How do Client Actions differ from Server Actions in OutSystems?

Client Actions in OutSystems are designed to run in the user's browser, which allows them to interact directly with the user interface and respond to user events such as clicks, inputs, or other interactions. This execution model enables a more dynamic and responsive user experience, as it allows immediate feedback and real-time updates without needing to involve the server for each action.

On the other hand, Server Actions are executed on the server side. They typically involve processing data, interacting with databases or external services, and performing more complex calculations. This separation of execution environments means that while Client Actions focus on user interactions, Server Actions handle data processing and logic that often require server resources.

Understanding this distinction is crucial for optimizing application performance and user experience in OutSystems development. Client Actions being executed in the browser allow for faster responsiveness to user inputs, while Server Actions manage the business logic and data operations, which are essential for maintaining data integrity and efficiency.
