ORM(Object Relational Mapping) is a concept or technique which acts as a bridge between your programming language and your database. Object Relational Mapping helps to execute SQL queries without writing them explicitly. Once the ORM is configured in an application, the user can use the OOP concepts like classes and objects to interact with the database. ORM methods are one of its strong features which helps in executing SQL queries without writing them down explicitly. With the help of ORM methods, the user can implement the OOPS concepts to interact with the database. Odoo creates and manages tables for us inside the database. Thus reducing our work of creation of tables using the queries.
