these data are pulled from Oracle Exadata Storage servers and I don't want to store it in Production databases which are purely meant for storing Customer Data.

Use SQLite or a local PostgreSQL. Both are free as in speech and free as in beer, and both are supported by DBI: DBD::SQLite, DBD::Pg. Note that DBD::SQLite already includes the database engine (SQLite), so after cpan DBD::SQLite, you can start using SQLite without installing anything else.
