When Proper Database Design Kills Startups | HackerNoon

Senior engineers kill startups by applying enterprise database practices to Complex domains. Traditional normalization assumes stable requirements and migration infrastructure, but startups have neither.

You keep ACID guarantees and relational integrity while shipping features in days instead of waiting weeks for schema migrations.
