Getting set points from database

I want to create a database where the operator can input set points. These set points include temperature set point, pH set point and process time. These set points will then be used by the Arduino as inputs. How do i achieve this

You want to know how to create a database? There are many excellent tutorials in the internet on how to create a database. May I recommend that you use MySQL, it's a bit easier to access from most MCU's, on this site.

Once you have created a dB you write code that loads onto the MCU (microcontroller unit), The code will reach out to the dB get the info and react accordingly once the user has been ID'd.

Creating a dB is beyond the scope of this website.

Do you really need a full featured database for this? It's plausible, but it seems like overkill unless you want to keep history.
