Why two types of models (form and active records) ?

What is the purpose of yii giving two types of models, one for form and other for active records which involves db actions?

CActiveRecord is a model related to a database table, it has the functions for manage a model (rules, activeLabels) and the functions for work with database (find, save, delete).

CFormModel is a model without database, it has only the first functions (rules, activeLabels)
