From the context: Applets + Codd = "Coddlets".
He used Codd's name repeatedly, and the parallel to "applets" is obvious -- well, if you work in a company that markets portal plug-ins as "portlets", it is...
So it must mean little snippets, not of code functionality, but of data structure (in this case, TABLE! :-) definitions... Something like that.
HTH!

And "little snippets of data structures" make no sence to me

Me neither - but don't blame me; it's *his* concept! :-)

Virtual Structures
>> And "little snippets of data structures" make no sence to me <<
It is not snippets of data structures themselves, but snippets of specification of the relationships between the base components.
IOW, rather than "build the tree" in code like you do in stereotypic OOP, you *define a formula* for a tree. (Hypothetical only since it is the specific views that are defined, not physical structures, and so the label "tree" is not really appropriate.)
In p/r, one is less pressured to "model" up front, because it is assumed that the structures eventually used are *virtually* created as needed. You just have to make sure that enuf info is available in the "nodes" to be able to apply a structural formula to.

I understand all words
, but cannot make out what you're trying to say. May be an example?

how about this then
We could compare a p/r "role pattern" to an OOP one:

(I didn't show the OOP version. Jay posted a Java version once, but I don't remember where it is. Anybody volunteer one?)

Odd. Not a single mention of "coddlet" anywhere.

"A formula for a pattern or structure"

Still odd.
The only use of word "formula" on the whole page is here:
>>>>>>>>>>>>>>>>>>>>>>>>>>> You will note that many of my examples don't include a lot of code. This is because many of the GOF-influenced patterns are mere "viewpoints" in the relational world, created by a trivial relational or Boolean formula, and not a physical code structure. This makes them easier and less intrusive to test and change. Thus, to us table fans, GOF-like patterns appear Neanderthalic. It is better abstraction to use formulas to represent repeating patterns than to physically repeat them. For one, the same items can more easily participate in multiple patterns. Think about it. <<<<<<<<<<<<<<<<<<<<<<<<<<<
No matter how much I thnk about it, I don't get it. Do you mean using "WHERE" clause of a SELECT (or may be a view) instead of a list or a table holding needed elements? Fine technique, when you can employ it. But not really new or deserving its own term. Or did you mean something deeper?

Jay, where is your "Roles" link?
