Subject Re: Kundera 2.2 released
Date Thu, 08 Nov 2012 18:56:41 GMT
Hi,

Thanks for info. This is interesting. But, I have a basic question: How can
Kundera benefit NoSQL programmer? Or, why can kundera benefit a NoSQL
programming project? I feel it is difficult to group different NoSQL
technique under one umbellrea as there are too much difference among NoSQL
databases in terms of db design, target problem etc. Also, my understand of
JPA is that it is mainly a OR mapping technique?

Thanks and regards,

Yiyu
