Relations in a three-thier app.

[Anibal]

Hi,
I'm trying to learn about the three-thier layout, and becouse the DataSets
don't retrive relations from the data base,
i want to know in wich of the thiers i have to put code to make the
DataRelations objects between the tables
to include them into a DataSet.

Thank you very much.

Hi,

If you ask me, you should put the relations in at design time...

Strongly typed datasets - design time.
Non strongly typed - in your data layer.

Thanks for the answers, and forgive my ignorance, but what is a Strongly
Typed DataSet, where can i find information about that.

A strongly typed dataset is a dataset that inherits from a dataset.

Every property in a dataset is a string by default. You can specify the
structure of data that your dataset might hold via XSD at design time - and
xsd.exe will generate vb.net or c# code for you that lets you represent that
data in a strongly typed - dereferences manner.

Google for "Strongly Typed Dataset" - there is TONNES of information on
that - or pick any ado.net book.
