What is a Portlet in Liferay?

A Portlet in Liferay is fundamentally a web component that facilitates user interaction within a portal environment. It operates within the portal framework and is designed to generate dynamic content that is presented to users. Portlets encapsulate the functionality and presentation of different types of applications, allowing different applications to coexist on the same page while maintaining their behavior and state independently.

These components can respond to user inputs, such as clicks or form submissions, and can interact with other portlets, either by sharing information or responding to events. This model provides a robust framework for creating modular and reusable web applications, enhancing the user experience through interactivity and personalization within the portal.

The other choices present functionalities that do not align with the primary definition of a portlet. While creating databases, managing web assets, or handling user permissions are crucial aspects of a web application, they do not describe the specialized role of a portlet within the Liferay ecosystem.
