Lug'at kalitlari va qiymatlari har qanday qiymat turi bo'lishi mumkin. Siz kalit yaratishingiz va uning qiymatini lug'at yoki ro'yxatga aylantirishingiz mumkin.

Quyida o'qituvchilar, talabalar va xodimlar ishlaydigan maktab uchun lug'at mavjud. Ularning har birining ismi va shaxsiy guvohnomasi mavjud. Talaba o'zi yozilgan sinfga ega bo'ladi. Talaba bir nechta kurslarga yozilishi mumkin. O'qituvchilarda u o'quvchilarga o'rgatadigan kurslar mavjud. Maktab xodimlarining nomi va kasbi bor.
