Are validations performed automatically in OutSystems?

In OutSystems, validations are indeed performed automatically as part of the framework's functionality. When you use the built-in data types and validations in entities and structures, the platform provides automatic validations based on constraints set in the data model. For example, if a field is marked as required or has specific data types, the framework checks inputs according to these rules automatically when interacting with the UI.

Moreover, OutSystems also offers features like validation feedback that can be configured to guide users in real-time as they fill forms, making user experience smoother and reducing the chances of invalid data submission. This automatic validation process helps to ensure data integrity without requiring extensive manual coding for basic validation scenarios.

The context around this question highlights that while certain types of validations can be specifically implemented on the client-side or server-side, the fundamental validations from the platform itself cater automatically to enhance both security and ease of use within applications developed on the platform.
