Thanks for the feedback guys!
The database and code will be on the same machine. Sorry for the broad criteria, I should have just put in the ceiling values. They could get very high which is where I needed the feedback.
My first thoughts were to use the system memory to load data file lines into a hash and load the DB records into an array (or visa versa) and check against each other. My hesitation on that was the memory load if the lists are large and more than one user runs this script
I like the idea in dumping the data files names into a table and querying against that!
I'll look into doing both solutions. If the data file and database isn't that large, I'll load it into memory with hashes, or I'll dump it into a table and query against it.
tilly, your approaches will take me a few days to process, maybe i could write a script to help me process your solutions quicker.. =o) great food for thought
Thanks again for the feedback!
