Hello,
I would like an advise on the following problem :
I have a table of patients.
Each patient can make different biological assessments.
Each assessment is always decomposed into different laboratory tests.
A laboratory test is made of a test number and two values coming from analysers.
I used to program for a medical tester.
I used method 2:
2 - a table with 60 rows for one assessment :
results(#assessment_nr, labtest_nr, p, d) where p and d are my two
results.
The BIG advantage was changes to the tests, adding new ones, or deleting
fields. Made it much more flexible.
The schema is :
Patients(#patient_nr,name,etc...)
Assessment(#assessment_nr, #patient_nr, assessment_type, other usefull
values).
Assessment_types(assessment_type, labtest_nr)
An assessment is composed of different tests, let's say assessment type 1

You should not use the placename as a PRIMARY KEY, but it can still have

Read up on database normalization. (do a search on
your favorite search engine) It will give you an
appreciation of storing related pieces of info in
different tables. Though you shouldn't need a series
of forms to access the data (most of the time) - this
has more to do with your programming
It might also help to at least try to understand why you normalize. Don't
just try to follow the rules, there is some art to it as well.
