Hello all!

I'm a novice to CakePHP, have a rusty set of PHP skills, and am maybe
a 5/10 when it comes to MySQL & databases in general. I was recently
hired by a company wanting to bring their catalog design and web
development in-house. After digging through the existing site's raw
PHP code, I've decided to rebuild it from scratch with Cake. I'm blown
away by what Cake can do and how it does it! My last large-scale PHP/
MySQL project was during the php3-php4 transition when PHPLib was the
hottest thing around.

My company sells Widgets in the Medical field...lots of them...nearly
20,000. My largest task at hand is to build an app to both populate a
Widgets database and search the data. It's a little overwhelming and I
need some advice.

First, all Widgets have a unique Widget Number. All Widgets can be
divided into Top-Tier categories a couple different ways. For example,
a Widget could fall under Forceps or Scissors or Clamps, and could
also land under Cardiovascular and/or Neurospinal and/or Dental. A
Clamp will always be just a Clamp, but the same Clamp could be useful
in both Cardiovascular AND Neurospinal. So categorization presents a
challenge.

Additionally, all Widgets have a number of properties in common. They
all have a Price. They all have a Name. They all have Dimensions.
Here's the really tricky part that's making my brain hurt. They also
all have a number of properties that are unique either to the item OR
to the Widget's category. A Clamp may have a curvature with a specific
radius. A set of Forceps may have an angle. A Needle Holder may be
Straight or Curved, and may also have jaws that are either Stainless
Steel, Tungsten Carbide Coated, or Titanium with Tungsten Carbide
coating.

There are also relationships between certain items that I'd want to be
available for "Related Widgets" display on a Widget's page. For
example, a Titanium Needle Holder with Tungsten Carbide Coating may be
available in 6", 7", 8", 9" lengths, with jaws that are 1mm, 2mm, 3mm,
4mm wide and jaws that are Straight or Curved. I need to somehow be
able to make it clear in the database structure which Widgets are
related to other Widgets and how; keeping in mind refinable searches
(Show me all Titanium Curved-jaw Needle Holders).

Then there are things like Cases that hold predefined Sets of Widgets,
Widgets with X and Y dimensions vs. Widgets with X, Y and Z
dimensions.....and on and on and on.

Not only am I trying to figure out how to create this beast of a
relational database, I'm also trying to ensure from the beginning that
it's optimized for CakePHP and remains highly flexible for all the
unforeseen additions and changes down the road.

Brain.....very.....exploding. Please help!

A thousand thank-yous in advance to all who read and any who respond!
