In the following example we have three database tables called 'entity', 'user' and 'group'.
Users and groups are both entities.
The only thing we have to do is write 3 classes (Entity, Group and User) and make iterative
setTableDefinition method calls.

<code type="php">
class Entity extends Doctrine_Record {
public function setTableDefinition() {
$this->hasColumn('name','string',30);
$this->hasColumn('username','string',20);
$this->hasColumn('password','string',16);
$this->hasColumn('created','integer',11);
}
}
class User extends Entity {
public function setTableDefinition() {
// the following method call is needed in
// one-table-one-class inheritance
parent::setTableDefinition();
}
}
class Group extends Entity {
public function setTableDefinition() {
// the following method call is needed in
// one-table-one-class inheritance
parent::setTableDefinition();
}
}
