Topic: multi-stage user interaction with big data but no models
I am new to Rails and have a question about architecture of a project which essentially is a UI for an OLAP kind of a system, except that I am trying to keep it simple and cheap (i.e. no huge databases with multidimensional schemas).
OK, now I think a disclaimer is in order: I understand that RoR is MVC, and so doing things with data which is not represented by model(s) is not quite normal. But I still think there are cases where you just can't store all the data in models.
So, basically, I have a lot of data, which has many dimensions. And what I need is a UI which will ask user to provide definitions of the
... oops. somehow half the post didn't make it through =( Editing for the missed content:
... so, the point is: Users will need to answer several (i.e. 2 or more) questions about the dimensions of the "slice" of the data cube (or a hypercube). Each answer will restrict the data which will be rendered to them in the end - and the second question will depend on the answer to the first one, and so on. And, naturally, I want to be able to keep data between these steps. And rails actions don't exactly share variables - which in my case will be nested hashes up to 100MB in size. So I am trying to figure out how to organize this...
