How big is a big model

[thomaskilian]

terrabytes

no doubt. the appropriate measure. Or maybe Sunbites (sic!) would would be better?

[Paolo F Cantoni]

Using JET, no doubt.

Thomas,

Don't knock JET - the biggest Access DB in the world is surprisingly big...  I can't recall the details but it was impressive!

[Thomas Mercer-Hursh]

Merely big is easy.  Performance, stability, integrity ... count for a lot.

JET 4.0 has a 2GB limit. That is per .mdb file, but you can link files to exceed that limit.

Now I'm working on getting up the "position and velocity" database.....

I'll be back a bit later.

You're working too hard on this bruce,

Just get them all stored in your database. Now you can answer the questions easily for any given electron:

Position = here.
Velocity = 0.

You'll need some kind of identifier though, so users can specify the electron they want the above answers for. Perhaps something along the lines of a new UUEID (Universally Unique Electron IDentifier).

[Of course now you run the risk of confusion with really big EA models, where the new schema will have to accommodate a UUEID (Universally Unique Element IDentifier) field. Perhaps for UML we will have to accept something that's just globally unique - the GUEID - along with the corollary that our designs will only work on Earth, while the rest of the universe is on its own.]

[So there you have it. A big model should be able to accommodate everything on Earth correctly, but is likely to be weak at handling the entire universe. But once bruce gets the universe into his database, we don't really need to store it in EA.]

[Problem solved!]
