development

I am seeking advice about what might be the best database program to use to create a large pre-MySQL database, from which I will select the content to export/import/enter into a Drupal MySQL database.

I am developing my first Drupal site -- a web portal where information will be organized by relevance to various generations. The site will launch with a Baby Boomer orientation, with information organized for various baby boomer niches, and then expand to serve more generational niches.
