I'm confused here. Please excuse me if these questions seem silly.
What does "Property sheets created on ZClasses" mean, exactly?
If I use some DataSkin-derived ZClass instances inside a Customizer
folder, and if I want to store the data in the ZODB, do the
propertysheets for one of these ZClass instances come from
PersistentAttributeProviders or PersistentSheetProviders?
What is the difference between a Common Instance Propertysheet and a
Dataskin Attribute Propertysheet when added to a Dataskin-derived
Is the following true, part true, false, or irrelevant?
If I want to add a propertysheet that contains information from an SQL
database query to a ZClass-dataskin instance, I have to :
* Declare in my Product that the ZClass has that propertysheet (unless I
do clever stuff with triggers to add the sheet if it isn't there
* Use a custom SQL SheetProvider? Or an AttributeProvider? Or some
skinscript that calls various methods in my specialist?
