Hi Carlos,
I'm glad to help, but I'd like to clarify several things, first.
> ...with about 200,000 data about books
> (title, clasif, year, publisher, authors, subjects, etc etc)
So you have a single file with data for multiple tables?
> After each sequential parsing (one book)
What defines one book? One file, several records from one or more files, or one record
from a single file?
> i upload that info to the database
You "upload"? How is this done, exactly? Do you mean that you run mysql from one machine
with the host set for another machine?
> ...but in 5 tables...
So you've split your data into sets that need to get loaded into five destination tables,
or you upload five sets of data?
> (verifying duplication, ids, etc):
Does this mean that you are checking for duplicates before loading into MySQL?
