SQLite database Android Studio Java
Introduction to SQLite in Android Programming (Java)
What is SQLite?
SQLite is a lightweight, embedded, relational database used in Android applications for local data storage. It is serverless, self-contained, and requires minimal setup, making it ideal for mobile applications.
Features of SQLite in Android**
✔ **Lightweight & Fast – No server setup needed.
✔ **ACID-Compliant – Ensures reliable data transactions.
✔ **Open Source – Free to use in any application.
✔ **Embedded Database – Stored within the app, requiring no external configuration.
✔ **Uses SQL Queries – Supports standard SQL commands like `SELECT`, `INSERT`, `UPDATE`, `DELETE`.
How SQLite Works in Android?
Android provides the `SQLiteDatabase` class to manage database operations. Developers interact with SQLite using SQL queries or through Android’s built-in APIs like *Room Database (Recommended for Modern Development).*
Basic Steps to Use SQLite in Android (Java)
1️⃣ *Create a Database Helper Class* (`SQLiteOpenHelper`)
2️⃣ *Define Tables and Columns*
3️⃣ *Override `onCreate()` & `onUpgrade()` Methods*
4️⃣ *Perform CRUD Operations* (`Create, Read, Update, Delete`)
5️⃣ *Use `SQLiteDatabase` Object to Execute Queries*
Conclusion
✔ SQLite is a powerful built-in database for Android apps.
✔ Ideal for storing small to medium-sized data locally.
✔ Use Room Database for modern and efficient database management in Android.
