=head1 NAME

NGCP::Schema - DBIC-derived ORM schema classes

=head1 SYNOPSIS

    use NGCP::Schema::accounting;
    use NGCP::Schema::billing;
    use NGCP::Schema::carrier;
    use NGCP::Schema::kamailio;
    use NGCP::Schema::ngcp;
    use NGCP::Schema::provisioning;
    use NGCP::Schema::sipstats;

=head1 DESCRIPTION

See
L<NGCP::Schema::accounting>,
L<NGCP::Schema::billing>,
L<NGCP::Schema::carrier>,
L<NGCP::Schema::kamailio>,
L<NGCP::Schema::ngcp>,
L<NGCP::Schema::provisioning>,
L<NGCP::Schema::sipstats>.

=head1 INCOMPATIBILITIES

Version 2 moves the result classes of all tables into one namespace. This means the following table names collide:

    accounting.acc_backup       kamailio.acc_backup
    accounting.acc_trash        kamailio.acc_trash
    accounting.acc              kamailio.acc
    accounting.mark             sipstats.mark
    billing.contracts           carrier.contracts
    billing.customers           carrier.customers
    billing.orders              carrier.orders
    billing.payments            carrier.payments
    billing.voip_subscribers    provisioning.voip_subscribers

This is solved by prefixing the result class name I<on the right-hand side only> with the database name and an
underscore, e.g. table C<provisioning.voip_subscribers> becomes the result class <provisioning_voip_subscribers>.
