What’s new

A few days ago, I announced the availability of the Witnesses table in the SteemSQL database.

The Witnesses table is a non-transactional table which contains a list of all witnesses and related information.

But what about having a full history about witnesses, how they moved in the ranking, when they missed block, how they published pricefeed, when and how long did they deactivated their witness node, ... ?

To be able to answer all those questions, I added the SSWitnesses table to SteemSQL. This table contains a daily snapshot of the most interesting values from the Witnesses table.

Each snapshot is taken every day at 23:59:59 UTC.

SSWitnesses table description

The table contains the following columns:

NameDescription

nameaccount name of the witness
votes_countnumber of votes the witness received
urlThe URL of the witness presentation post

SQL is a standard language for storing, manipulating and retrieving data in databases. And your work is well.

Just what I needed to see. Thanks for this update

Wow wow wow, nice post brilliant idea and so cool. Keep the good work flowing

I wanna know that why the don't use Mongo Database?

·

Because MS-SQL offers features not available with MongoDB

·
·

True but,
At present all big big company use MongoDB,
Exmp: Facebook

·
·
·

Facebook (And any other company worth their salt) uses MongoDB where it's a good fit, and Postgres/MySQL/OracleDB where they're a good fit.

·

Steemdata is a mongodb database, however, it's no-where near as flexible as a standard SQL database for this kind of thing.

This is fantastic.

Is there a way we could explain all of this in far more simpler language for lay men on Steemit?

I think the message would sink faster, deeper and longer that way.
