Traditional inheritance using _inherit performs in-place modification to extend the model's features.
However, there are cases where, rather than modifying an existing model, we want to create a new model based on an existing one to use the features it already has. This is done with Odoo's delegation inheritance, which uses the _inherits model attribute (note the additional s).
Traditional inheritance is quite different from the concept in object-oriented programming. Delegation inheritance, in turn, is similar, in that a new model can be created to include the features from a parent model. It also supports polymorphic inheritance, where we inherit from two or more other models.
