Hello pwagyi, and welcome to the Monastery!

Although this is no doubt doable in OO, why reinvent the wheel? If you want SQL-like queries, use a real relational database that supports real SQL! For example, the module DBD::SQLite:

...includes the entire thing in the distribution. So in order to get a fast transaction capable RDBMS working for your perl project you simply have to install this module, and nothing else.

Hope that helps,
