I'm playing around with db4o, and I have the Object Manager viewer thingy for Visual Studio. It seems okay, but not exactly on par with tools like HeidiSQL/SQL Studio/etc., not to mention that it locks the db4o file--I can't use my db4o app and Object Manager at the same time.
Maybe I'm using it wrong, but regardless, I'd like to know what else is out there. What tools would you recommend for looking at and manipulating db4o files?
UPDATE: I've been using LINQPad. There is some yak-shaving involved, but it's working pretty well. It still leaves a lot to be desired in terms of the functionality available in applications like HeidiSQL/SQL Studio/etc., but it's a start.
I suggest you use LINQPad as a first start.
Gamlor has a great tutorial on how to use LINQPad with db4o. You'll need to modify that a bit so you use client-server access (thus not locking your db).
I don't want to re-post his code here, because I think it's pointless and he's also a user here, don't wanna win his laurels.
For me, LINQPad seems to be the best approach, also because I can use it on my server, where I'd be having trouble with OME for obvious reasons.
We have discussed integrating some kind of "interactive LINQ query" into Object Manager (.Net of course :).
If you think this would be a nice feature, please vote in the issue here.
Also, any input on how to improve Object Manager is welcome.
Me too. I've been using DB4O for a few years, and have found the Object Manager clumsy, and often buggy (sometimes it won't open my large DB4O database at all).
I know of no alternatives, unfortunately.
