Document Database Basics

Relational Databases

• SQL Databases: Data stored in rows & columns, similar to spreadsheets
• Separate Tables: Related data stored in separate tables to prevent duplication
• Example:
  • Users table
  • Phone numbers table related to users via user IDs
  • Queries require joining tables to get related data

Document Databases

• MongoDB: Data stored in JSON documents
• JSON: JavaScript Object Notation, key-value pairs, very flexible
  • Stores many data types: strings, numbers, booleans, arrays, nested objects
• Single Document: Related data stored together, eliminating need for separate tables
• Example Syntax: JSON formatted data
