Development #55

Avoid running SQL queries inside a loop

SQL queries inside a loop seriously hinder performance, especially if the SQL server(s) are not on the local machine. That is because these servers are designed to handle several selections, insertions or modifications in one single query or transaction.
Wrongly used, these queries unnecessarily consume CPU power, RAM and bandwidth.

Design #111

Improve the process flow

The amount of time a user spends on a website or an online service is the most significant factor in reducing or increasing the website’s environmental footprint. In other words, the less time the user spends on the website or online service, the smaller the environmental footprint.
You must therefore try to minimize the number of screens, steps and unnecessary interactions while at the same time ensuring that screens are not overloaded and too complex, which in itself can be counter-productive.
