When you say "database" here, you're really talking about relational 
databases.  There are other kinds.

In MongoDB, for example, storing a list of lists of strings is a 
perfectly reasonable and straight-forward thing to do.  Anything which 
can be represented by bson (which is more or less the same as anything 
which can be represented by json) can be inserted directly.
