🗄️ is SQLite3?

SQLite3 is a Relational Database Management System - RDBMS that is very special and popular because it is an Embedded or Serverless database.

Definition: SQLite is not a standalone application that requires a separate server (like MySQL or PostgreSQL) to be installed, but a library (library) embedded directly into the application itself.

Storage format: All databases (tables, data, indexes) are stored in a single file, on the user's disk (typically a file with a extension such as .db or .sqlite).

In other words, SQLite is the most widely used database engine in the world because it is embedded in many software and devices such as web browsers (Firefox, Chrome), mobile operating systems (Android, iOS), and small desktop software.

👍 The main advantages of SQLite3

SQLite has several advantages that make it suitable for specialized applications:

1. ⚙️ No server required (Serverless)

Ease: No Server Process required to run behind the scenes. No installation, setup, or maintenance of complex servers.

Connection: Connecting to a database is simple, just open and read the database file directly.

2. 💨 Lightweight & Fast (Lightweight & Fast)

Small: The library itself is very small (about 500 KB to 1 MB), making it ideal for embedding in devices with limited resources such as mobile, IoT, and embedded systems.

Performance: For data reading (Read Operation) is usually faster than server-based databases in low to moderate use environments.

3. 💾 Easy storage

Single file: All data is included in a single file, making it easy to store, copy, move, or back up (just Copy files).

Cross-Platform: Database files can be instantly copied to use on different operating systems (e.g. built on Linux and then opened on Windows).

4. 🔬 Suitable for Development & Testing

Developers often use SQLite as a database for Local Development (local development) and Unit Tests runs because it's easy to install and quick to get started.

5. 🛡️ ACID support (Transaction Compliance)

Even though it is a small database, SQLite still supports ACID (Atomicity, Consistency, Isolation, Durability) features, ensuring that transactions (Transactions) are accurate and reliable.
