Normally you'd go a lot further into the design phase before considering physical implementations.

Your picture doesn't give a lot of detail and your question is just as vague. What do you define "right" as? What are you trying to accomplish?

If it's strictly an ETL project, maybe. Otherwise, probably not.

To me it looks like all of the arrows are going in the wrong direction.

You have a class that populates a dataset and that class also gets shipped off to a server.

It looks like there is nothing being done with the dataset.

With nothing being done by the dataset and the apparent misdirection of the arrows (assuming), I would say it looks completely wrong.

Then again, we have no real project requirements to make any determinations of right or wrong.

SQLRNNR...i think you are the only one who get it right...thanks for the advise my friend:-)

my classes contains a connectionString to a different server, because every server contains a different databases, so meaning in every classes i have different connectionString that will open the connection to a certain database....and mydataset contains all tables in a certain database...

Is this clear explaination? or should i elaborate more my friends(ladys and gentlemen) ?....

cheers 🙂

What do you mean ETL project??...

ETL - Extract, Transform, Load

Usually done when moving data from OLTP databases to DW databases.

Given this information, I think the graph is seriously wrong. Either each class leads to a server and a set of tables within that server's database, or you have 3 classes acting upon one database's information and then sending information to two other servers.

How well do you know the data? And what exactly are you trying to do here, because your explanation doesn't tell us what you're doing. It just tells us a very generalized layout.

And why do you need classes to point to a dataset anyway? You should be able to derive a dataset independently of the class. The class should only define what to do with that data once you have it.
