You may hear the expression “CRUD” used in relation to databases. And if you haven't, you have now. CRUD is a acronym for Create, Read, Update, and Delete—the four main operations that are done on databases.

The book consistently uses “a” as the indefinite article ahead of “SQLite”—most probably because they assume a pronunciation of “sequel lite.” The primary author of “SQLite” sees things differently, so the indefinite article should be “an”.

StarbuzzDatabaseHelper.java

package com.hfad.starbuzz;
 
import android.database.sqlite.SQLiteOpenHelper;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
 
class StarbuzzDatabaseHelper extends SQLiteOpenHelper {
 
    StarbuzzDatabaseHelper(Context context) {
        // This constructor isn't liked by the compiler.
        // It'll be fixed shortly.
    }
 
    @Override
    public void onCreate(SQLiteDatabase db) {
    }
 
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    }
}

Note that the constructor in the above class definition creates compiler rage. It gets fixed on the following page.
