What I miss in this whole story is the theoretical approach to the problem. I find it a little (just a little) dissapointing it is explained in technical terms, which is completely unnecessary.

O/R mapping is the key technique to use if you want to work with single entity instances, and set of entity instances, but always the entity is the core building block.

Datasets are the key technique to use if you want to use relational model sets of data, i.e.: the set is the core building block.

It's just set theory applied in different forms onto a fixed (DDL defined) schema.

Relational client side caches of unmaterialized objects, as you describe them, are useless, IMHO. You would still need to flush the state to the database before doing the query that does the projection. I like a projection to return arrays of objects as you have already mentioned. An ObjectView class can wrap the collection and provide the databinding support. Having said all that, I do use DataSets currently to reshape my domain model to the presentation model, but this is only because the tools are not currently here yet to databind to a domain model in a sophisticated way .I would much prefer to have an updatable projection.

you should humber your self, learn, then, learn again, and learn again. Be honest. Do not pretend you know. -- Learn CSLA (Rocky's framework), learn NHibernet. Use them to create some real applications. Better, learn Java. Java does not have dataset, so, it will give you some idea how things work in a real world enterprise level system. ---- You are suppose to know those things when you post; not some "theories", an undergraduate knows those stupid theries. Do not wast everybody's time!!!!!!!!!!!!!!!!!!!!

Scott is an old friend from the ObjectSpaces days, so I think he is partially kidding. And I can’t say I totally disagree with him WRT the typed DataSet because I think it has been shown that O/R solutions can do better then code generation. But that is a different topic for a different time.
-------thanks for providing the link; however, I'm puzzled, why you do not learn from him?????

DataSets vs. Collections

Mainz — Fri, 04 Jan 2008 05:57:11 GMT

Both DataSets and custom classes don't limit what you can do in any way, and both can be used to accomplish the same aims. That said, DataSets are fantastic tools for prototyping applications and represent excellent solutions for building systems in a
