I am looking for WordPress chart/diagram system design.
I found only the template hierarchy diagram, but it's only part of the system.

Reset to default 14More than an Answer, this is a research and a compilation. Database Description already in Damien answer.
A Google search reveals this in WordPress forums:
UML documentation of WordPress
As far as I know, that's all we have. If you want to write one, I'm sure it'd be welcomed :)
(Ipstenu, referring to the Database Description)
UML of WordPress MU?
There will likely never be UML diagrams of WordPress because it's not an OO system. Some parts are OO-like, but overall it's whatever that particular code contributor made work. There's no map, just code.And IMO, the point of UML is that it's done in the architecting phase. A project like WordPress would be hard-pressed to have this since it's a fluid integration of independent developers contributing to the core.

I thought this Question was a duplicate of the following (but mods said it's not):
Where can I find a real architecture document on Wordpress?
In it, Mike Schinkel states:
These generally are not some the open-source WordPress community focuses on doing.
One answer points to an old article with this diagram:
And the other to this Wordpress 3.0 Program Flow (PDF)
Rarst answer to this Question ( When should you use WP_Query vs query_posts() vs get_posts()? ) has a nice overview of WP_Query:
Another from Rarst on core load:
And finally, a totally unrelated Question about performance ( Refactoring Wordpress to improve memory performance ), but with very nice graphs :)
If you are looking for the database schema, there is a version on the Codex:
