This database was programmed back in 1999, when there was no widespread adoption of MySQL, PostgreSQL or any other free database by ISPs, particularly in Mexico. It is not intended to replace a larger relational database, but to provide really simple database services to small applications, for customers that are on a budget but require web-based systems to share their data. It might also serve as an example Perl module with complex file input and output operations.
Perl Database is, as its name implies a Database written in Perl. I wrote this simple database because it can be installed easily on any web server that supports Perl and keeps cost down. If you require a lightweight database to hold a few records with reduced maintenance costs –you will find low price packages from ISPs with support for Perl– this database might be what you need.
It is currently being used at CMO's website
