> However, as you speak to more senior .Net developers, you will see them relying very heavily on code- generated data access layers or O/RM tools depending on the preference of the given developer.

I spent 2 months building an ORM in c# because my bosses let me. (Someone with more experience in ORMs than I had would have said “that doesn’t make sense, we can buy one much better for much cheaper”. And they would’ve been right. )

I’ve never used java’s ORM – I happened to start down the DOS and gwbasic, quickbasic, vb, c# route and am still there, so I use c#. I’m sure I’d love java and its surrounding tools were I to switch.

BTW – just my opinion, but I hate Datasets. Or, to be more specific, I hate the way I see some people use them. If I see a Dataset being passed from the data layer to the UI layer and back, I kind of shutter, and then I try to figure out who to shot over it. Datasets should only be used by one object to construct an instance of another object. And even that usage is unnecessary and in bad taste, IMHO.

There are lots of great O/RM tools available to the .Net community: just none from Microsoft. Since most new developers only know the Microsoft tools and have seen the Microsoft demos, they assume that is the way to develop apps. However, as you speak to more senior .Net developers, you will see them relying very heavily on code-generated data access layers or O/RM tools depending on the preference of the given developer.

As far as I know, many .NET developers use the DataSet. The DataSet object represents a cache of data, with database-like structures such as tables, columns, relationships, and constraints and it is always disconnected from the datasource. It is certainly not an ORM tool.
So you’d still have to write your own sql statements to populate it and does not provide any database paging functionality like ADF-BC does.

I’d really like to see both sets of code, partciularly the .Net example as it’s an issue we are grappling with at present. Any chance of getting hold of it? Links, etc?

Thanks

I gues the .net students didn’t use an orm framework because they are taught .net using the default tools in visual studio. I’m not familiar enough with visual studio, but i assume that by default visual studio doesn’t come with an orm framework.

That’s a nice result I wonder why the .NET people didn’t use a ORM framework, of course there are some availible for .NET too. Also I wonder how much experience the students have with .NET. Anyway it seems that the learningcurve for being productive with Java/Jdev/ADF is lower than I expected.
