Never Trust Users' Requirements

Never Trust Users' Requirements
The classic "just one small change" that breaks your entire data model. You design a perfect database with a unique constraint ensuring each user belongs to exactly one organization. The requirements were crystal clear. You even got it in writing. Then suddenly, the user who SWORE the relationship would "always be N:1" comes back asking if users can belong to multiple organizations. That look of horror is every database architect who now has to create a junction table, update all the queries, and pretend they're not dying inside. Next time, just assume every relationship is many-to-many from the start and save yourself the trauma.

Name Not Unique

Name Not Unique
When your parents named you "John" and now you can't even sign up for a developer account. Somewhere out there, a database administrator is smugly enforcing uniqueness constraints on first names like they're primary keys. Next thing you know, they'll be telling you your birthday has a foreign key violation because someone else already claimed December 25th.

The Government Doesn't Use SQL

The Government Doesn't Use SQL
OH MY GOD! Billionaire discovers basic database constraints and has a complete meltdown! 💀 The absolute DRAMA of someone who can launch rockets into space but apparently thinks the U.S. government is running their trillion-dollar operations on some janky SQL database without primary keys! Like, sweetie, I hate to break it to you, but the Social Security Administration isn't using phpMyAdmin they downloaded from SourceForge in 2003! It's giving "I just discovered databases exist and now I'm an expert" energy. Next revelation: the Pentagon doesn't store nuclear launch codes in an Excel spreadsheet! SHOCKING!
