Database Schema with AI: Migrations Without Disasters

Welcome to Day 15 of the Vibe Coding series from Mudiri Digi. Database Schema with AI: Migrations Without Disasters — a practical guide for global developers building digital products with AI assistance.

ER modeling

An overview of ER modeling in the vibe coding context: how AI shortens dev time without sacrificing baseline quality.

• Define the goal before opening your editor
• Write a clear prompt with project context
• Review output line by line

Migration strategy

A practical take on Migration strategy: steps you can run today with Cursor or Claude on a real project.

• Split work into 25-minute steps
• Use diff view before merging
• Document the decision in README

Indexes

Common mistakes around Indexes — and how to avoid them on small or solo dev teams.

• Never trust AI for secrets or auth
• Run linter and tests after each session
• Keep a rollback copy

Seed data

Success metrics for Seed data: what to measure before and after applying this lesson.

• Measure delivery time vs quality
• Log what worked in a prompt library
• Share results with the team

Review checklist

Advanced steps for Review checklist when the project grows or new developers join.

• Plan a weekly refactor slot
• Automate CI/CD gradually
• Review architecture decisions

Daily execution checklist

1. Read the article and pick 3 points that apply to your current project.
2. Apply the database schema AI design lesson in a 45–90 minute vibe coding session.
3. Review generated code: security, naming, and tests.
4. Merge changes via a clear Git commit.
5. Log what you learned — for the next day in the series.

Frequently asked questions

What is vibe coding and how is it different from traditional programming?

Vibe coding blends developer intuition, AI tools, and a steady daily rhythm to ship features with acceptable quality. The focus is fast delivery with human review — not blind copy-paste of generated code.

Is Day 15 content suitable for beginners?

Yes. Every Mudiri Digi article in this series is practical: clear concepts, an execution checklist, and cited sources. Start at Day 1 if you are new to vibe coding.

What tools do I need to get started?

An editor like Cursor or VS Code, a GitHub account, and an AI model (Claude or Copilot). You do not need a complex stack — start with a small project and apply today's lesson.
