SQLITE DATABASE

2. Introductory part about SQLITE
 SQLite is a self-contained, server less, and zero-configuration relational
database management system (RDBMS).
 It is designed to be embedded into applications, providing a lightweight
and efficient way to store and manage data.
 SQLite is a popular choice for many applications, including mobile apps,
desktop applications, embedded systems, and web applications

3. Key Features of SQLITE
 Server less
 Zero-configuration
 Relational database: SQLite supports standard relational database
features, including:
- Tables
- Indexes
- Views
- Transactions

4. Key Features of SQLITE
 ACID compliance: SQLite follows the Atomicity, Consistency, Isolation, and
Durability (ACID) principles, ensuring that database transactions are
processed reliably
 Atomicity
 Consistency
 Isolation
 Durability

5. Advantages of SQLITE
 Lightweight
 Fast
 Easy to use
 Low overhead

6. Creating and opening Database
 Creating and Opening a Database
 The SQLiteOpenHelper class helps in database management.
 onCreate() → Called when the database is created for the first time.

7. Creating Tables
• A table in SQLite consists of columns (fields) with specific data types.
Common Data Types in SQLite: INTEGER → Stores whole numbers.
• TEXT → Stores text values.
• REAL → Stores floating-point numbers.
• BLOB → Stores binary data.

8. Creating tables code
public void onCreate(SQLiteDatabase db) {
String CREATE_TABLE = "CREATE TABLE students (id INTEGER PRIMARY KEY,
name TEXT, age INTEGER)";
db.execSQL(CREATE_TABLE);
}

9. Inserting Data
 Data is inserted using the insert() method or raw SQL queries.

10. Inserting Data Codes
public void insertStudent(String name, int age) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("name", name);
values.put("age", age);
db.insert("students", null, values);
db.close();
}

11. Retrieving Data
 Data is retrieved using the query() method or raw SQL queries.

12. Retrieving Data Code
public Cursor getAllStudents() {
SQLiteDatabase db = this.getReadableDatabase();
return db.rawQuery("SELECT * FROM students", null);
}

13. Deleting Data
 The delete() method removes specific records.

14. Deleting Data Code
public void deleteStudent(int id) {
SQLiteDatabase db = this.getWritableDatabase();
db.delete("students", "id=?", new String[]{String.valueOf(id)});
db.close();
}
