Concurrency: Use Postgres to achieve concurrency in your database, it is versatile in terms of architecture (CRUD, System of Records, OLTP and also OLAP, Analytics, Dashboards), and is powerful in terms of computation.ģ. PostgreSQL supports different kinds of techniques for geographic data storage such as PostGIS, Key-Value Store, and DBLink.Ģ. Using extensions like PostGIS, where you can implement geospatial joins and get exactly the data you need even when your problem requires being smart about the data location on a map. ![]() Extensions: With Postgres, we have access to lots of extensions that will enable new ways to process data right from the database.

The MVCC feature in PostgreSQL is known as snapshot isolation in Oracle. PostgreSQL is the first database management system that completely implements a multi-version concurrency control (MVCC) feature, even before Oracle.

PostgreSQL was designed and developed to run on UNIX-like systems. PostgreSQL was developed initially based on POSTGRES 4.2 at the Berkeley Computer Science department at the University of California. PostgreSQL is an all-purpose and object-relational database management system, and it is the most advanced open-source database system.
