<!DOCTYPE database SYSTEM "litesql.dtd">
<database name="PersonDatabase">
    <object name="Person">
        <field name="name" type="string"/>
    </object>
</database>

PersonDatabase db("sqlite3", "database=person.db");Person person(db); // construct Person, does not write anything to database

person.name = "Bob"; // assign values to fields
person.age = 20;
person.update(); // writes a new record to database

person.age = 21; // Bob got just older
person.update(); // updates old record

person.id = 100; // force internal identifier (id) to 100 
person.update(); // updates old record
