What is a better name than Manager, Processor etc? [closed]

Answer 1

Take for instance name DataProcessor.

First it is true that each function works with data, takes data or return some data unless is

void f(void)

But if it is such type of function it absolutely makes something so it is Processor in any case.

DataProcessor is basically anything because it does no say what it manipulates and how. So you should replace

DataProcessor with UserInfoStore for instance.
