Simple30 second: naam, degree, project kya hai, stack (Flask + Jinja + SQLAlchemy + SQLite).

Example

Main Priya, IITM BS. MAD1 mein parking/ticket app — Flask backend, Jinja templates, session login, SQLite.

SimpleDemo script pehle se practice: 5–7 min, Admin + User roles, saare mandatory features.

Suggested flow1) Register/login user
2) Admin login — CRUD
3) Approval/blacklist
4) Booking/apply + edge case
5) Search
6) Logout

Viva tipBolte-bolte dikhao. Code tab kholna jab poochhein.

SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.

Example

/* button red */
.btn-primary { background: red; }

/* center navbar item */
.navbar { justify-content: center; }

Viva tipDevTools se pehle try, phir file mein permanent change.

SimpleVue = UI ka smart assistant. Data badlo, screen khud update. MAD1 Jinja har click pe naya HTML.

Progressive frontend framework. Components, reactivity, directives.

MAD2 SPA: ek index.html, Vue Router pages, Flask sirf JSON.

Fayde: easy, SFC, docs. Vs React: templates HTML-like, course sikhata hai. Vs plain JS: baar-baar DOM mat chhedo.

Example

<!-- HelloWorld.vue -->
<template>
  <h1>{{ msg }}</h1>
</template>
<script>
export default { data() { return { msg: 'Hello' } } }
</script>

Project example: Navbar.vue + views (Login, Dashboard). data() / setup() reactive. fetch APIs.

Viva tipFayde: easy, SFC, reactivity. Vs React: chhota learning curve. Vs plain JS: UI state auto-update.

SimpleORM = Object Relational Mapping. Database tables ko Python classes/objects se map karta hai, raw SQL kam likhni padti hai.

Bina ORM: cursor.execute('SELECT * FROM user WHERE id=?', [5])
ORM se: User.query.get(5) ya db.session.get(User, 5)

Example model

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

FaydePython mein soch sakte ho, SQL injection se protection (parameterized), relationships easy, DB switch thoda aasan.

Nuksaancomplex queries slow/abstract, seekhne ki layer extra, kabhi raw SQL phir bhi chahiye.

MAD1: SQLAlchemy (Flask-SQLAlchemy). Tables db.create_all() ya migrations se banti hain.

SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.

Example

/* button red */
.btn-primary { background: red; }

/* center navbar item */
.navbar { justify-content: center; }

Example

    email = db.Column(db.String(120), unique=True)

User.query.get(5)  # SELECT ... WHERE id=5

SimpleRedis fridge pe sticky note hai — poori kitchen (database) kholne ki zarurat nahi.

Redis in-memory key-value store hai. Data RAM mein rehta hai, isliye disk wale SQLite/Postgres se kai guna tez.

MAD2 mein Redis do kaam karta hai:
1) Cache — same venue/show/dashboard JSON baar-baar DB se mat nikaalo.
2) Celery message broker — Flask task queue mein daalta hai, worker uthata hai.

Source of truth database hi hai. Redis band ho to cache miss ho jaata hai aur Celery queue ruk sakti hai. Crash pe cache gayab ho sakta hai — isliye important data sirf Redis mein mat rakho.

Example

import redis
r = redis.Redis(host='localhost', port=6379, db=0)
r.set('venues', json.dumps(data), ex=30)
print(r.get('venues'))

Project example: GET /api/venues pehle Redis dekho. Miss pe SQLAlchemy query, phir SET with timeout. Celery worker Redis list se daily reminder uthata hai.

Viva tipCache ke liye db=1, broker ke liye db=0 rakhna smart hai taaki keys mix na hon. Viva mein redis-cli ping → PONG dikhana strong hai.

Status codes sahi. Password JSON mein nahi.

Examiner 2 cheezein: simple desi line + tumhare project ki exact file.

Line pe ungli: input kahan, kaunsa check, query/cache/task, JSON/UI. Copilot band. Jo nahi kiya honestly bolo + kaise add karte.

