SYS.DETAIL

OVERVIEW

PostgreSQL is the backbone of our backend infrastructure. As the world's most advanced open-source relational database, it offers features that rival commercial databases costing tens of thousands — JSONB for flexible document storage, full-text search, row-level security, and ACID compliance for bulletproof data integrity.

At DMC Kreatif, PostgreSQL powers every Supabase project we build. Its Row-Level Security (RLS) policies are essential for GDPR compliance, ensuring that users can only access their own data — enforced at the database level, not just the application layer. This defence-in-depth approach is critical for European businesses handling personal data.

PostgreSQL's performance at scale is exceptional. With proper indexing, it handles millions of rows with sub-millisecond query times. Its JSON support lets us store flexible, schema-less data alongside relational data, giving us the best of both SQL and NoSQL worlds.
