What does the Update function handle in Qlik Sense?

The Update function in Qlik Sense is specifically designed to manage updates made to existing data records. It allows for the modification of records in the data model during the scripting phase. This is particularly important when dealing with data that can change over time, such as sales records, customer information, or inventory levels. By using the Update function, data architects can ensure that their data model reflects the most current information available, which is critical for accurate reporting and analysis.

The function facilitates the retrieval and merging of new data with existing records, ensuring that updates are applied effectively while maintaining the integrity of the existing dataset. This capability is essential for maintaining up-to-date analytics and insights derived from the data.

In contrast, change management in data sources refers to the general process of managing changes in data systems, which is not specifically what the Update function handles. Data load scripting focuses on the processes involved in loading data into Qlik Sense rather than updating existing records. Lastly, the visualization of updated data pertains to how data is represented in the Qlik Sense application but does not relate to the functionality of updating data records themselves.
