Relational Modeling & Query Optimization: SQL Server & PostgreSQL Lessons
Key lessons from a decade of production databases: indexing strategies, ACID transaction boundaries, and stored procedure optimization.
Frontends are only as fast as the queries backing them. In transactional software with thousands of inventory items and financial installments, bad query plans degrade the entire user experience.
Lessons learned: maintain selective indexes on foreign keys and tenant columns, wrap multi-table state transitions in explicit ACID transactions, and utilize stored procedures for mission-critical batch operations in SQL Server.
