declaration, like so...
- package MyDatabase::Main::Artist;

use base qw/DBIx::Class::Core/;

my $schema
- = MyDatabase::Schema->connect(

With these scripts we're relying on @INC looking in the current
-working directory. You may want to add the MyDatabase namespaces to
+working directory. You may want to add the MyApp namespaces to
@INC in a different way when it comes to deployment.
The F<testdb.pl> script is an excellent start for testing your database
model.
This example uses L<DBIx::Class::Schema/load_namespaces> to load in the
-appropriate L<Row|DBIx::Class::Row> classes from the MyDatabase::Main::Result namespace,
-and any required resultset classes from the MyDatabase::Main::ResultSet
+appropriate L<Row|DBIx::Class::Row> classes from the MyApp::Schema::Result namespace,
+and any required resultset classes from the MyApp::Schema::ResultSet
namespace (although we created the directory in the directions above we
did not add, or need to add, any resultset classes).
If you are using L<Catalyst>, then you can use the helper that comes with
L<Catalyst::Model::DBIC::Schema>:
- $ script/myapp_create.pl model MyDB DBIC::Schema MyDB::Schema \
+ $ script/myapp_create.pl model MyModel DBIC::Schema MyApp::Schema \
create=static moniker_map='{ foo => "FOO" }' dbi:SQLite:./myapp.db \
on_connect_do='PRAGMA foreign_keys=ON' quote_char='"'
You can also use a GUI database browser such as
L<SQLite Manager|https://addons.mozilla.org/firefox/addon/sqlite-manager>.

+Have a look at the schema classes files in the subdirectory F<MyApp>. The
+C<MyApp::Schema> class is the entry point for loading the other classes and
interacting with the database through DBIC and the C<Result> classes correspond
to the tables in the database. L<DBIx::Class::Manual::Example> shows how to
write all that Perl code. That is almost never necessary, though. Instead use
A L<schema|DBIx::Class::Manual::Glossary/Schema> object represents the database.

- my $schema = MyDatabase::Main->connect('dbi:SQLite:db/example.db');

The first four arguments are the same as for L<DBI/connect>.
