| Brief description |
ArangoDB is a native multi-model database system developed by ArangoDB Inc. The database system supports three data models (key/value, documents, graphs) with one database core and a unified query language AQL (ArangoDB Query Language). |
PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. It can handle workloads ranging from small single-machine applications to large Internet-facing applications (or for data warehousing) with many concurrent users; on macOS Server, PostgreSQL is the default database and it is also available for Microsoft Windows and Linux (supplied in most distributions).
PostgreSQL is ACID-compliant and transactional. PostgreSQL has updatable views and materialized views, triggers, foreign keys; supports functions and stored procedures, and other expandability.
PostgreSQL is developed by the PostgreSQL Global Development Group, a diverse group of many companies and individual contributors.It is free and open-source, released under the terms of the PostgreSQL License, a permissive software license. |
