Description:
In Odoo 16, an abstract model refers to a special type of model that serves as a template or base for other models to inherit from. It is not meant to be instantiated or used directly as a standalone model, but rather as a building block for creating new models with shared attributes and behaviour. An abstract model in Odoo 16 allows you to define common fields, methods, and other properties that can be reused across multiple models in your Odoo application.
