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!
