What is PostgreSQL and why is it important?
PostgreSQL is one of the most advanced open source relational database system. It is characterized by many features that help developers build applications, administrators to protect data integrity and help data analyst and data scientist to manage their data regardless of the size of the dataset.
What makes PostgreSQL better than MySQL?
PostgreSQL is an object-relational database, while MySQL is purely relational. This means PostgreSQL offers more complex data types and allows objects to inherit properties, but it also makes working with PostgreSQL more complex. PostgreSQL has a single, ACID-compliant storage engine.
Is PostgreSQL still relevant?
PostgreSQL’s popularity is still growing. Among systems used by professionals, PostgreSQL came second, ahead of giants like Microsoft SQL Server, MongoDB, Oracle, and Redis.

What is PostgreSQL and its features?
PostgreSQL is an object-relational database management system (ORDBMS). It contains the various advanced data types and robust feature sets, which increase the extensibility, reliability, and data integrity of the software.
Why is PostgreSQL so popular?
features and performance as well as scalability make it a proper alternative for applications where traditionally Oracle DB was hard to replace. its more recent features for Key-Value-Storage (JSON / JSONB column type) make it an alternative to NoSQL-databases. PostgreSQL supports clustering / Master-Slav.
What makes Postgres different?
PostgreSQL isn’t just relational, it’s object-relational. This gives it some advantages over other open source SQL databases like MySQL, MariaDB and Firebird. This makes PostgreSQL extremely flexible and robust. Among other things, complex data structures can be created, stored and retrieved.
