PostgreSQL
Following adds this technology to your private workspace so related learning is easier to organise and revisit.
What is PostgreSQL?
PostgreSQL is an open-source relational database known for standards support, extensibility and strong transactional behaviour. This profile connects the concept to KBY's practical engineering guidance.
It provides SQL, multi-version concurrency control, rich indexing, replication and extensible data types and functions. Production reliability depends on schema and query design, vacuum behaviour, backups, connection management and a deliberate high-availability topology.
Store and query complex transactional relational data reliably.
- Complex relational databases
- Geospatial data (PostGIS)
- Transactional application backends
