Why should distinct attributes be flagged with a value of '1' in Qlik scripting?

In Qlik scripting, flagging distinct attributes with a value of '1' serves to enhance performance. This technique allows the data model to more efficiently manage and process unique values, particularly when large datasets are involved. By representing distinct attributes in this manner, it reduces the overall complexity of the data model, leading to faster calculations and quicker query responses.

Enhancing performance is crucial in data visualization tools like Qlik Sense because it allows for real-time data interaction, minimizing the load times and improving user experience when exploring data visualizations. Instead of processing complete records for calculations, marking distinct values with a flag can lead to using aggregated data more effectively, optimizing resource utilization and speeding up the analysis.

While the other options relate to important aspects of data management, they do not specifically address the primary benefit of this particular practice in Qlik scripting, which is to enhance performance.
