🌐 Lesson 51: Django Tutorial (Web Development Basics)
1. Django ဆိုတာဘာလဲ?
မြန်မာ → Django ဆိုတာ Python အတွက် high-level web framework တစ်ခု ဖြစ်ပြီး, rapid development (အမြန်တည်ဆောက်နိုင်ခြင်း) နဲ့ clean design (သန့်ရှင်းတဲ့ structure) အတွက် အထူးကောင်းတယ်။
English → Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design.
2. Why Use Django?
- Built-in features (authentication, admin panel, ORM) ပါပြီးသား
- Security အရမ်းကောင်း (SQL injection, XSS, CSRF ကာကွယ်ပေးတယ်)
- Scalable → small project ကနေ enterprise-level app အထိ တည်ဆောက်နိုင်တယ်
3. အကျဉ်းချုပ်
✅ Django = Python web framework
✅ Built-in features → admin, ORM, authentication
✅ Project structure → settings, urls, apps
✅ ORM → database ကို Python class နဲ့ ကိုင်တွယ်နိုင်တယ်
