In Gerben's site, Trial Data Solutions, there are several excellent data management tools. One of them uses MS ACCESS. The 32 bit version was very sluggish and it could take more that 30 minutes if you had a database with many patients (>1000) Gerben has developed a new version that works with OC 3.13 and 3.14 and the 64 bit version of PGSQL. It is not yet available on the site but if you ask nicely, I'm sure Gerben will provide it to you. It simply such an major improvement.
