Quick question: Is there a way to let a user write (/create) documents and let him update and read his own documents, but not read documents of other users in a shared database?

No, fine grained security is done as design documents for updates and not for reading. You can:
use database-per-user and replicate them to the shared database.
have the user only add to their own _users document as _users implements this special case.

I have multiple JSON and XML(100s of different formats as well) from Different Databases. Is there any simple way to parse and store the JSON into a structured format in my Datawarehouse.
Thought of writing Python or Java Program for each JSON/XML.But it will be very consuming. Looking for alternate simple options

Is there any way to store the data without using the database?
Not really no. You could use the localStorage/SessionStorage or IndexedDB for example. But all of these things can be cleared by the user.
Also when he is using an incognito session, the data will also be wiped when he closes the browser.

In the context of RESTful APIs, what is an example of a real world object, that would make sense to Create but not Lookup? Is there one?
--Edit--
The question was to ask if there exists a usecase where a Create API would make sense, but not necessarily a Lookup API for the object - in places where you wouldn't want to expose the data(using the lookup API) to the outside world.
How about a keystroke logger...sending POSTs to create the audit trail.
You would not want to allow anyone to GET the results (besides you).

I have a bunch of articles, on which I want to do word frequency and trend analysis.
The articles are tagged with date, author, theme and subject. I want to use these tags to slice the data so that I can get the most common words used for a specific author (or group of authors), theme(s) or subject(s). Overall and over time (trend).
How would I design this database (relational or other) or should I create a data cube?
Rizzoma.com made this with couchDB (noSQL) and Sphinx (fulltext search engine).
You can try to make it in another way, if you want, or test existing solution and repeat it.

At my work place they use qdb to store data. Can someone tell me in more detail "why qdb?" and can you refer me to some link so that I can read more about it? because everytime i search for qdb i find GDB pages
Why not ask people at work who actually use it? :)
Third link on google explains what it is:
QDB database
QDB is a user-contributed database that can read and write DBASE files.
