Modeling Baseball Cards: A Case
Study
Robert K.
Hay & David C. Hay
Essential Strategies, Inc.
Abstract
Ok, when did you get exposed to data management for the
first time? Your first SQL course? The time you got dBase II on your first PC?
No, we contend that you became aware of data management
problems when you started collecting baseball cards. First, of course there were issues of storing
the physical inventory. Then, as you
looked at the cards, you began to understand the limitations of this medium in
truly representing each player's performance.
You saw, for example, that one card per player was ok, but sometimes
players changed teams in a season, and that required two cards. And what happened when they started
collecting new statistics?
It turns out that modeling the data on baseball cards is an
excellent exercise of data modeling skills.
This presentation will describe the development of a data model as
the modeler achieves successive insights
into the subtleties of the underlying data.
Beginning with a simple model of baseball cards themselves, the model
will be extended in stages, until it becomes one that can serve as the basis
for a true database to capture each player's performance throughout his career.
This will be an example of the way to develop a data model.
Audience
Beginner, intermediate

Dear members,
If you read this message prior to September 7th, I
will still be in France at the time, or on my way back. I know you will
have an excellent meeting, and I wish I could be with you to listen to David Hay
on a great topic.
Related to the drawing I gave you last month (see
below for quick reference and see the August Newletter for a complete
introduction), I would like to explain a little bit what
it holds. Let's look at the "Data/Information" box for a moment. There
is an "about" arrow coming from it, and going back to
it: this implies a recursive "about". So, from "Data/Information" we
arrive at "Data/Information about Data/Information", which is the
"Data/Information" called "Metadata/Meta-information" or data models.
Looping around a second time, we get
"Data/Information about Metadata/Meta-information", which is the "Data/Information" called
"Meta-metadata/Meta-meta-information" or data models about data model
repositories. Are we talking here about metadata models, or data
meta-models? As you loop a third time, you get into "data/information"
about a higher level of "data/information meta-structure". As you loop
a fourth time, it is your own brain that starts spinning out of control
into a headache. So, let's stop here with that arrow, for now.
Another box is called "Process/Procedure" and there are two "about" arrows
between this box and the "Data/Information" box. So we have
processes/procedures about data/information as well as data/information
about process/procedures. Remember that loop we went through? That
means these include also process/procedures about metadata/meta-information
and process/procedures about meta-metadata/meta-meta-information, and
so on, as well as metadata/meta-information about process/procedures and
meta-metadata/meta-meta-information about process/procedures, and so
on.
Oh, wait! There's more! (Don't you like those
infomercials?) There is also a recursive "about" arrow going from and to
the "Process/Procedure" box, which means... and combined with... OK.
I will stop here, for this month. But you can see where I am getting at with this diagram.
Now, did you see what we are planning for the
month of October? A regular half-day meeting plus a two day seminar. Who said we had to
wait for December to be super-active?
We are now half-way through our membership drive.
Renewal invoices have been sent, and thank those who have returned them with their dues
payment. If the name of your company has changed recently, we need to know what
the old name of the company was, in addition to the new name, so we can tie
your payment back to your historical records in our "database. Again, Paypal
is the payment method of choice. But if you can't use Paypal for whatever
reason, sending your check to our P.O. Box will work as well.
We now have four speakers planned for DAMAday. If things go as planned,
we may need to run two tracks in parallel during one half of the day.
When was the last time we had more than one track going during a DAMAday
event?
I'll see you in October.
