Darn. I was hoping it was a diagramming tool ...

Aiee! Too much detail!
Actually, the outline you provide will probably be useful for your
lab-mates. However, it's hard for me to pick out the answers to the
questions I have:
1. Are "Fasta" and "Sequence" the same thing? (further questions assume
this to be the case).
2. We established in the last e-mail that there is potentially more than
one clone related to each clone_fasta and to each clone_qual record, and
that no clone has more than one fasta or qual record. Is that still
true?
3. In what order does the data arrive for your tables? I.e., is this an
accurate order of events:
(1) Clone data
(2) Sequence (Fasta?) data
(3) Qual data
(4) Contig data
(5) Library and Genebank data.
Is this accurate?
We can proceed from there.

That's what I'm asking you. The difficulty is that I really don't
understand what you're doing with sequences. Maybe you could get a
collegue to render an opinion?

We need to answer the relationship questions before we can arraive at a
correct table design.
