Oracle NoSQL database
I’m just reviewing Oracle NoSQL database. This database is part of BigData and Oracle has an interesting view about the coexistence of NoSQL, Hadoop, Traditional SQL.
Check out this image:

Oracle view is really impressive and may become a real challenge.
Oracle claims to have a BASE compliant database but this seems not true. Reading documentation you can discover that sometimes eventual consistency model is not obeyed.
I’m also impressed from this technical aspect: ACID compliant transactions. Is this the first NoSQL database ACID compliant? Is Oracle able to deal against a paradigm? Is it able to change the theory? Of course not.
Support for atomic transactions is not provided in fact and this is in contrast with A of ACID.
Ending, I can suggest the interesting overview offered by Daniel Abadi, available here. Furthermore you may also check this cool link too.
