=head1 NAME
DBIx::Class - Extensible and flexible object <-> relational mapper.
=head1 SYNOPSIS
=head1 DESCRIPTION
This is an SQL to OO mapper, inspired by the L<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.

=head1 QUICKSTART
If you're using L<Class::DBI>, and want an easy and fast way of migrating to
DBIx::Class, take a look at L<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.
=head2 Simple
First you need to create a base class which all other classes will inherit from.
See L<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 L<DBIx::Class::Table> for information on how to do this.
=head2 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 L<DBIx::Class::Schema> for information on how to do this.
