What are the differences between Heroku's database options?

Heroku offers several database options like PostgreSQL, Redis, and MongoDB. PostgreSQL is a relational database, great for structured data, while Redis is an in-memory data store, ideal for caching and real-time analytics. MongoDB is a NoSQL database, suitable for unstructured data.

Which one is the best for a new web application?

It depends on your application's needs. If you require complex queries and transactions, PostgreSQL is a solid choice. For real-time data processing, Redis is excellent. If you're dealing with large amounts of unstructured data, MongoDB might be the way to go.

Can I use multiple databases in one app?

Yes, you can use multiple databases in a single Heroku app. Just ensure that your application logic can handle the different data models and access patterns.

What are the costs associated with each database?

Costs vary based on the database type and usage. PostgreSQL has a free tier, but costs increase with performance and storage. Redis and MongoDB also offer free tiers, but pricing can escalate with additional features and scaling.
