[Haskell-cafe] Web Framework to Show Experimental Data

[Dmitri O.Kondratiev]

Hi!
I am looking for the Haskell libraries to quickly create some Web Framework
to Show Experimental Data.
Please share your experience and ideas. What tools would you chose for such
a framework:

== Architecture
There are several unsynchronized processes:
1) Finder - demon that periodically searches and collects JSON data from the
Web and stores this data in some sort of Archive (DB).
2) Processor - demon that periodically process new data from Archive
collected by Finder and stores results of its work in the same Archive.
3) Web application that shows processed data in a browser.

== General Requirements
*** Main requirement - simplicity and high speed of development ***
- Max Data storage capacity - 10 Mb
- Max number of Web users - 50
- Web UI shows what Archive has at the moment of user request.

== Web UI Requirements
- Multi-page view of long data sets (some sort of scrolling)
- Simple graphs and charts (desirable)

== Questions
1) What to use for the Archive? Though input data is in JSON format, data
generated from it is binary vectors. Not sure that CouchDB is a good choice
in this case.
What simple (Haskell lib + DB) combination one may advise that support
concurrent read / write access with simple locking (don't need full
transactional support)?
2) Web framework? Don't need AJAX, just basic stuff but simple and easy to
code forms?

Thanks!
