Guys,

Sorry. It's probably not a dev question... 

I'm writing a paper for my graduation (about Infinispan) as I said before. I'm having some doubts about what Infinispan really is. I watched some Manik presentations on internet and read a little articles. I saw Manik saying something like Infinispan be a in memory data base, and not just a distributed cache. And I read (http://java.dzone.com/articles/data-service-data-fabric) that Infinispan is something like Voldermort or Dynamo. And in some other sites, like http://nosql-database.org/, Infinispan is classified like a "Grid Database solution" (like Oracle Coherence) and somehow different of Voldermort. Reading Infinispan documentation and these and other articles, I not really sure what differs Infinispan and Voldermort.

I'm not really sure if I made myself clear, but I'm having some problems defining what is Infinispan (or what Infinispan wants to be in the end) (comparing with these other products).
