Everything is cryptic in this field.
This is what I suggest we do, use the Django server and some scripts to make multivariate data from some other sources of data. So start with data X, Y, Z ... then make (X,Y,Z,...) as collection of tuples. This is standard procedure in most data mining packages.
The script in Mathematica is trivial and easy to implement.
Then after computing the tuples, apply filters and transforms.
