Re: A Growing Dislike for SQL-OOP Mappers

in reply to A Growing Dislike for SQL-OOP Mappers

All very good information. I'm glad we don't all agree here. That's means thought is going on. The one thing I've realized is that my gripe about current sql->oop practices in perl is that the current popular mappers assume the stance that the data access object is the same as my public object/interface. That may be true in some cases; not true or desirable in others....and both sides are OK.

Howdy! Interesting... I had to write a term paper on an "advanced Java server technology" for a Java programming course. I chose to look at Object-Relational Mapping, and focused on something called SimpleORM. Some ORMs try to make persistent objects indistinguishable from non-persistent objects, while others force you to directly acknowledge the difference in the code. SimpleORM did the latter (although you could then put a wrapper/facade around DAOs to hide that down the line. Now, one reason I liked SimpleORM was that it doesn't use XML anywhere, and doesn't try to hide the fact that some classes are different because they have a backing store for persistence. yours, Michael	[reply]
