=== Анализа според покривачи

Од анализирање на покривачите може да ги забележиме следните проблеми во нормализацијата на базата:

* Транзитивни зависности во податоците за возила: `veh_id → veh_last_service, veh_last_service_km`
* Недостига зависноста `(ord_id, art_id) → quantity, price`
* Историја на цени и вредност - `unit_id → unit_cost_price`
* Поврзување на слики: `img_id → img_ent_type, img_ent_id`
