This is the entity relation diagram, first sketchy Draft.

• Node A simplified node object. Should not contain stuff like titles and/or hardcoded bodies, etc.
• Node types Describe each node, basically a JOIN table between fieldinstances and nodes_
• Node field instance the field as attached to a node type. So this is a specific field in a specific node.
• Field types. All fields sit in a library. CCK calls this widgets
• Field type form elements. A JOIN table linking a PHP-formAPI-form-type to the fieldtypes_

• Form elements is not a database table, it is a php-coded-array form ‘entity’!

• Display profiles. the V part in the MVC Example: user_field can be displayed as “link to user profile”, or “plain user name”, or “substr-ed username”. The display profiles handle this. this table describes what PHP handler should handle the display of the entry.

• Node characteristics. JOIN table to link the nodetype to the handler of that node. Currently exists in PHP only as hooknodeinfo()_

Note that this ERD is not describing database tables per-se. Some entities could even exist as PHP.

Disclaimer: I am clueless when it comes to ERD stuff, I don’t know the app to draw them well either. It is probably all wrong, and I probably use the wrong elements and diagram parts. But I hope the idea is somehow clear.
