Database Engineering #
This section serves as the database entry point within the DevPro network.
It is designed to help engineers and architects navigate:
- Query planning and execution behavior
- Indexing strategies and performance trade-offs
- Reliability, scaling, and operational concerns
- Differences between database engines in real workloads
Rather than duplicating deep technical content here, DevProPortal directs readers to domain‑specific authority sites.
Primary Database Authority #
DatabaseDevPro.com #
DatabaseDevPro.com is the primary DevPro site for database engineering.
It focuses on:
- Reproducible performance labs
- Real
EXPLAIN / EXPLAIN ANALYZEoutput and metrics - Index design and execution plan reasoning
- Production-oriented trade-offs for PostgreSQL and MySQL
Featured Database Lab #
PostgreSQL: Index vs Full Scan (EXPLAIN ANALYZE) #
A hands-on PostgreSQL lab comparing:
- Full scan vs composite index
- 100k / 1M / 5M rows
- Execution plans, buffers, and scaling behavior
This lab demonstrates why correct index design outperforms parallel full scans at scale.
