PostgreSQL

PostgreSQL is an open-source relational database known for reliability, strict standards compliance and rich capabilities. It supports ACID transactions, complex queries, JSON documents, full-text search and extensions, which allows covering a wide range of tasks in one system.

PostgreSQL is chosen for payment systems, accounting and analytics services, platforms with high data integrity requirements and projects with complex relationships between entities. Replication, partitioning and thoughtful indexing keep performance predictable at scale.

At Dev48 we use PostgreSQL as the primary database for most projects: we design schemas and migrations, optimise queries and indexes, configure replication and backups, and ensure security and access control.