Example

    d = request.get_json()
    return jsonify(result=d['a'] + d['b'])

Project example: resources.py new Resource. Test Thunder. Optional Vue fetch.

SimpleDirectives Vue ke special attributes — HTML ko superpower.

v-if/else/show, v-for, v-bind (:), v-on (@), v-model, v-html (XSS), v-cloak, v-slot.

:src = v-bind:src. @click = v-on:click.

Custom directives bhi (v-focus) — course basics kaafi.

Example

<p v-if="ok">Yes</p>
<li v-for="u in users" :key="u.id">{{ u.name }}</li>
<input v-model="email">
<img :src="url">

Project example: List v-for :key. Form v-model. Admin v-if. Image :src.

Viva tip: src ke liye v-bind:src ka shorthand. @click = v-on:click.

SimpleProps parent ki thali child ko dena. Child thali tod ke parent ki thali na badle — emit bolo.

Declare props, parent :venue="v". One-way. Mutate mat. Types/required Vue 3.

List parent, card child — classic viva.

Component = reusable UI block (Navbar, Card). Props parent→child data, emit child→parent event. Slots parent HTML inner content.

computed cache + reactive derive (filtered list). watch side-effect (query change pe API). methods events. ref() primitive, reactive() object. Vuex/Pinia global store; localStorage persist, store nahi.

SFC: template + script + style ek .vue file. Parent-child exam favourite: list parent, row child :item + @delete.

Example

<VenueCard :venue="v" @select="onSelect" />
props: ['venue']
this.$emit('select', this.venue.id)

Project example: VenueCard :venue. Child $emit('select', id).

SimpleORM = translator. Python object bolo, woh SQL mein baat kare.

Object Relational Mapper. Class User ↔ table user. Raw SQL kam.

SQLAlchemy MAD1/MAD2. Fayde: portable SQLite→Postgres, relationships, parameterized queries (injection kam).
Nuksaan: N+1, hidden SQL, complex reports pe raw better.

Direct sqlite3 se SQLAlchemy isliye: models, switch DB, safer queries.

Example

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(128), unique=True)
User.query.filter_by(email='a@b.com').first()

Project example: models.py db.Model. resources User.query.filter_by. Koi f-string SQL nahi.

Viva tipFayde: safe-ish, portable (SQLite→Postgres). Nuksaan: complex queries, N+1, leaky abstractions. Direct SQLite se SQLAlchemy isliye: models + injection protection + switch DB.

SimpleRedis fridge pe sticky note hai — poori kitchen (database) kholne ki zarurat nahi.

print(r.get('venues'))

Project example: GET /api/venues pehle Redis dekho. Miss pe SQLAlchemy query, phir SET with timeout. Celery worker Redis list se daily reminder uthata hai.

Viva tipCache ke liye db=1, broker ke liye db=0 rakhna smart hai taaki keys mix na hon. Viva mein redis-cli ping → PONG dikhana strong hai.

SimpleMAD2 course Redis isliye: ek tool mein cache + Celery broker.

Memcached sirf cache. RabbitMQ sirf queue. Redis dono + easy install.

Student project size pe SQLite + Redis kaafi. Production mein hosted Redis, persistence optional.

Redis in-memory key-value store hai — fridge pe sticky note, poori kitchen (SQL database) har baar mat kholo.

MAD2 mein Redis do kaam: (1) cache — same venues/shows/dashboard JSON baar-baar DB se nahi (2) Celery broker — Flask task queue mein daalta hai, worker uthata hai.

Flow: cache.get(key) → hit pe return, miss pe SQLAlchemy + SET with timeout. Admin write ke baad cache.delete, warna stale list.

Source of truth database hi hai. Redis crash/band = cache miss (app chalni chahiye) + queue ruk sakti hai. Important bookings sirf Redis mein mat rakho.

Alag: Redis ≠ Memcached (Celery broker nahi). Redis ≠ localStorage (woh browser). redis-cli ping → PONG viva proof.

Project example: requirements.txt: redis, Flask-Caching, celery. README: redis-server pehle chalao.
