Mh, IMO going into some details can't be avoided. Here is a starting point: http://c2.com/cgi/wiki?ObjectRelationalToolComparison Here is the management summary: 1. TopLink and OJB have a comparable featureset 2. TopLink has no ODMG support. TopLink has only limited JDO support. 3. OJB does not have a graphical mapping workbench yet. 3. TopLink is not for free. > 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? Yes, that's possible with OJB too. > 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. Yes. > What commercial systems are using OJB? We are running several commercial production systems for Europes largest retailer, KarstadtQuelle, based on OJB. > How can I convince my boss that OJB can be better than TopLink? I won't claim OJB is better than TopLink. But it has different price tag. cheers, Thomas > Thanks, Phil > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
