Databases
SQL, NoSQL, design patterns, and database optimization
📚Curriculum Overview
SQL Fundamentals
Master the core SQL commands every developer must know — SELECT, INSERT, UPDATE, DELETE — with real examples.
Database Design & Normalization
Design efficient, scalable relational databases using normalization, keys, and relationships.
Joins & Complex Queries
Combine data from multiple tables using JOINs, subqueries, CTEs, and window functions.
Indexes & Query Performance
Master database indexing to make queries 100x faster — and know when NOT to add indexes.
NoSQL Databases
Understand NoSQL's document, key-value, column, and graph models — and know when to choose NoSQL over SQL.
Transactions & ACID Properties
Guarantee data integrity with ACID transactions — the bedrock of reliable database operations.
Database Migrations
Manage schema changes safely across environments using versioned migrations and rollback strategies.
Backup & Disaster Recovery
Protect your data with automated backups, point-in-time recovery, and tested disaster recovery plans.
Database Scaling
Scale your database from hundreds to millions of users with replication, sharding, and caching strategies.
Database Monitoring & Maintenance
Keep your database healthy with proactive monitoring, slow query analysis, and routine maintenance.
🏆Capstone Project
Build a Production-Ready Blog Database
Design and implement a complete blog platform database from scratch: schema design with normalization, full-text search indexes, stored procedures for analytics, transaction-safe comment voting, Redis caching layer for popular posts, and a monitoring dashboard showing slow queries and cache hit rates. Write migrations for each step and include rollback scripts.
