2. What is SQLite?
● SQLite is a software library that provides a relational database management
system. The lite in SQLite means lightweight in terms of setup, database
administration, and required resources.
● SQLite has the following noticeable features: self-contained, serverless, zero-
configuration, transactional.
● It is not a standalone app; rather, it is a library that software developers
embed in their apps.
For Flutter: We use this sqflite package to perform SQL queries.
