Hi all,
I'd appreciate it if you could help me out with something.
I am trying to build a way to use faceted browsing through a database
of biological samples.
what I want to model is this:
Sample 1
race = white
age = adult
gene = XCFR2
disease = cancer
Sample 2
race = white
age = child
gene = 343GS
disease = stroke
date = 2010
country = Netherlands
So each sample could contain many tags. And each tag should have one
value at a time. A tag is a category (like race, age, gene, disease),
and a value is for lack of a better word, the choice or free text that
is entered to the right of the ='s sign. TAG = race, then value =
white
So does each sample have a many to many relationship with tags? And
then tags have a many to many relationship with values?
Each sample can have many tags (race, age, gene, disease, ...etc).
Each tag can have many diff values (race could be white, black,
hispanic, asian, etc...) BUT only one at a time
Each value should be mapped to one tag at a time. But I guess a value
could be reused, like the value XCFR2 could be a valid in gene = XCFR2
and discovered_information = XCFR2.
I think I'm making it too hard, but if someone can help, I would be
happy
