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.”
