• سبک بودن: مهمترین مورد سبک بودن آن است؛ چه از لحاظ اجرای برنامه و چه از لحاظ حجم نهایی برنامه
• سریع بودن: مطمئنا ORM‌های طراحی شده‌ی موجود، از سرعت خیلی بدی برخوردار نخواهند بود؛ اگر سر زبان هم افتاده باشند. ولی باز هم انتخاب سریع بودن یک ORM، مورد علاقه‌ی بسیاری از ماهاست.
• یادگیری آسان و کانفیگ راحت تر.
