MongoDB Learning Path with Timeline
Understand what databases are (SQL vs NoSQL).
Learn about MongoDB: features, advantages, use cases.
Install MongoDB locally or use MongoDB Atlas (cloud).
Learn MongoDB tools: mongosh (shell), Compass (GUI).
Week 2: Core MongoDB Operations
Learn about databases, collections, and documents.
CRUD operations:
Insert (insertOne, insertMany)
Read (find, query filters, projections)
Update (updateOne, updateMany, $set, $inc)
Delete (deleteOne, deleteMany)
Practice simple queries on sample datasets.
Week 3: Query Operators and Indexing
Learn query operators: $eq, $gt, $lt, $in, $and, $or.
Sorting and limiting results.
Indexes: single-field, compound, text, geospatial.
Performance benefits of indexes.
Week 4: Aggregation Framework
Understand pipelines and stages ($match, $group, $sort).
Common operations: $sum, $avg, $count, $lookup (joins).
Practice with real-world examples like sales data or logs.
Week 5: Schema Design & Data Modeling
Schema design principles in MongoDB (flexibility vs structure).
Embedding vs referencing documents.
One-to-one, one-to-many, many-to-many relationships.
Best practices for designing collections.
Week 6: Advanced Features
Transactions and atomic operations.
Replication basics (Replica sets, high availability).
Sharding concepts (horizontal scaling).
Security: authentication, authorization, roles.
Week 7: MongoDB with Applications
Connect MongoDB with Node.js (Mongoose ODM).
Perform CRUD from an app.
Practice building a small project (e.g., task manager, blog).
Week 8: Optimization & Deployment
Query performance analysis (explain()).
Indexing strategies for large data.
Backup and restore.
Deploying MongoDB on Atlas with cloud best practices.
By following this 8-week roadmap, you’ll gain a solid understanding of MongoDB from basic CRUD operations to advanced features like aggregation, indexing, replication, and sharding. More importantly, you’ll also learn how to design schemas, integrate MongoDB with applications, and optimize performance for real-world projects. At the end of your journey, you should be ready to build and deploy full-fledged applications using MongoDB as a core database technology.
