=head1 NAME
Tangram::Driver::mysql - Orthogonal Object Persistence in Mysql databases
=head1 SYNOPSIS
use Tangram;
use Tangram::Driver::mysql;
$schema = Tangram::Driver::mysql->schema( $hashref );
Tangram::Driver::mysql->deploy($schema, $dbh);
$storage = Tangram::Driver::mysql->connect( $schema,
$data_source, $username, $password );
$storage->disconnect();
Tangram::Driver::mysql->retreat($schema, $dbh);
=head1 DESCRIPTION
This is the entry point in the mysql-specific object-relational
persistence backend.
This backend makes use of Mysql extensions SELECT GET_LOCK, SELECT
RELEASE_LOCK and LAST_INSERT_ID to safely allocate object ids in the
absence of transactions.
The vanilla Relational backend may not be used with Mysql databases in
multiprogramming context.
=head1 METHODS
This backend does not add any methods; for a description of
available methods, see L<Tangram::Relational>.
