Data adapters, connections, and datasets

[Dave Cullen]

Can someone please explain the relationship between data adapters,
connections, and datasets?

Why would an application have one adapter and multiple data connection
objects? Does each form that uses data need its own connection?

Have a look @ this group for language unrelated questions:
microsoft.public.dotnet.framework.adonet

Dave,

Normally an application has one dataconnection (or it should use more
databases) and can have more dataadapters.

I find this page a perfect introduction to the dataadapter.

For more questions about this I would in your case follow Armins advice to
ask for more in the newsgroup ADONET because this is not real a language
question.

I hope this helps,

Cor
