Hello Larry,

LC> LC> Some of the questions I have are:

LC> Do I create a special class for every possible property type?
Create canonical class that will map all undefined to defined, for example using XSLT
LC> How/where and when do you translate between internal representation

in the class where u need to show your control
LC> If UI and database are my primary uses of the business object,

Well........properties of what? seems not, there are several cases where it may be numeric data, but
u can declare everything as string and then perform convert

use enums, where u can map Sunday to 1 and vice versa
