Drupal Architecture Diagram?

Hi guys,
Just wondering if there is a Drupal architecture diagram(s) - I think some nice diagrams would help understanding how everything fits together.
I'm thinking class diagram, rendering pipeline (sequence diagram?) ER diagram for the database etc.
Always good to keep a systems documentation up to date
cheers,

we don't have anything like that, as far as I know. Something as elegant as Drupal does deserve some pretty diagrams though. Hope someone is inspired to produce this.
Diagrams of Drupal
Here Here! Excellent thoughts. The diagrams are a real MUST have!
Uhm
(just stumbled in by random)
Isn't the diagram a help to create the database? Not the other way around?? Just skip the diagram guys! You should have had it before you made the database!
I beg to differ
It's always good to have documentation, even if it is written after the fact, instead of before.
As for an Entity-Relationship (ER) diagram of the database, it is definitely worth having even after the database is made. It makes the database easier to understand for someone new to working on Drupal. And if there is every any change to the database, it will be just as invaluable as having created it before the first database.
If you've got an ER tool, it's even better because you can reverse engineer the current database into an ER diagram, and then generate the database after making changes in the tool to the diagram.
Is the database relatively normalized (e.g. 3rd or 4th normal form) for most of the tables? If so, I've got Sybase's Power Designer here and can reverse engineer the database with a little help on getting the non-obvious relationships connected.
ER Reverse Engineering
Try downloading dbdesign from fabforce,com. It's GPL, windows app, and is a pretty good ER diagrammer designed for MySQL and can reverse engineer a database into a diagram very well. I tried it on the Drupal db and it worked fine.
ER Designer
It is fabforce,net
there is an ER diagram of the drupal database
made by slavica here
This would be sooo helpful.
Does anyone have a copy of the image posted above?
I found the old link on archive.com but the ERD PNG image isn't available:

Im looking for a simple diagram showing how the template system works together.
Its kind of comfusing because the tpl files use php variables like $content .
However other than hackinf through the css and php code there is no way to see how one tpl file fits and relates to another along with the CSS related elements.
Hi, It appears to be this

Jeff Eaton has some great
Jeff Eaton has some great diagrams on aspects of the Drupal system, primarily the FormAPI:
Development cycle - http://jeff.viapositiva.net/node/477
Drupal form processing - http://jeff.viapositiva.net/node/457 (see attached image)
FormAPI 3.0 - http://drupal.org/node/138706#comment-233445 and http://drupal.org/node/138706#comment-233448
Edit: wow, I didn't notice initially that this was such an ancient topic.
Guys, I'm looking for Drupal Architecture diagrams
Greetings,
I'm looking for Drupal Architecture diagrams for a document I'm putting together.
If there are none I'll draw em up and contribute them back.
Any new updates on this front.
Arman.
Yes please
I've just negotiated with the supplier of a Drupal-hosted site a regular export of the database for reporting purposes. I think i'm going to be wandering around in the dark without some clues on the db structure, so please do post any diagrams.
(This is Drupal 5 BTW, I assume 6 is significantly different?)
