If the user’s handheld is maintaining a local database that replicates a portion of the enterprise database for each user, how much data can be maintained on the handheld?

The amount of data stored on the handheld is really only limited by the amount of memory on the device. The latest BlackBerrys have 64 megabytes of RAM, for example. From a practical perspective, the size of the local data store is limited by the processing speed on the device.

In our experience, 2 megabytes of data is the outer boundary for current devices. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
