and this will imply a complete migration from numarray to numpy inside it. If you can achieve this, then you are done, but this is not a trivial task (although feasible indeed). > > Regards > Andrei > > PS: have you seen this site: http://wilmott.com/categories.cfm?catid=10. > People here > need something to deal with huge datasets.

In particular, it is not meant for keeping the integrity of data (it is responsability of user), guaranteing the safety of transactions or maintaining very complex references. So, as I've said many times, it is actually best to use it to *complement* other tools, rather than being an all-in-one solution.
