What is a "Web Block" in OutSystems?

A "Web Block" in OutSystems serves as a reusable component that facilitates the creation of user interface elements and encapsulates related logic. This modular approach allows developers to build components that can be easily reused across different screens and applications, promoting consistency and reducing redundancy in development.

By encapsulating both UI and business logic, Web Blocks enable more maintainable and scalable applications. They can be created to include various UI elements such as buttons, input fields, and data display areas, along with any logic needed to handle user interactions, data processing, or connecting to other components. This makes it easier to manage changes and updates since you can modify a single Web Block without affecting the entire application.

In contrast, the other options refer to concepts that do not describe Web Blocks. While database connections, testing frameworks, and user permission management are essential aspects of application development, they do not relate to the specific function and purpose of Web Blocks in the OutSystems framework.
