Note that you can have nested arrays and objects. The driver will always
store an associative array as an object in the database. A
numerically indexed array is stored as an array in case the keys start at
0 and are not interrupted, and as an object if the array keys don't start
at 0 or have gaps (ie: <em>0, 1, 4, 5</em>).
