Whenever I think of this condition, I get confused. If my business is dependent user data, then how should I think of the design from scratch? What should I do to collect data from users or encourage them to use the website? I know what to do once I have enough data set but I have no idea with 0 users.
How did Facebook or Instagram get started with no users?
If there is no data available, display a big, centered text, saying something like Nothing here yet with a nice, attention-grabbing image (Preferably single color).
Below that, create a call to action. Something like Get started by adding new content or Get started by pressing the plus-icon below, etc. You can even integrate a button into this "Nothing here"-Message. It's a good guiding system.
Best color for this would be grey text color on a grey background. Google Drive is a very good example. It can't be mixed up with content and provides a clear CTA (Drop your files here or use the button "New").
For comparison: Thats what it looks like when the folder isn't empty:
Facebook is doing something similar. You maybe know the call to action they place next to their like-buttons: Be the first of your friends to like this. Or below videos or posts: Be the first to comment.
blank slates/ screens that don't yet have data. In a way to encourage user interaction. Might be useful. Check out signalvnoise.com/posts/… or signalvnoise.com/posts/…
