Building a resilient application starts with enforcing business rules at the database level.
: Transition from sequential IDs to UUIDv7 for primary keys. Unlike random UUIDs, version 7 is timestamp-ordered, which significantly improves index locality and performance. 2. High-Performance Querying Mastering PostgreSQL in Application Development
To master PostgreSQL for application development, you must move beyond basic CRUD operations and leverage the engine's advanced features for data integrity, performance, and scalability. 1. Robust Schema Design Robust Schema Design : Always use Foreign Keys
: Always use Foreign Keys and Constraints (Primary, Unique, Check) to prevent data corruption before it reaches your application code. PostgreSQL Performance Tuning for Application Developers
: Use advanced constraints like EXCLUDE to prevent overlapping values (e.g., booking intervals) and GENERATED columns for automatic server-side calculations.
Mastering PostgreSQL means understanding how the query planner thinks. PostgreSQL Performance Tuning for Application Developers
