雅虎開源用于 Android 的 SQLite 數據庫框架：SquiDB

SquiDB是一個用于Android的SQLite數據庫層。它的目的是讓盡可能容易地使用SQLite數據庫，同時還能利用原生SQL的強大和靈活性。SquiDB采用面向對象的方式來構建SQL語句，使其易于閱讀和沒有一堆凌亂的SQL字符串。

// This is a table schema
@TableModelSpec(className = "Person", tableName = "people")
public class PersonSpec {

    // A text column named "firstName"
    public String firstName;

    // A text column named "lastName"
    public String lastName;

    // A long column named "creationDate", but referred to as "birthday"
    // when working with the model
    @ColumnSpec(name = "creationDate")
    public long birthday;
}

// This is how you'd set up a database instance
public class MyDatabase extends AbstractDatabase {

    private static final int VERSION = 1;

    public MyDatabase(Context context) {
        super(context);
    }

    @Override
    protected String getName() {
        return "my-database.db";
    }

    @Override
    protected Table[] getTables() {
        return new Table[]{
            // List all tables here
            Person.TABLE,
        };
    }

    @Override
    protected int getVersion() {
        return VERSION;
    }

    // Other overridable methods exist for migrations and initialization;
    // omitted for brevity
}

DatabaseDao dao = new DatabaseDao(new MyDatabase(context));

// This is how you'd work with the generated model
Person newPerson = new Person()
    .setFirstName("Sam")
    .setLastName("Bosley")
    .setBirthday(System.currentTimeMillis());
dao.persist(newPerson);

...

String firstName = newPerson.getFirstName();
String lastName = newPerson.getLastName();
long birthday = newPerson.getBirthday();
