# Здесь задекларировано как сейчас этот класс выглядит
# возможно большая часть этого останется и перейдет в финальный вариант
# Важно: в финале у инстанса не будет метода `exec` который есть сейчас, но будет метод `query` который будет вызываться извне, а в результате будет возвращатся объект с интерфейсом QueryObjectInterface , чтобы потом на основе этих данных конструировать на нужном языке запрос в базу данных
