While you can write raw SQL, most modern developers use abstraction layers that map database rows to objects:
There is no setup required. The database is "just there" once the library is linked to your project.

It is the default database for both iOS (Core Data uses SQLite under the hood) and Android (Room Persistence Library) . Enabling the "Offline-First" Strategy
SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. Unlike traditional databases like PostgreSQL or MySQL, SQLite is . The database engine is integrated directly into the mobile application, meaning there is no separate server process to install, configure, or manage. The entire database is stored as a single, cross-platform file on the device’s disk. Why Mobile Developers Choose SQLite While you can write raw SQL, most modern
SQLite is designed to operate within the strict memory and battery constraints of mobile hardware. It can handle massive datasets with a tiny footprint.
The primary advantage of SQLite is its ability to enable development. Instead of showing a loading spinner while fetching data from a network, the app displays data immediately from the local SQLite cache. Any user changes are written to the local database first and then synchronized with the server when a connection is restored. This eliminates "network jitter" and makes the app feel instantaneous.
