man DBIx::Class () - Extensible and flexible object <-> relational mapper.
NAME
DBIx::Class - Extensible and flexible object <-> relational mapper.
SYNOPSIS
DESCRIPTION
This is an SQL to OO mapper, inspired by the Class::DBI framework, and meant to support compability with it, while restructuring the internals and making it possible to support some new features like self-joins, distinct, group bys and more.
This project is still at an early stage, so the maintainers don't make any absolute promise that full backwards-compatibility will be supported; however, if we can without compromising the improvements we're trying to make, we will, and any non-compatible changes will merit a full justification on the mailing list and a CPAN developer release for people to test against.

QUICKSTART
If you're using Class::DBI, and want an easy and fast way of migrating to DBIx::Class, take a look at DBIx::Class::CDBICompat.
There are two ways of using DBIx::Class, the simple way and the schema way. The simple way of using DBIx::Class needs less classes than the schema way but doesn't give you the ability to easily use different database connections.
Some examples where different database connections are useful are:
different users with different rights different databases with the same schema.
Simple
First you need to create a base class which all other classes will inherit from. See DBIx::Class::DB for information on how to do this.
Then you need to create a class for every table you want to use with DBIx::Class. See DBIx::Class::Table for information on how to do this.
Schema
With this approach, the table classes inherit directly from DBIx::Class::Core, although it might be a good idea to create a parent class for all table classes that inherits from DBIx::Class::Core and adds additional methods needed by all table classes, e.g. reading a config file or loading auto primary key support.
Look at DBIx::Class::Schema for information on how to do this.
