Remarks
Odoo and ORM: Odoo uses ORM(Object Relational Mapping) technique to interact with database. ORM will help to create a virtual object database that can be used within from the Python. In ORM technique each model is represented by a class that subclasses Models.model.
Models.model is the main super class for regular database persisted Odoo models. Odoo models are created by inheriting from this class.
Example:
class Employee(Models.model):
_name = 'module.employee'
#Rest of the code goes here
Here _name is a structural attribute, which tells the system about the name of the database table to be created.
Each model has a number of class variables, each of which represents a database field in the model. Each field is represented by an instance of a openerp.fields.Field class. Fields in Odoo are listed below..
