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

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