my idea is to create at table with AttributeCategories, Attributes, AttributeValues and AttributeForm.

Attribute Category my have the information like 'Demographics', 'School Information', 'Contact Information', etc with its Own Unique ID.

Attribute may have values like AttributeCategoryID with AttributeName, Its Data type (varchar, int) and data length with its Own Unique ID.

Now you can add as many attributes under each Attribute Category.

AttributeForm may have its own Unique ID with Form Name.

The Attributes may be mapped with Each Form to get the values on the against the specific form. This can be done in another table, say FormAttribute.

Now AttributeValue Table may have ID from table FormAttribute. And Values can be saved in nvarchar format in AttributeValue table.

Each Attribute will have unique value against each Form.

You can save any information using above logic. Even Lists and other datatypes can also be included and implemented in this strategy. But it will be too complex to explain in here...

How about that...?

CREATE TABLE #MyHead....

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I'm afraid mine has no foreign key constraints. Helps with creativity and problem solving and spews out some hillarious "stream-of-consiousness" conversations. Well, at least I think they're hillarious, and that's what matters, right? 😛
