Cube, Build, Deploy, Process

Dear all,

I'd like to get simple and clear explanation of the cube in data mining, and 3 notions we encounter a lot : Build, Deploy, and Process.

(1) What is the cube that is created when we deploy a mining solution/project?
I wonder what type of cubes they are because although the dialog on deploy/process
show that cube, after successful deployment we still don't see the cube in Cubes folder
of the project.

(2) Why the SQL Server created that cube? Even though we process only one table
and only use case-table (without nested table)

(3) Can someone explain these 3 concepts with CLEAR differences between them?
(A) Build
(B) Deploy
(C) Process

As far as I know, the stages are like that : build, then deploy, then process. Also, it seems
to me that those operations do not create objects inside 'Relational' database, but create
objects (binary and text, with text files usually in XMLA programming language) in the
related project's folders and subfolders. Any good explanation is appreciated.
