Most Popular Database Management Systems

About This Dataset

This chart shows the most popular database management systems by their DB-Engines popularity score (February 2026), a measure based on search frequency, job postings, technical discussion and professional profiles.

✨ AI Insight

Oracle remains the most popular database management system with a DB-Engines score of 1204, a position it has held since 2012, followed by the open-source MySQL at 868. Microsoft SQL Server and PostgreSQL sit close together at 708 and 672, with PostgreSQL widely reported as the fastest-growing of the leaders. All four of these top systems are relational databases, underlining the continued dominance of the traditional table-based model. The one document-oriented system in the top five, MongoDB at 379, trails the relational leaders by a wide margin, reflecting how NoSQL databases serve important but more specialised needs. The gap between Oracle and MongoDB shows that despite decades of new database technologies, established relational engines still command the largest share of professional attention.
