DataSet and TableAdapter really catch my eye. These classes map data relationship as an independent unit (e.g. disconnected from data source).
In a sense, it takes away work from ORM. I don’t have to create classes to map exact relationship. Sure, I also lose control over class design. The time saved is worthwhile.
I reread ADO.NET architecture again. I’m pleased they add new concept without altering old concept drastically. Many classes still have the same intend as in ADO.
These are new classes that’re not found in ADO.
DataSet – a disconnected entity, and may have mulitple sources. But why this is created in the first place?
TableAdapter, DataAdapter – these classes have no equivalent in ADO.
