SQL or NoSQL for my startup?

SQL (PostgreSQL, MySQL) for most applications—structured data, relationships, and ACID transactions. NoSQL (MongoDB) for document-oriented data or very flexible schemas. When in doubt, start with PostgreSQL—it handles almost everything well.

Supabase, PlanetScale, or Firebase?

Supabase is PostgreSQL with a great developer experience and built-in auth. PlanetScale is serverless MySQL with powerful branching. Firebase is NoSQL with real-time sync. Supabase is the popular default for new startups.

What is a managed database?

The provider handles servers, backups, updates, and scaling. You just use the database. Self-hosting means managing all that yourself. For startups, managed databases save time and reduce risk—worth the cost.

How much does managed database hosting cost?

Most services offer free tiers sufficient for development and early production. Supabase, PlanetScale, and Neon all have generous free plans. Paid plans start around $25/month and scale with usage.

What is PostgreSQL and why is it popular?

PostgreSQL is a powerful open-source relational database. It handles complex queries, JSON data, full-text search, and scales well. The ecosystem is mature with excellent tooling. It's the safe default for most applications.

What is serverless database?

Databases that scale to zero when idle and auto-scale with demand. You pay for actual usage, not always-on servers. Neon, PlanetScale, and Supabase offer serverless options. Great for variable workloads and cost control.

How do I back up my database?

Managed services handle automated backups—daily snapshots typically retained for 7-30 days. Point-in-time recovery lets you restore to any moment. Verify you understand your provider's backup policy and test restores occasionally.

What is database branching?

Creating isolated copies of your database for development or testing, like Git branches for code. PlanetScale pioneered this for databases. Enables safe schema changes and realistic testing without affecting production.

How do I handle database migrations?

Use migration tools to version control schema changes. Prisma, Drizzle, and framework-specific tools manage migrations. Never modify production schemas manually. Test migrations on branches or staging first.

What is an ORM and should I use one?

Object-Relational Mappers let you interact with databases using your programming language instead of SQL. Prisma and Drizzle are popular choices. ORMs speed development but learn some SQL too—you'll need it for complex queries.

How do I connect my app to the database?

Use connection strings (URLs) with credentials. Store these in environment variables, never in code. Connection pooling (built into most clients) handles multiple concurrent connections efficiently.

What about database performance?

Start simple—premature optimization wastes time. Add indexes for slow queries. Use query explain plans to understand performance. Managed databases handle most tuning. Optimize when you have actual performance data.

Should I use connection pooling?

Yes, especially for serverless environments where connections are created frequently. Supabase and PlanetScale include pooling. For others, use PgBouncer or similar. Pooling prevents connection limit issues.

What is edge database?

Databases distributed to edge locations for lower latency globally. Turso and some PlanetScale regions offer this. Important for global apps where latency matters. Most startups don't need edge initially.

How do I handle database security?

Use strong passwords, rotate credentials periodically, restrict network access, enable SSL connections, and follow least-privilege principles. Managed databases handle much of this, but understand your security model.

Can I switch databases later?

Possible but painful. Switching SQL databases (PostgreSQL to MySQL) requires migration work. Switching SQL to NoSQL is harder. Choose carefully initially, but don't overthink—PostgreSQL handles most needs.

What is Redis and when do I need it?

Redis is an in-memory data store for caching, sessions, and real-time features. You need it when database queries become a bottleneck or you need sub-millisecond access. Upstash offers serverless Redis.

How do I monitor database performance?

Managed platforms provide dashboards with query metrics, connection counts, and resource usage. Set up alerts for high usage. Tools like Datadog add deeper observability. Monitor before you have performance problems.

About This Problem

Every application needs to store data. Modern managed databases handle backups, scaling, and maintenance for you—so you can focus on building features instead of managing infrastructure.

You might have this problem if:

✓Building an app that needs to store user data
✓Not sure which database type to choose
✓Want managed infrastructure, not self-hosted
✓Need a database that scales with growth
✓Looking for developer-friendly tooling

Success Looks Like

Database provisioned and connected
Backups configured and verified
