$database->insert("account", [
	"user_name" => "foo",
	"email" => "[email protected]"
]);

//select
$datas = $database->select("account", [
	"user_name",
	"email"
], [
	"user_id[>]" => 100
]);

//update
$data = $database->update("account", [
	"age[+]" => 1
], [
	"user_id[>]" => 100
]);

//delete
$database->delete("account", [
	"AND" => [
		"type" => "business",
		"age[<]" => 18
	]
]);
