NAME

       MySQL::Diff::Database - Database Definition Class

SYNOPSIS

	 use MySQL::Diff::Database;

	 my $db = MySQL::Diff::Database->new(%options);
	 my $source    = $db->source_type();
	 my $summary   = $db->summary();
	 my $name      = $db->name();
	 my @tables    = $db->tables();
	 my $table_def = $db->table_by_name($table);

	 my @dbs = MySQL::Diff::Database::available_dbs();

DESCRIPTION

       Parses a database definition into component parts.

METHODS

   Constructor
       new( %options )
	   Instantiate the objects, providing the command line options for database access and process requirements.

   Public Methods
       o   source_type()

	   Returns 'file' if the data source is a text file, and 'db' if connected directly to a database.

       o   summary()

	   Provides a summary of the database.

       o   name()

	   Returns the name of the database.

       o   tables()

	   Returns a list of tables for the current database.

       o   table_by_name( $name )

	   Returns the table definition (see MySQL::Diff::Table) for the given table.

FUNCTIONS

   Public Functions
       o   available_dbs()

	   Returns a list of the available databases.

	   Note that is used as a function call, not a method call.

NAME

       Algorithm::Diff::XS - Algorithm::Diff with XS core loop

SYNOPSIS

	   # Drop-in replacement to Algorithm::Diff, but "compact_diff"
	   # and C<LCSidx> will run much faster for large data sets.
	   use Algorithm::Diff::XS qw( compact_diff LCSidx );

DESCRIPTION

       This module is a simple re-packaging of Joe Schaefer's excellent but not very well-known Algorithm::LCS with a drop-in interface that
       simply re-uses the installed version of the Algorithm::Diff module.

       Note that only the "LCSidx" function is optimized in XS at the moment, which means only "compact_diff" will get significantly faster for
       large data sets, while "diff" and "sdiff" will run in identical speed as "Algorithm::Diff".

BENCHMARK

			     Rate     Algorithm::Diff Algorithm::Diff::XS
       Algorithm::Diff	   14.7/s		   --		     -98%
       Algorithm::Diff::XS  806/s		5402%		       --

       The benchmarking script is as below:

	   my @data = ([qw/a b d/ x 50], [qw/b a d c/ x 50]);
	   cmpthese( 500, {
	       'Algorithm::Diff' => sub {
		   Algorithm::Diff::compact_diff(@data)
	       },
	       'Algorithm::Diff::XS' => sub {
		   Algorithm::Diff::XS::compact_diff(@data)
	       },
	   });
