Hi,  I have been reading so much on Datasets and designing using layers, that
I am so confused I don't know what to do.

I am trying to build a Timesheet tracking application.  Most applications
seem to use n-tier design now, so I would like to try and implement this.

Anyway, I have a Data Access Layer in which I have generated typed datasets
using the designer.   I have created multiple datasets, with groupings of
tables that I think I will need to work with.

I then have a Business Layer which accesses these databases, roughly based
on what this series or articles talks about http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspnettut/html/aspnet_tutorial02_businesslogiclayer_vb.asp

I am a bit confused how to implement something fairly basic.

Say on Login, I need to verify the user against valid users (in tblUsers), I
also need to hold and frequently refer to the users access priviliges for
different screens, so i know what they should or shouldnt be able to see.

To check the user login, and store the details, should I have a business
object (User) to store I datatable?  even though all I really want is to get
one row?  ie the user who logged in?.  Or should I have the business object,
simply call the datalayer, return all the fields that I want and store them
in properties? (seems a waste, however storing a whole datatable seems a big
overhead).

I also need to be update the user with last logged in date and time etc.

I tried just using datarows, however, to check for an update I needed a
datatable...

I also need a maintennance screen for an admin person to add, update and
delete users and their priviliges.  SHould this be a seperate business object
that returns a datatable to the presentation layer.?

Any direction appreciated.

thanks

Take a look at LLBLGen  - it generates data objects which are much easier
to use (and more applicable) than the standard typed Datasets + datatables.

Any other advice that doesnt involve using a 3rd party app?
