Заготовка для работы с SQLite в Android

Маленький шаблон, для работы с SQLite:

public class DBAdapter 
{
	private static final String DATABASE_NAME = "test";
	private static final int DATABASE_VERSION = 1;

	private final Context context;
	private DatabaseHelper DBHelper;
	private SQLiteDatabase db;

	public DBAdapter(Context ctx)
	{
		this.context = ctx;
		DBHelper = new DatabaseHelper(context);
	}
	private static class DatabaseHelper extends SQLiteOpenHelper
	{
		DatabaseHelper(Context context)
		{
			super(context,DATABASE_NAME, null, DATABASE_VERSION);
		}

		@Override
		public void onCreate(SQLiteDatabase db) {
			// TODO Auto-generated method stub

		}

		@Override
		public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
			// TODO Auto-generated method stub

		}
	}
	public SQLiteDatabase GetDataBaseOpen() throws SQLException
	{
		return this.db;
	}
	public DBAdapter Open() throws SQLiteException
	{
		db = DBHelper.getWritableDatabase();
		return this;
	}
	public DBAdapter OpenForRead() throws SQLiteException
	{
		db = DBHelper.getReadableDatabase();
		return this;
	}
	public void Close() 
	{
		DBHelper.close();
	}
}
