well, i am not the first to notice that you have simply missed the 
closing "." for the function 'write' which is a syntax error.

and this is exactly why i always put "dots" on a new line:

new() ->
	[]
.

destroy(Db) ->
	ok
.

write(Key, Element, Db) ->
	[ {Key, Element} | Db ]
.


I also fixed some other mistakes in your snippet, look for them.
And do not forget to export your 'write/3'

'export_all' compiler's option is very nice For debugging:
-compile(export_all).
