I am trying to learn about databases and at the moment starting to read general stuff about multidimensional database design. The trouble is, I don't even know the basics about databases, like what is natural key (same as primary key made of single components?) or surrogate key... Could anyone explain …
It seems to me that database design has a few things in common with systems analysis, but here are two tutorial sites about databases and one that my friend told me about systems analysis - sorry it is just a portal to more tutorials to choose and pick.

The End.
