At the risk of sounding like a Big 5 consultant, "It
depends".
1) Strongly typed datasets rock, they are faster than
untyped, use intellisense... but your reason for
wanting to use them is important. I use them every day
of my life, but I also don't use them every day of my
life and there are reasons for both.
2) How much of your process is dependent on reads vs.

I've seen an Introduction on ADO.NET with its Datasets on .NET TV and Iam
now wondering how it is realized/used in real world applications.
I don't believe that one would create a dataset and add relations to it and
so on for every table in the application, this would be a real mess and this
has nothing to do with OOP.
Normally, would would create a class Customer, a class Invoices, Positions,
Articles and so on.
But how can this be...

Hello,
We have a robust (.NET 1.1 c# winforms) client-server application that
utilizes many typed DataSets, typed DataTables and typed DataRows. Our
application is a series of windows and popup windows where you can
edit information and data, nothing out of the ordinary. I estimate we
have something like 50 to 100 tables and/or views in our database each
of which map to one strongly typed DataTable. Now we have some odd 20
to 30 typed...

I have a class method that returns a DataAdapter. I want to access the
table(s) contained in the DataAdapter. Of course, accessing the DataSets
would be good enough, because I could get the tables from there. I can't
find a way to do this. Am I missing something?
Much obliged.

Hi,
I thought I had this sorted this morning but it is still a problem.
My application has a DataAccess Class.
When it starts, it:
Connects to a DB (OLE DB)
If it connects it uses an OleDbCommand with an SQL String and the connection
it has a DataAdapter with the command
then it fills the DataSet's DataTable with the streamed data.

I keep getting a concurrency exception the second time I make a change and
attempt to update a dataadapter. It appears this is by design, so there must
be something I can do to avoid it.
Example:
I have a dataadapter that contains one table with one row. I change the
value of the 'FisrtName' column in that row from Jack to John. I call
..update on the dataadapter it goes through fine. Now I change that same
column in that same row...

I've used datatables and datasets before. Datasets being able to hold
more than one table and datatables being only one table. My mind keeps
coming up with recordsets. I can't remember how they fit into the picture.
I'm going to be reading some records from a table in a sql db.

Hi all;
as posted some days ago, I'm converting an on-line app; I used to
heavily rely on strongly-typed DataSets directly dropped onto pages,
and so viewed by code(-behind) as well. In the next two weeks I
discovered that such objects are no more directly usable in pages,
namely in DataGrid which don't see them any more. Even if rebuilt in
Component Designer, and so visible in code, DataSets are invisible in
Page Designer, so now it's...

I'm trying to decide if it is better to use typed datasets or business
objects, so I would appreciate any thoughts from someone with more
experience.
When I use a business object to populate a gridview, for example, I loop
through a datareader, populating an array list with instances of a custom
class in the middle tier, and then send the array list up to the
presentation layer and bind the gridview to it.
If I use a typed dataset, I...
