What programming model does Liferay primarily use for the backend?

Liferay primarily utilizes the object-oriented programming model for its backend development. This approach focuses on the organization of code into reusable objects that encapsulate both data and functionality. In an object-oriented paradigm, the primary building blocks are objects, which represent real-world entities and their properties.

This programming model promotes better code organization, maintainability, and scalability, which are key for building complex enterprise applications like those developed with Liferay. By leveraging features such as inheritance, encapsulation, and polymorphism, Liferay allows developers to create customizable, modular components that can interact with one another seamlessly.

While other programming models such as event-driven and reactive programming have their advantages, they are not the primary paradigms employed in Liferay’s backend design. The reliance on object-oriented programming allows for a robust framework that maximizes the reuse and extension of code, making it a vital aspect of Liferay's architecture.
