PostgreSQL vs SQLite

Difference between PostgreSQL & SQLite.

PostgreSQL
It is an object-relational database management system (ORDBMS) that is compatible with various SQL features. It follows the transaction along with the ACID (Atomicity, Consistency, Isolation, and Durability) properties. It provides the complete support for foreign keys, View, Joins, Triggers, and Stored procedures.

SQLite
“It is an embedded, relational database management system. It has a stable file format. It is cross-platform that why it can be run on various platforms.
And it required zero configuration and transactional SQL database engine.”
