Re: Toplink vs OJB comparisions

[Robert r. Sanders]

So far I haven't done more than do a few test apps with OJB; although 
right now I am writing a simple intranet web-app that will make use of 
it.  After looking at some of the (now old) source code I have to say it 
is some of the cleanest and most well designed code I've seen in a long 
time.  One of the big advantages is, if you are willing to spend a 
little time, you can find out answers to questions you might have 
yourself.  As I understand it OJB provides several implementations of an 
Object cache, so you can configure it to best suite your needs (or if 
needed write, or have writen, a customized version).  While the 
documentation is a little "rough", frankly so is that of most commercial 
software products, and you do have this list of commited individuals, 
who in my experience answer questions quickly, and honestly.

Hi all,

I'm looking at Object / Relational products and see that TopLink
(http://www.webgain.com/products/toplink/ and
http://otn.oracle.com/products/ias/toplink/content.html) from Oracle is good
and also this product OJB appears good. The problem is, how can I make a
comparision between the two without getting into a lot of detail.
I'd like to know if there are any meaningful differences between these, for
example, I am aware that with Toplink, if you have say 10 threads getting
the same object 10 times it doesn't read the same object 10 times from the
DB and it also doesn't create 10 copies of the object in memory for each
thread, does OJB do the same? I could make up 100's of questions like these,
but really I want to get an idea from the people who use OJB - does it work
for a large distributed system.
What commercial systems are using OJB?
How can I convince my boss that OJB can be better than TopLink?

Thanks, Phil
