in thread SQL vs Perl table comparing
You need to start learning one or more of those things you mentioned, try some things, and come back with a specific question (perl questions if you decided to go with perl). Also, it's not good form to cross-post without mentioning that you have cross-posted the question between forums.
E.g., start learning perl, write something simple, come back with specific questions, learn how to use the DBI library to access data in databases, write something simple, and come back with more specific questions.
