Windows users can run the sqlite3.exe executable file, which will open a new shell running SQLite. On Mac or Linux a new SQLite session can be initiated by navigating to a terminal (e.g., Terminal on MacOS) and running sqlite3. Once SQLite is installed on your machine, open a new SQLite session. Aside from its ability to easily connect to a SQLite database file, as well as other SQL engines, DbVisualizer is also used here because it contains a visually appealing and easy-to-use query editor with syntax highlighting. DbVisualizerĭbVisualizer is a popular tool for connecting to multiple SQL engines and databases, including SQLite. An added benefit of SQLite is that databases can be stored locally as files on your computer (these files have a “.db” extension).

Knowing Structured Query Language, or SQL, is foundational for various data professions, including data analysts, data engineers, and data scientists.
