- Obyektlar orasidagi munosabatlar
- Tarkibi PHPda muhim tushunchadir. Ushbu dizayn ko'rinishida ob'ekt boshqa ob'ektni yaratadi. Birlashtirish ob'ekt bir nechta ob'ektlardan iborat bo'lganda yuzaga keladi.
- Composition - bu egalik qilishga bo'lgan munosabat samarali, aggregation esa munosabatlarni "o'z ichiga oladi". Kompozitsiyada qismlar o'z ichiga olgan narsadan tashqarida mavjud bo'lolmaydi, lekin alohida narsalar birlashishda noyob birliklar sifatida mustaqil ravishda mavjud bo'lishi mumkin.
