NoSQL x OO Database's

[Sidon]

Hi,
I'm working in my "term paper" on a TI course. I choosed the NoSQL
subject with focus to the MongoDB. I would like show the advantages
and disvantages between nosql and OO databases.

There are materials about this issue? some clue?

Answer from a practical standpoint: OO databases (with more than
10 years of ZODB programming) and MongoDB are pretty similar.
MongoDB is about documents (and data without associated class
or schema) and can be turned into an OO-ish database e.g. using
an object-document mapper. A OO-database knows about the class
of course (as the term OO indidicates). An OO-database e.g. can store
hierarchical data compared to MongoDB where no implicit hierarchy
of data is given (except you implement something using parent pointers
etc.). "NoSQL" and "OO" databases are broad terms and difference may
vary on the concrete database you are trying to compare. Not sure
if an academical comparison of both concepts bring you any step further.
Comparisons of existing database from both worlds is likely
more helpful. In the end: everything is a database and YMMV.
