 Column Importance: The importance setting helps define which columns are displayed on smaller screens. "Primary" ensures the column is always visible, "Secondary" is shown if there is enough space, and "Other" is hidden on smaller screens.

 Restaurant Name as Primary: Setting the restaurant name to primary ensures it is always visible, as it is crucial information for making a reservation.

 Image Column as Other: Setting the image column to "Other" hides it on small screens, which is acceptable as images are non-essential compared to textual information.

 Location and Reservation as Secondary: These columns are set to secondary, ensuring they are visible on medium to large screens but can be hidden on smaller screens if space is limited.

 Reference: Pega guidelines recommend using the importance settings to manage the visibility of columns in responsive layouts, ensuring critical information is prioritized (Pega Platform 8.7 Documentation, User Interface - Column Settings).

To configure a report definition that lists new customer cases created in a given day and the average opening balance for all account child cases for each customer, you should use the "class join" feature in Pega. This feature allows you to join data from different classes, which is essential when dealing with cases and their child cases. Specifically, you can create a join between the customer case class and the account child case class to aggregate the average opening balance.

To improve performance when fetching data from an external source in a cloud-deployed application, you should configure the data page to use a predefined key. This approach allows the data to be loaded once and then accessed quickly for subsequent requests.

Understanding Data Pages in Pega:Data pages in Pega are used to cache data, so it doesn't have to be retrieved from the source every time it is needed. Using a predefined key means that the data page is loaded with specific data that can be reused.

Configuring Data Pages with Predefined Keys:

Step 1: Define a data page and configure it to use a key for accessing data.

Step 2: Ensure the data page is set to load on demand or at a specific point in the process.

Step 3: Once the data is loaded with the predefined key, subsequent accesses to this data page will be faster because the data is already available in the cache.

Advantages of Using Predefined Keys:This approach reduces the need to repeatedly fetch data from the external source, thereby improving performance and reducing network latency issues in cloud environments.
