Anus MMO

I want to make an open world MMO but i have no clue how to piece things together.


I can easily make a simple multi-user tcp or udp server.
I can easily make use a database through a programming language.
I can do simple shit like update objects, AI, etc.

But how do i piece it all together?

Do i have 1 thread dedicated to updating the world as a whole? 1 thread dedicated to handling every single network connection, parsing input data and sending back output data retrieve through database queries if possible?

If you really want to have your own MMO without having to do much programming, you could just host a Stendhal server:

Or even if you don't like Stendhal and want to create your own MMO from scratch, you could at least look at Stendhal's source code for inspiration.
