We don't need HiveMySQl, we have it, it is called HAF, here you have about it:
@mickiewicz/what-is-haf

I just don't have an idea, why we still need Microsoft SQL, if we have HAF, Hive account@arcange ?

And, no, you don't understand it, what i mean:

Quote As you see, the service is what we all are looking for and not the different parts the service is built with.

We are looking for free and open world here, and not just for service to work, all of these DB works great, and are almost the same in speed, so there is no big difference. And devs can create with all of these DB dApp's, there is, again no big differences.

Like you can see, HAF is done this already.

And, don't get me wrong, we don't need closed source banks here(as a service), we built Hive and HBD as a decentralized service, and we need to build many other dApps (I agree, we just started, and there is much work to be done), to NOT need for banks, assurances, and so on.
So we fight here for this, for our free and open source world, and I don't promote the banks to save money to people, I promote Hive and HBD. The same is with DB underneath.
Like fiat, it works, but, how it works? People have ever bigger problems with it to live and to earn, in every corner of the world, just because the fact like you say, they don't care about the underneath "DB (banks)", they just continue to use it, blindly, without asking, hey what's wrong here, why i'm having trouble with fiat, how this fiat works, where are the problems... But we should don't care how the fiat works, we just should use it, in your opinion? Why then we are here, on Hive, beside making friends and collaborations, blogs and vlogs? I hope, you see now my point, it is not just about a service to work, it is about how is created and how it works.
