You may use Apache::Session::MySQL.

Despite the name, and despite being designed for using with mod_perl, you can use it even in a non-web application. Or, as the docs say

it can also be used for any situation where data persistence is desirable.

It's a ready to use framework. Look at the docs. It's quite easy to store a data structure into a database table, and even to use it with a tied hash.
