Hi folks...
As part of an assignment, I have to design and implement a fairly
small MYSQL 4.0.17 database for a fictitious travel agency. This
database will store data from customers submitting it through
application forms. I will test my implementation on an old Linux box
(RedHat 6.x with PHP 4.0.5 and MySQL 4.0.17, running on an AMD
processor and 64MB of memory).
Each APPLICATION form will have 4 parts:
- PASSENGER details: name, surname, etc.
- CONTACT details: phone number(s), postal and e-mail addresses
- INFORMATION on the trip: departure and return dates, etc.
- CONTROL data: agency-specific (e.g., booking operator)
If I put all the above information into 1 table, APPLICATION, it will
have around 30 fields and a record size in the order of 1 KB/customer
(no more than 10,000 records expected).
If I put the information into 4 tables (PASSENGER, CONTACT,
INFORMATION, CONTROL), then none will have more than 10 fields/record,
but I need to associate them with, say, the PASSENGER key. But, if I
use auto increment, I will have to rely on the mysql_insert_id ()
function, which I am not happy about, since multiple simultaneous
accesses of the database is in the specs of the assignment and this
function examines the last INSERT. (Table locks and transaction
processing might help here.)
So, my question is, which design path to follow: 1 table, or 4 tables
and, if the latter, how do I go about reliably retrieving the
auto_increment key?
Cheers,
Dimitris

Hiya Dimitris.
I'm gonna assume you are evaluated on database design and coding skills for
this project.
If that's the case.
Use four tables, at a minimum, and normalize your data as much as possible.
There are real world reasons to keep things un-normalized, but this is for
an assignment, and a grade, and my hope is that your teacher is using the CJ
Date book on Intro to SQL as the text.
If not - you should get it - its still avail for sale/purchase.
mondo regards [Bill]

what you need to have are opinions on the pros and cons of doing
things different ways, this way you can give reasoned arguments in
favour of a certain method, and reach a useful conclusion.
I have found that the things I learnt in an academic setting have
rarely been applied in real life.
This will of course be different for everyone which leads me back to
my first point.

Michael -
agreed -
but -
he's in an academic setting. Period. I teach as sql classes as well with
mySql utilizing the CJ Date Book.
He's not in real life [yet] so anything that will reduce his grade for the
assignment ? Who are we helping?
as to 'what you need to have are opinions ...' . Ah - I have many. Usually
paid for them, as well.
but that's another thing, and surely I digress.
If a project is for a grade in an academic setting, do it the way the
teacher wants it done. Period.
Anything else will be cause to 'take off points'.
But ? does it really matter ? Dimitris never posted back here asking further
questions.

Agreed, but it helps me pass the time of day, and who knows what
interesting people I will get to talk to !
....although to put this in context, I have just been on an Oracle
Designer training course and a lot of these issues came up with the
other group members.
Many hours of meetings then ensued over design issues.
I dont know how much Designer costs, but my conclusion was that
Designer is more of a burden. My experience mirrors this as I
previously survived without a design tool for 13 years. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
