I really-really wanted to see some numbers out of the Steem blockchain, and I found DBeaver, which is an open source database tool for data analysts and can connect to DBSteem.
I have found a Chinese tutorial with English translation about how to install, connect to DBSteem and set it up.
It took me 5 minutes or less.
The main part for SQL connection:
Host: sql.steemsql.com
Database/Schema: DBSteem
User name: steemit
Password: steemit
I wanted to see the top 20 users with the highest rep, their posts number and SBD balances.
I put this in
select top 20 name, cast(log10(reputation)*9 - 56 as decimal(4,2)) as reputation, post_count, SBD_balance
from Accounts
where reputation>0
order by reputation desc
