Database Design Best Practices
- Always have a primary key — every table needs a reliable way to uniquely identify each row.
- Add created_at and updated_at — timestamp columns are invaluable for debugging and auditing.
- Use NOT NULL wherever possible — NULL values complicate queries and indexes.
- Index foreign key columns — columns used in JOIN conditions should always be indexed.
- Use DECIMAL for money — never use FLOAT or DOUBLE for financial calculations.
