Based on the key value of the database, can someone explain to me how to use them in practice?

Question

There seems to be a big push for databases based on keys / values, which I assume are memcache.

Is a value usually a kind of compilation or XML file that will contain more meaningful data?

If so, is it usually faster to deserialize the data, and then traditionally do JOINS and select tables that return a row-based result set?
