Database Design Why Your Data Models Are Probably Broken
Something I've noticed recently is how many developers treat database design like an afterthought. They'll spend weeks perfecting the user interface or the API endpoints, but when it comes to the data layer, it's all "we'll figure it out as we go." Then six months in, they're dealing with performance nightmares, data inconsistencies, and migrations that take longer than the original development.
A friend in engineering told me last week about their team's latest debacle: They built a beautiful e-commerce platform, but the database couldn't handle the order volume during their first big sale. Queries took minutes, customers abandoned carts, and they lost thousands in revenue. All because they didn't think through the relationships and indexing properly.
The real issue? Most database designs are reactive, not proactive. We model data based on today's requirements without considering how it will grow, change, or perform under load.
