Yeh MAD-1 viva question tumhare project ke context se linked hai. Short answer is structure se do:

Pehle 1 line definition/purpose, phir tumhare project ka example, phir chhota code/flow.

Typical Flask flowBrowser request → @app.route controller → SQLAlchemy model/DB → Jinja template response.

Auth: session['user_id'] + role check. CRUD: add/commit, query.all, field update, delete.
Live change maange to: related model → route → template, phir browser refresh karke dikhao.

Example (generic create):
obj = Model(name=request.form.get('name'))

db.session.add(obj); db.session.commit()
return redirect(url_for('list_view'))

SimpleDijkstra shortest path in weighted graph (non-negative). Priority queue + distances. Parking app se related nahi usually — algo side Q.

SimpleBubble sort: adjacent swap, O(n²). Simple, slow. Viva rare — definition + complexity.

SimpleNormalisation: redundant data kam, tables todna. 1NF atomic, 2NF partial dep hatao, 3NF transitive dep hatao.

Viva tip

Exampleuser address alag table vs har booking mein dubara store.

Simplewatch = 'jab yeh badle tab yeh karo'. Computed nahi, kyunki return value nahi, kaam hai.

deep: true objects. immediate: true first run. Composition watch().

Search, $route.params.id load user.

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

watch(() => route.params.id, (id) => loadUser(id))

Project example: watch query debounce 300ms search API. Nahi use to 'computed kaafi'.

Simplev-if element DOM se hataata/jodata hai, v-show sirf CSS display toggle karta hai.

v-if='isAdmin' → false ho to element exist hi nahi. Costly toggle, lekin hidden data DOM mein nahi.
v-show='open' → display:none. Fast toggle, element hamesha DOM mein.

Rare condition: v-if. Bar-bar toggle (dropdown): v-show.

SimpleCamera pe clearly college/IITM ID dikhao — naam aur photo match hone chahiye.

Viva tipPehle se ID haath mein rakho, glare mat aane do. Iske baad GitHub + project run.

SimpleGitHub repo open karo: commits, collaborators, README. Examiner check karta hai tumne khud kaam kiya.

Example

Settings → Collaborators
Commits: regular messages, last-day dump nahi.

Viva tipPrivate repo access pehle de do. Main branch submitted ZIP se match honi chahiye.

Simplemodels.py = har table ki class: columns, PK/FK, relationships. Yeh Model layer hai.

Suggested flow1) Classes list karo
2) Har table ka kaam 1 line
3) Relationships (1-M / M-M)
4) Constraints (unique, nullable)

Example

class Lot(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    spots = db.relationship('Spot', backref='lot', lazy=True)

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.

Simpleasync function promise return karti hai. await us promise ka result wait karta hai — callback hell kam.

Example

async function loadLots() {
  const res = await fetch('/api/lots');
  const data = await res.json();
  return data;
}

SimpleMAD1 mein usually session-based auth: login pe session['user_id'], har request pe verify.

Example

session['user_id'] = user.id
uid = session.get('user_id')
user = User.query.get(uid)

Viva tipSECRET_KEY set karo warna session insecure. logout pe session.clear().

SimpleLifecycle = component ki zindagi ke stages. API call tab jab DOM ready ho — mounted.

created: instance bani, this data, DOM nahi. mounted/onMounted: page pe aa gaya — fetch, Chart.js, setInterval.
updated: data change ke baad. unmounted: cleanup (clearInterval) warna memory leak.

Dashboards onMounted isliye: canvas/API tab valid. created mein $el nahi.

Composition: onMounted(() => {}) setup ke andar.

Example

export default {
  async mounted() {
    const r = await fetch('/api/venues')
    this.venues = await r.json()
  }
}

Project example: Venues.vue mounted fetch list. Clock component unmounted pe interval clear.

Viva tipcreated: data setup, DOM nahi. mounted/onMounted: $el mil gaya — fetch yahi. Dashboards isliye onMounted use karti hain.

SimpleLive coding: notepad/editor mein chhota Flask route / Jinja loop / model field. Calm raho, run karke dikhao.

SimpleLive Flask coding: chhota route likho, save, browser/curl se test. Syntax error terminal mein padho.

Example

@app.route('/ping')
def ping():
    return jsonify(ok=True)

@app.route('/even/<int:n>')
def even(n):
    return 'even' if n % 2 == 0 else 'odd'

SimpleCamera pe clearly IITM/college ID dikhao — naam photo match.

Pehle se ID haath mein rakho. Glare mat aane do. Examiner screenshot/verify karta hai. Iske baad GitHub + project run.

Simpledata() local diary. Store school notice board.

Search query local. Logged-in user store. Persist: store + localStorage together.

state vs data: similar concept, scope alag.

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.

Example

// local
data() { return { q: '' } }
// global
this.$store.state.user

Project example: Login.vue local form fields. this.$store.state.user Navbar.

SimpleAJAX page reload ke bina server se data laata hai. Aaj kal fetch() + Promises.

fetch('/api/users').then(r => r.json()).then(data => { ... })
Promise: future value (pending/fulfilled/rejected). fetch Promise return karta hai.
SPA (Vue): ek HTML, baaki routes JS se, partial update. MAD1 generally full page render (Jinja) — submit pe poora refresh.
async/await Promise ka clean syntax.

SimpleServer-Sent Events: server → browser one-way stream (text/event-stream). WebSocket full duplex hai; SSE simpler notifications ke liye.

Example

# client
const es = new EventSource('/stream');
es.onmessage = (e) => console.log(e.data);
