A stroll through Class::DBI
by Jay Strauss
In summary, Class::DBI maps an instance of an object to a
row in a relational database table. When you operate upon
the object, you affect the underlying database.
Class::DBI takes care of generating all the select,
inserts, updates, deletes... for you. It makes working with
a relational databases almost trivial.
If your anything like me, you started interacting with
your Relational Database Management System (RDBMS), such
as: Oracle, Postgres, MySQL, Sybase, SQLServer... (in my
order of preference :) using Perl via the vendor supplied
command line tool. Shelling out in your script, launching
the command line tool to execute some SQL, catching the
output, parsing it, and using it in your Perl in some
Then I found out about DBI, and the world was beautiful.
I could now connect and execute SQL within perl in an con-
sise and intuitive way. But then I got lazy (a good
thing). And I started writing all kinds of helper modules,
to do all the things I was doing over and over.
Then, I though, "dummy I bet someone has already done
this", so I searched around the web and CPAN, and found
Class::DBI. Since then I've been doing my database inter-
action exclusively via Class::DBI.
