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. -- https://mail.python.org/mailman/listinfo/python-list
