What is the main purpose of Screen Preparation?

The main purpose of Screen Preparation is to fetch data from databases. During the screen's preparation phase, the application retrieves the necessary data to be displayed on the screen. This ensures that all relevant information is available when the user interacts with the interface, allowing for a cohesive and informative user experience.

By populating the screen with the required data, this step is crucial in preparing the environment before it is rendered to the user. It involves gathering information, applying business logic, and preparing entities and records that need to be used within the screen's components.

While there are other tasks associated with the overall screen lifecycle, such as managing widget rendering, handling form submissions, or directing users, these activities occur at different stages or in response to user interactions rather than being the primary goal of Screen Preparation, which is fundamentally focused on data retrieval.
