How to Add a New Column Without Breaking Production

A new column changes everything in a relational database. It can hold fresh data, enable new logic, or replace brittle joins. Done right, it sharpens performance. Done wrong, it breaks production. The difference is process. First, define the purpose. Every new column must have a clear role. Avoid vague names.
