Hi,
although I have the same problem as Avraham with getting a close view on
your schema I will try to add my 2 cents to your question.

Unless you have a specific need of a NoSQL feature the fact that you
have many related tables seems a better use case for SQL relational
database.
In general I Think Alex is right that one should use NoSQL only if there
is a special need to do so (like scalability or frequently changing
schemas, you name it ...).
So what might be the options in a NoSQL-world:
Either a document store or a key-value store.
With both there is no native support for relations. With a document
store you might use something like nesting related entities but that
reaches its limits when it comes to m:n-relationships.
With a key-value-store you can of course store relations by storing the
related object's id under the parent's key. This should also work for
many-to-many-relationships.
But to me both tools seems to be abused using them this way.
What imho might be an option is a graph-database because by definition
this is highly normalized and has all the relations already in place.
Maybe you want to have a look at Neo4j (http://www.neo4j.org/) which
provides you with a property-graph-engine.
There is a library which claims to integrate Neo4j into Django
(https://github.com/scholrly/neo4django). There are other python
libraries as well (s. http://www.neo4j.org/develop/python).
I tried py2neo but not enough to finally judge it.
I played with Neo4j using their Webinterface and I liked the idea of
storing data as graphs very much.
So maybe you find a way to fit your model into a graph structure and can
find out if your typical queries will be supported by Neo4J.
Feel free to send me your schema and I will try to have a look at it
with regard to Neo4j (but w/o promising that this might be of much help
;-) ).
With best regards
Carsten Reimer
