Topic: tuple space/rails/ajax/data driven application

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."
