Episode 12 — Build Database Logic Safely: Views, Stored Procedures, and User-Defined Functions
This episode teaches how database-side logic supports consistency, security, and performance, while also introducing operational risks that DS0-001 expects you to manage. You’ll define views as reusable query abstractions that can simplify access patterns and support least privilege by exposing only approved columns or rows, then compare that to stored procedures as controlled execution units that bundle logic, enforce validation, and reduce application-side complexity. We’ll cover user-defined functions and how they can improve clarity and reuse, while also becoming a hidden performance problem if they are executed row-by-row or prevent index usage. You’ll practice deciding when logic should live in the database versus in the application, with attention to testing, version control, dependency tracking, and rollback planning. Realistic examples will include securing sensitive fields through view design, standardizing a multi-step update in a stored procedure to reduce partial failures, and troubleshooting a sudden slowdown traced to a function used inside a predicate.
