Which component is used to define business processes in Mendix applications?

Microflows are essential components in Mendix applications for defining business processes. They serve as the backbone for workflow logic, allowing developers to create a sequence of actions that the application can execute based on specific triggers or events. Through microflows, you can model complex business logic, handle user interactions, manage data transformations, and control the flow of the application.

For instance, when a user submits a form, a microflow can be triggered to process that input—validating data, querying or updating the database, and providing feedback. This capability makes microflows indispensable for orchestrating multi-step processes and ensuring that the application adheres to the defined business logic.

In contrast, widgets, domain models, and databases serve different purposes in Mendix applications. Widgets are user interface elements that allow you to present information and collect user input. Domain models define the structure of the data used in your application but do not dictate how business processes execute. Databases are storage solutions for persisting data but are not involved in the direct definition of business processes. Thus, while they are critical components of the application ecosystem, they are not responsible for outlining the business processes as microflows do.
