Hi Cindy,

This doesn't quite address your issue, but, unless you've hit the 2 GB 
Access size limit [1], 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,
Kevin

> 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.
