Strategy
Migrating from Relational to NoSQL for a Social Media Startup
Overview
What this challenge is about.
You are given a simplified relational schema of SnapVibe's current database (users, posts, comments, likes). Your task is to: (1) analyze the limitations of the relational model for their use case, (2) design a document-based schema in MongoDB that optimizes for read/write performance and flexibility, (3) write a script to migrate a sample dataset from the relational to the NoSQL schema, and (4) produce a report comparing the two approaches. Success means a working migration script and a clear rationale for the chosen NoSQL design. Constraints: use only MongoDB and a provided sample dataset.
The Brief
What you'll do, and what you'll demonstrate.
