I use PostgreSQL, known as the world’s most advanced open-source relational database, as the primary data store for my Phoenix applications. Its robust features and standards compliance make it an excellent choice for handling complex data requirements.

PostgreSQL supports advanced data types, powerful querying capabilities, and strong transactional integrity, which are crucial for building reliable and scalable applications. Additionally, its extensibility allows me to leverage custom functions and integrations, ensuring that my applications can grow and adapt to changing needs while maintaining optimal performance.
