It really just depends on how you're accessing the data. I tend to optimize for developer simplicity first, and then go in and adjust/split/modify code as needed when performance isn't where it needs to be for whatever application I'm working with.
The case where multiple models might work a little better than fewer, larger models is where you find yourself with either a lot of sparse data (some significant portion of the model being null or empty), or the need to consistently edit just a small portion of the data (one bit of metadata gets updated a lot, the rest of the information doesn't). But practically, I'd recommend building your app so that it makes the most sense to you, and then seeing how the performance rolls out. Worrying about "that might make the performance bad" from the very beginning isn't usually a good idea. -joe On 12/14/06, Austin Govella <[EMAIL PROTECTED]> wrote: > > > I'm new to Django, so I was looking for some advice on good model and > app design and on how that affects performance. > > My first app has nine models, and after working with it for a bit, it > seems like it's actually two apps: one for meta data and another for > content management. > > Are there any rules of thumb for when you should separate out some > functionality into its own app?
