Hi everyone, I was wondering if opening multiple connections to different databases with MySQL and DBI will hinder the performance/efficiency. Would it be better to connect to one main database containing all your necessary tables (for your forums, comments, member info, blog posts etc.) vs. having to connect to 2-3 different databases that each had the info. For example, I have a Perl Script that verifies the member log-in info, allows them to post comments, and to view blog posts. As of this moment, each of the three functions (verify member, posting comments, and viewing the blog) require me to connect to three different databases. One database for member info, another for posting comments, and the third for blog data.

This will definitely be easier for me if I was just to combine all the tables from each individual database into one database name, that way my script doesn't have to keep making three connect statements to three db's. However, a there may be a downside (if it is considered one), which is having 60 tables inside one single database.

Thanks,
A passing visitor
