Can i have any persist in a process in process pattern

i'm trying to use rule and process pattern in my project. in a article i find this :

A process is defined as a series of actions in which one or more inputs are used to produce one or more outputs.

now my question is :

can i have any persist in database in a process,in this case my output can be persist result ?or we should return some output then persist that output in other place.
