I have the following sentence.

The system must be scalable so it will remain effective when there is a significant increase in data and the number of users.

I don't know if it is grammatically correct; I used and between data which is uncountable, and "the number of users" which is countable.

Am I right? Is there any better situation that sentence will be?

1 Answer 1


There is nothing wrong with using and between an uncountable noun and a countable noun.

I need water and four eggs.

And just means the increase was noted for the data, and it was also noted for the number of users.

  • Yes, it is. I would rather write "there is a significant increase in data and number of users"; that is my style, though.
