Question

I am trying to move the logic to the very high-level from the db. Technically, I am looking for extremely lazy-evaluation of things. I feel some non-sql -db is for this purpose because it looks like the computation is expensive in non-sql db and hence tend to be moved to the userspace. So

"by which NonSQL db I can initialize the DB -object in the
user-space probably in things such as JavaScript/jQuery?"

TRIALS

Trial 0: MongoDB, not possible according to this here.

Trial 1: CouchDB, open.

jQcouch may work, more here,
but cannot find the source code. So how can I initialize the couchDB
object to do something simple as db.test.save('hello world') in the
Browser console?

Answer 1

The code jquery.couch.js of Futon is well-documented here. You can see source code after installation of CouchDB for example with Ubuntu just $ sudo apt-get install couchdb:

"http://127.0.0.1:5984/_utils/script/jquery.couch.js".
