Usability – why inserting data takes too much time

Scalability, performance tips, and multithreading are the main tools we can use to tune machine performance. However, the effectiveness of the system you design depends on the overall performance of the whole processing pipeline, which includes both humans and machines.

As a software architect, you cannot improve the performance of humans, but you can improve the performance of man-machine interaction by designing an effective user interface (UI), that is, a UI that ensures fast interaction with humans, which, in turn, means the following:

• The UI must be easy to learn to reduce the time that is needed for the target users to learn how to operate it. This constraint is fundamental if UI changes are frequent, and for public websites that need to attract the greatest possible number of users.
• The UI must not cause any kind of slowdown in data insertion; data entry speed must be limited only by the user’...
