SimpleLevel = viva difficulty band. Level 1 usually demo + basics; higher pe live coding + deeper theory.

Viva tipJo level assign hai uske hisaab se demo + theory ready rakho.

Simplevenv activate → dependencies → DB create/migrate → flask run. Browser pe localhost dikhao.

Example

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
flask run

SimplePehle 1-line definition, phir apne MAD1 project mein file dikhao, phir chhota example.

Suggested flow1) Concept kya hai?
2) Mere code mein kahan?
3) Example / demo
4) Edge case

Example

# related file: models.py / routes / template
# formula: request → check/auth → DB → render/redirect

Viva tipExact line yaad nahi to honestly related part dikhao. Bluff mat karo.

SimpleCascade parent delete pe children pe kya ho: delete-orphan related rows hata deta hai.

Example

db.relationship('Spot', cascade='all, delete-orphan')

Viva tipParking lot delete → uske spots/bookings policy clear bolo.

SimpleAuthentication: tu kaun hai? (login). Authorization: tujhe permission hai? (role check).

Example

# auth
if check_password_hash(user.password, pwd):
    session['user_id'] = user.id

# authz
if user.role != 'admin':
    abort(403)

Simplerender_template Jinja HTML file ko data deke final HTML banata hai.

Example

return render_template('dashboard.html', user=user, lots=lots)

SimpleBase template pe navbar/footer, child pages {% extends %} + {% block %} se content bharte hain. DRY.

Example

{# base.html #}
{% block content %}{% endblock %}

{# home.html #}
{% extends 'base.html' %}
{% block content %}
  <h1>Home</h1>
{% endblock %}

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.

SimpleSQLAlchemy MAD1 ka common ORM. Flask-SQLAlchemy wrapper se db.Model, db.session.

Example

user = User(email='a@b.com')
db.session.add(user)
db.session.commit()
users = User.query.filter_by(role='admin').all()

SimpleVertical badi machine. Horizontal aur boxes + load balancer. JWT stateless horizontal friendly.

10k users: Postgres, Redis, gunicorn, CDN, pagination, indexes.
Millions: replicas, queue partition, more workers.

Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).

4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.

Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.

Project example: Course app vertical enough. Design answer scale-out.

SimpleTime complexity input size ke saath time kaise badhta hai.

O(1): dict lookup. O(n): list mein loop. O(n^2): nested loops.

Example

User.query.all() phir Python mein filter = O(n). DB pe indexed WHERE tez.

Search suggestions: prefix index / ILIKE, nai to har keypress pe poori table mat ghumao.

SimpleViva wrap-up hai. Short thanks + confirm submission ZIP latest hai.

SimpleProject overview: problem → roles → main entities → key flows (register, book, admin approve).

Viva tip1 minute elevator pitch ready rakho, phir demo.
