PostgreSQL
PostgreSQL (often shortened to Postgres) is an advanced open-source relational database system known for its strict compliance with SQL standards and powerful features. It supports complex queries, advanced data types, full-text search, and even geospatial data. Many large-scale, mission-critical applications rely on PostgreSQL due to its reliability and flexibility. For non-technical readers, PostgreSQL is like a "Swiss Army knife" of databases: it can do everything a traditional database does, but it also supports advanced and unusual workloads—like mapping, analytics, and scientific applications—all while being free and open-source.
