Re: Generic Package

I discovered a possble design mistake in the program I wrote for my
Master's course this semester.  It's working and all that but I think
I could have saved myself many hours of work had I recognized (and
regurgitated from my undergraduate knowledge in 2002) the "is a"
concept.  With respect to databases a tuple "is a" collection of
attributes and a table "is a" collection of tuples and a schema "is a"
collection of tables.  I could have used a generic "collection" to
satisfy tuple, table and schema and I wouldn't have had to write code
to iterate, add, delete, etcetera from them.

Does that help explain it?

I think the Booch components may have something I'm looking for.  Even
though this site http://www.adapower.net/booch/overview.html says it
would be better to use a "collection" (there's the word again) than a
linked list I think I could have used the generic linked list for my
purposes.  I wish the site had given more information as to what a
"collection" is and where to find more information about it.  Then
again, I didn't read the whole thing.

So what would be best to choose?
