I'm a J newbie, with grand plans to use J as a reporting tool against a large, sparse, numerically-encoded multi-dimensional OLAP-like "cube". (Anything to keep from using SQLServer!)
I don't currently have a good handle on how big this data may become (clinical trial data). If I can go with the 64-bit version, what kind of size limits would I have to worry about? If I use mapped files, what does that do to size limits? A more specific question: I see postings on the forum as recently as 2008 saying that mapped files cannot support sparse arrays - is that still the case with j602a? Does that change with the j701 beta? TIA for any and all advice and assistance, and for your patience with a newbie! ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
