Default Application Architecture

Hello All,
We are going to migrate our asp web project( an ERP project) to asp.net. It is a huge application(containing about 1000 pages). So we have to desing an architecture. But the problem is our team does't have experience in designing nested project. Our project is made up of several nested project as you can imagine an ERP.
for ex.
Main project
   -Sales project
   -Account project
   -MRP project
   -Payroll project

Can anyone suggest us how should we nest our project so that all the modules should be lossely coupled and we can share global resouces of main project such as themes, master pages ect among the nested project. And we can cross reference the assembly among them.
Thanks in Advance.

Brother, I will recomend u following structure(it might not impress u) but I m using in my ERP project:

1) Make shared datalayer(mean datalayer disgin should be general and it should be one for whole project).

2) Make buisnesslayer for each different module and its components. This will be specific to module and its components and will access shared datalayer.

3) Make one master page, put menues on it for whole application & etc. Add other modules projects to here and build them in combined fashion.

I hope it is most simple and commenly used approch in developing multierd big probjects.

For objects common amongst the business, the business "rules" are likely also common across the business. Because of that you should consider developing a set of common business objects that would be shared among all modules. For specific differences, each module could subclass a common object as needed and override the specific methods and properties that need different implementations.

That sounds like a huge project and it's a really good thing you are taking the time to consider some design issues first!
