Your IBM i HTTP Server powered by Apache is a powerful web-serving system akin to a bank staffed with multiple fast-working tellers. The AJAX requests coming in from your front-end apps are like customers entering the bank to perform transactions.

Nitro Query apps containing charts or graphs can make conveying your company’s business trends or performance metrics much more effective than showing raw numbers alone.
