The system that stores an app's data in an organized, permanent way, such as users, orders and products, and lets you query and update it.
A database is an app's long-term memory. Every user account, order, product and appointment is stored there in an organized way so it can be retrieved quickly. Among the most common kinds are relational databases such as PostgreSQL, which organize data into tables.
Choosing, structuring and protecting the database is one of the most important decisions in any app, because data is your most valuable asset. You need backups, tight access permissions, encryption and clarity about where it is stored, especially under data protection laws. Fanann offers a managed database for this. Practical tip: think about data before screens: what are the core entities in your business and how do they relate? Make sure you can export all of your data whenever you want; it protects you from lock-in.
