I'm in the process of developing a few page layouts. I can map certain TextEditor's and RichHTMLEditor's fairly simply - and the concept of the data found in these controls being saved to a field is equally as simple.
But I don't understand where the data from a, potentially, arbitrary amount of wysiwyg editors (for example) being added to a web part zoned is held? Is the answer as simple as 'in the content database' and therefore something developers do not need to concern themselves with?
