A new column changes everything

When you add a new column, you are altering the contract between storage and code. In SQL, it means adjusting the table definition with ALTER TABLE ADD COLUMN. In NoSQL, it means shaping documents to accept the field without disrupting existing reads. In data warehouses, it requires updates to ETL
