tuple spaces and rails

Hey all,

in building an application that will require multiple ajax calls
occuring concurently to different database tables in order to display
data in a form, and then require user input to modify data and then
update it to the database, which invokes a multi-step transaction, that
is, making updates to multiple database tables, I was told in order to
do this using rails and ajax, a good approach would be using tuple
spaces and rails. I never heard of this concept of tuple spaces before.
I went on wikipedia and found the following description. I'm afraid I
don't understand it. Any intepretations? Thanks.

"In computer science, tuples are directly implemented as product types
in most functional programming languages. More commonly, they are
implemented as record types, where the components are labeled instead of
being identified by position alone. This approach is also used in
relational algebra."
