-- Table structures
-- If using MySQL, update each table definition to use INNODB or foreign keys will be pointless
-- Example:
-- CREATE TABLE "Ingredient" (
-- "name" TEXT NOT NULL,
-- PRIMARY KEY ("name" ASC)
-- ) type INNODB;

Test various key/value "array" type systems in PHP
<?php
# Normal array
$startMemory = memory_get_usage();
$array = range( 1, 100000 );
echo ( ( memory_get_usage() - $startMemory ) / 100000 ), " bytes per element\n";
unset( $array, $startMemory );
# stdClass as a simple map/dictionary
$startMemory = memory_get_usage();
$array = new stdClass();
