Because there are alternatives that need to be investigated on a per
problem basis for the best database.

etc. Python only has SQLite3 as standard but there are alternatives. I
have been using PyMongo quite successfully.

It is not clear that the original table works better with the relational
model compared to one of the key-value stores or document stores. It
might. But I no longer always go to SQL for persistence as I used to a

There are various articles around the Web comparing and contrasting
these various models. Some of the articles are even reasonable :-)
