Getting started with SQLite


SQLite is an open-source database that is lightweight compared to other databases. It is really efficient in terms of performance as the entire database is packaged and stored as a single file within our file system. It has most of the standard SQL features like transactions, support for triggers, views, and primary and foreign key constraints. It is widely used, and most of Android applications use SQLite as the database. The entire source code for the database is publicly available.

sqlite dynamic

SQLite uses dynamic typing. Even though we define types for columns, but still any type of data can be stored in any column. Types are resolved based on data and there is no type safety.

Backup\ Loading of Database

Use .backup command as seen below to take a backup of Main db.
