You don't tell us the purpose of this exercise, but you might want to query for all sites that have a discharge greater than some threshold, then sort them by location (say within a drainage basin). You might also want to tie these data to a spatial analytical tool. So, how sure are you that each is independent? And, even so, wouldn't one file be easier to maintain?
yes, that is what concerns me. A single file will be easier to maintain, and comparative analysis, if ever needed, between sites would be easier to perform. However, SQLite does offer this ATTACH option, which, as John Stanton mentioned in his suggestion, could be used to bring together disparate site databases for joint queries. Most of the time I am looking at one site, so there is a speed gain by not plowing through other sites' data. This is what is causing me to pause before I rush forward. -- Puneet Kishor http://punkish.eidesis.org/ Nelson Inst. for Env.
