Database Design: From MongoDB to PostgreSQL
Database Design Guide
SQL vs NoSQL
### MongoDB (NoSQL) - Document-based - Flexible schema - Great for rapid development - Horizontal scaling with sharding
### PostgreSQL/MySQL (SQL) - Relational model - ACID compliance - Complex queries with JOINs - Strong data integrity
Normalization in SQL 1. **1NF**: Eliminate duplicate columns 2. **2NF**: Remove partial dependencies 3. **3NF**: Remove transitive dependencies 4. **BCNF**: Stronger form of 3NF
MongoDB Schema Design ```javascript // Embedded documents { _id: ObjectId, title: "Project", author: { name: "Pravin", email: "pravinpagar290@gmail.com" } }
// References { _id: ObjectId, title: "Project", authorId: ObjectId } ```
Indexing Strategy - Create indexes on frequently queried fields - Use compound indexes for multiple field queries - Monitor index performance - Balance between read speed and write performance
Common Patterns - User authentication tables - Audit logging - Soft deletes - Temporal data handling
