Update direct-db-connection.md

I see what you're saying. Is this better? I reworded slightly and swapped a few others around.

If this isn't better, I'm happy to change again.

 ## Functions usage with Direct DB Connection
 
-There's only one function affecting backend. This function is `consolidateBy`. It changes what data comes from 
-the backend. Other functions still work on the client side and transform data come from the backend. So you should
-clearly understand that you work with pre-aggregated data (by AVG, MAX, MIN, etc). For example, you want to group 
-values by 1 hour interval and `max` function. But if you just apply `groupBy(10m, max)` function, result will be wrong,
-because you transform data aggregated by default `AVG` function. You should use `consolidateBy(max)` coupled with
-`groupBy(10m, max)` in order to get precise result.
