mostly avoid using numeric keys however in this case, they will save you a
world of headaches.
My suggestion to you: Create one table per taxonomic level, starting at
Kingdom and working all of the way down to
I'm working on a big animals database and have a
question that's a little hard to explain, though I
suspect it will make sense to the pros.
First, a little background. I'm tentatively setting up
a parent-child relationship and putting all the basic
mammal data in a separate table. Below are some

Hi All,
Can MySQL give some indication of how many questions are being asked to each
database?
Using the show variables, I can get the total questions, but was wondering
if it's possible to get
it broken down on a per database view?

mails.
From the mails I get the idea that you have quite some experience with mysql.
We are planning to migrate our database (currently oracle) to mysql.

1. Is it a good idea to have all the columns in one big table ?
This will depend on the nature of your data. You say you have many varchar
columns. If many of them contains the same value, you could get substantial
speed/space improvements by splitting (normalizing) the

Yes, but is there really a big difference as long as the data is

Yes, either on a separate physical machine or a different HDD (to curtail
costs, I'd first go for HDD).

Roger, assuming the database space as allocated is used up and I
do not want to remove the data, but I have lots more space to
allocate, is there a way to extend allocated space in flight?
Or, does MySQL automatically (and inflight) extend beyond
