What was your experience with db4o?
Really good :)
It was the second time, I used db4o and it was nice and easy. It integrates nicely with C# (at least the latest versions - previous were java-oriented only).
Queries are easy to create and use. Even though I didn’t use it for any public available stuff, it seems, that you can’t hit any typical string escaping problems when constructing them - that’s a plus.
Lazy object activation is also nice.
I just recommend playing around with examples - they show most basic stuff you can do.
Also once you ask about commercial licences, support / sales dept. gets VERY nice :)
