Introduction to SQL, SQLite CLI Program, and SQLite3 Python Library (Pt 1: Concepts and Tables)
In this first part of the series, we dive into the world of SQL and SQLite by covering core concepts, how to use the SQLite CLI (command-line interface), and how to interact with SQLite databases using Python’s built-in sqlite3 library.
You’ll learn:
What SQLite is and how it differs from other databases
What a database and table are, and how they relate
How to create and explore databases using terminal and Python side-by-side
The basics of SQL commands like CREATE TABLE, INSERT, SELECT, UPDATE, and ALTER
How to use SQL data types like INTEGER, REAL, TEXT, and DATE
The role of primary keys and the importance of unique identifiers
The difference between WHERE and conditional modifiers like IF EXISTS
Practical examples of creating, modifying, and viewing data using both CLI and Python
Whether you're using a Raspberry Pi, Mac, or any other platform, you'll walk away with a strong foundational understanding of SQLite and be ready for more advanced (and fun) topics in Part 2!
