Re: Multi-tier programming on devices

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Pushing it to a single tier would likely gain nothing in memory usage. It's
also not true that you have a 32MB hard limit. The CF does a lot of
allocation from shared space. You have a 32MB virtual space limit per
process.

Howdy all,

Is it advisable to write Mobile Device applications using multi-tier
methodology? Or as Devices are much more resource-limited, would keeping
the number of tiers help reduce memory and processor usage?

I know apps on Devices can only use a maximum of 32MB of RAM, and
unfortunately our app is approaching, and at a push can be made to breach
that 32MB barrier. It's written in VB.NET, and has 4 tiers:-

1. GUI
2. Business logic
3. SqlCe interface
4. SqlServer interface

If we squished the number of layers from 4 down to 2 (GUI & "Everything
else"), would this help things memory-wise?
