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...


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.

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


What do you mean ETL project??...

ETL - Extract, Transform, Load

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


Or moving data from external sources to databases.

It's pretty much like listed above. Moving data to or from usually (but not necessarily) disparate sources and targets is generally classified as ETL unless it's a "backup" (which, I suppose, could be classified as a form of ETL especially if used to move data from one system to another).

You could possibly extend ETL to include a backup or replication or mirroring or logshipping, but wouldn't that be more like EL and not ETL?
