What is SQLite3 Library?

SQL dialects are variations of SQL (Structured Query Language) developed by different database vendors. While all are based on standard SQL, each dialect has unique features, additional functions, or specific syntax elements. This allows for the use of specialized capabilities in certain database management systems (DBMS).

SQLite3 Library

In this course, we will use the Python library sqlite3 to work with SQLite databases. It is a very convenient library because it is one of Python's standard libraries, and we don't need to install anything extra to work with it.

The key features and capabilities of the sqlite3 library include:

• Connecting to a Database: you can establish a connection to an SQLite database and open it for further operations;

• Creating Tables: you can create new tables in the database, defining their schemas and columns;

• Executing SQL Queries: you can execute SQL queries, such as SELECT, INSERT, UPDATE, and DELETE, to retrieve, update, and delete data from tables;

• Parameterized Queries: you can use parameterized queries for safely inserting data into tables and preventing SQL injection;

• Transactions: the sqlite3 library supports transactions, allowing you to group multiple operations into a single atomic operation;

• Reading and Writing Database Files: you can read and write SQLite database files;

• Exception Handling: the library provides mechanisms for handling errors and exceptions during interactions with the database.
