I admit that this is basically a duplicate question of Use freebase data on local server? but I need more detailed answers than have already been given there

SPARQL is the query language to query RDF, it allows to write SQL-alike queries. Most RDF databases implement SPARQL interfaces. Moreover, Freebase allows you to export data in RDF so you could potentially use that data directly in an RDF database and query it with SPARQL.

I would have a look at this tutorial to get a better sense of SPARQL.

If you are going to handle a big dataset, like freebase, I would use 4store together with any of the Python clients. 4store exposes SPARQL via HTTP, you can make HTTP requests to assert, remove and query data. It also handles resultsets in JSON, and this is really handy with Python. I have used this infrastructure in several projects, not with CherryPy but with Django, but I guess that this difference doesn't really matter.
