[erlang-questions] Storing tuples directly in Mnesia without records

[Ulf Wiger]

Yes, you can use tuples directly. Unlike ets, mnesia requires
the key to be the second element in the tuple, and the first
element needs to be a label (record_name).

Mnesia will check that the inserted data is a tuple of the
right arity, and that the first element of the tuple is equal
to the 'record_name' of the table (this defaults to the table
name, but can be changed with the {record_name, N} option.

Remember, records are only syntactic sugar for tagged tuples.
