Basic architecture and technical characteristics
Architecture
Odoo adopts a three-tier architecture design, including front-end user interface, back-end server and database layer. This design enables Odoo to easily adapt to various business scenarios and supports multi-platform deployment.
front end
Odoo's front-end is written in HTML5, CSS3 and JavaScript, providing an intuitive and easy-to-use user interface. Users can access the application directly through the browser without installing any client software.
rear end
The backend consists of multiple Python scripts, which are responsible for processing requests sent by the frontend, executing business logic, and interacting with the database. The backend also contains a workflow engine for automating workflows.
database
Odoo can use a variety of databases as data storage layers, including PostgreSQL, MySQL and SQLite. Among them, PostgreSQL is the officially recommended database option because it provides better performance and stability.
Technical characteristics

In addition, ORM also provides some advanced features such as transaction management and data validation.
