Too fast... regarding the class definitions, to achieve readability
here as well I would then suggest using a 3 letter abbreviation.<br>
<br>
...main classes:<br>
<br>
Power PWR<br>
Engine ENG<br>
Transmission TRX<br>
Chassis CHS<br>
Body BDY<br>
Electrics ELC<br>
<br>
...auxiliary classes?<br>
<br>
Safety SAF (Chassis, Body, Electrics)<br>
Security SEC (Power?, Body, Electrics)<br>
Comfort CMF (Chassis, Body, Electrics)<br>
Entertainment ENT (Body, Electrics)<br>
Communication COM (Body, Electrics)<br>
<br>
<br>
Also I would prefer "-" as a separator over ".".<br>
<br>
For my current application (battery pack + cell data), that would
result in type codes...<br>
<br>
RT-PWR-BattPack<br>
RT-PWR-BattCell<br>
<br>
...or general form<br>
<br>
*-PWR-BattPack<br>
*-PWR-BattCell<br>
<br>
Btw: general purpose codes could be written without "*-" prefix as
well? That would be...<br>
<br>
PWR-BattPack<br>
PWR-BattCell<br>
<br>

Silly me just assumed you'd prefer integer... I'm using text codes
in my own DB designs whenever possible due to readability.<br>
<br>
In other words: of course! :-)<br>
<br>
I'll modify my code now accordingly.<br>

<div>How about we just make it a text string, rather than
integer. Much clearer to read, and almost no impact on size.</div>

For general purpose type codes, maybe some classification
scheme would make sense? Maybe adopt some standard scheme
already defined for automotive data? ...if there is one...<br>

It seems there is none suitable, so here's my attempt at
defining one. Please comment.<br>
