SteemSQL is a publicly available Microsoft SQL database containing all the Steem blockchain data.
Data are structured and easily accessible from any application able to connect to a MS-SQL Server database. It allows you to easily access data contained in the Steem blockchain and perform analysis or find valuable information.
Browsing the blockchain over and over to retrieve and compute values is time and resource consuming.
Instead of having a local copy of the blockchain or downloading the whole data from some external public node to process it, you will send your query to SteemSQL server and get the requested information.
SteemSQL makes it possible to produce quick answers to complex questions.
SteemSQL works with a monthly or daily subscription model.
You will find more information about the subscription process here.
Two types of subscriptions are available:
