PostgreSQL vs. SQLite: Choosing the Right Database
PostgreSQL and SQLite are both powerful, open-source relational database management systems (RDBMS), but they cater to different needs. This comparison highlights their key differences to help you choose the best option for your project.
Understanding SQLite
SQLite is an embedded database—it's designed to be integrated directly into your application, without needing a separate server process. It's lightweight, easy to set up, and requires minimal configuration. It stores data in a single file, making it very portable. It's cross-platform, working on Windows, various Unix-like systems, and mobile operating systems.
