NoSQL (MongoDB, Redis)
NoSQL (MongoDB & Redis) Mastery Roadmap
This detailed roadmap will take you from beginner to expert in NoSQL databases, covering MongoDB (document-based storage) & Redis (in-memory key-value store) for scalable, high-performance applications.
Phase 1: NoSQL Fundamentals
✅ Introduction to NoSQL
What is NoSQL? Why use it over SQL?
Differences between Document, Key-Value, Column, and Graph Databases
Comparing MongoDB vs. Redis vs. SQL
✅ MongoDB Basics
Installing & Setting Up MongoDB
MongoDB Data Model (JSON/BSON)
CRUD Operations (
insertOne,find,updateOne,deleteOne)
✅ Redis Basics
Installing & Running Redis
Redis Data Types: Strings, Lists, Sets, Hashes, Sorted Sets
Basic Commands (
SET,GET,EXPIRE,HSET,LPUSH)
📌 Mini Projects:
Building a Simple User Data Store in MongoDB
Implementing a Redis Cache for API Responses
Phase 2: Advanced MongoDB
✅ Querying & Indexing
Filtering & Projections (
$gt,$lt,$in,$regex)Sorting & Pagination (
sort(),skip(),limit())Indexing for Performance (
createIndex(), compound indexes)
✅ Schema Design & Relationships
Embedded Documents vs. References
One-to-One, One-to-Many, Many-to-Many Relationships
✅ Aggregation Framework
$match, $group, $sort, $lookup
Pipeline Optimization for Large Datasets
📌 Mini Projects:
Building a Product Catalog (with Filtering & Sorting)
User Analytics Dashboard using Aggregation Pipeline
Phase 3: Advanced Redis & Caching Strategies
✅ Using Redis for Performance Optimization
Redis as a Cache Layer (LRU, TTL, Eviction Policies)
Session Management (JWT, OAuth, Authentication Tokens)
✅ Advanced Redis Operations
Pub/Sub for Real-Time Messaging
Redis Streams & Sorted Sets for Event Processing
Lua Scripting in Redis
📌 Mini Projects:
Building a Real-Time Chat System with Redis Pub/Sub
Implementing Rate Limiting for API Requests
Phase 4: NoSQL in Production
✅ MongoDB Performance Tuning
Sharding & Replication
MongoDB Transactions & ACID Compliance
Security: Authentication, Role-Based Access Control (RBAC)
✅ Redis for High Availability
Redis Sentinel & Cluster Setup
Persistent Storage with AOF & RDB Snapshots
Security: Access Control, Encryption, Firewall Rules
📌 Mini Projects:
Scaling a High-Traffic Web Application with MongoDB & Redis
Implementing a Full-Text Search Engine with MongoDB
Phase 5: Real-World Projects & Integration
✅ Using NoSQL with Backend Frameworks
Node.js (Mongoose for MongoDB, ioredis for Redis)
Python (PyMongo, redis-py)
✅ Final Projects & Portfolio Building
E-commerce System with MongoDB (Orders, Users, Products, Payments)
Real-Time Leaderboard using Redis Sorted Sets
High-Performance Logging System (Redis + MongoDB)
Final Step: Real-World Practice & Skill Testing
