440 | =head1 DESCRIPTION | ||||
441 | |||||
442 | This class requires L<SQL::Translator> installed to work. | ||||
443 | |||||
444 | C<SQL::Translator::Parser::DBIx::Class> reads a DBIx::Class schema, | ||||
445 | interrogates the columns, and stuffs it all in an $sqlt_schema object. | ||||
446 | |||||
447 | Its primary use is in deploying database layouts described as a set | ||||
448 | of L<DBIx::Class> classes, to a database. To do this, see | ||||
449 | L<DBIx::Class::Schema/deploy>. | ||||
450 | |||||
451 | This can also be achieved by having DBIx::Class export the schema as a | ||||
452 | set of SQL files ready for import into your database, or passed to | ||||
453 | other machines that need to have your application installed but don't | ||||
454 | have SQL::Translator installed. To do this see | ||||
455 | L<DBIx::Class::Schema/create_ddl_dir>. | ||||
456 | |||||
