Thanks Philip, simple divide with great effect on my understanding and
thanks Steve for the links.

My Roadmap then:

1.For my Problem Domain objects, I create ZClasses (with Dataskin as base
class) with normal/dataskin? propertysheets

2.Then I delegate data management for my ZClasses to specialists:
  -  Create specialists for my Dataskins
  -  Select the ZClass under storage tab of relevant rack
  -  Add Skinscript methods which store and retrieve properties in RDBMS,
delete & insert objects into RDBMS.

Is this right?
