This doesn't quite address your issue, but, unless you've hit the 2 GB
Access size limit , Access can handle a good deal more than 250,000
item records ("rows," yes?) you cited.
What makes you think you've hit the limit? Slowness, something else?
All the best,

> Hi all. What are you using to process circ data for ad-hoc queries. I usually extract csv or tab-delimited files - one row per item record, with identifying bib record data, then total checkouts over the given time period(s). I have been importing these into Access then grouping them by bib record. I think that I've reached the limits of scalability for Access for this project now, with 250,000 item records. Does anyone do this in R? My other go-to- software for data processing is RapidMiner free version. Or do you just use MySQL or other SQL database? I was looking into doing it in R with RSQLite (just read about this and sqldf http://www.r-bloggers.com/make-r-speak-sql-with-sqldf/ ) because I'm sure my IT department will be skeptical of letting me have MySQL on my desktop. (I've moved into a much more users-don't-do-real-computing kind of environment). I'm rusty enough in R that if anyone will give me some start-off data import code, that would be great.
