Advice on database volume

Hi all,
I'm new to datawarehousing. I've built a DW with two fact tables, each one
will be added with more than 5 to 10 millions rows each day. Do you think
that this volume is compatible with Analysis Services 2005 or do I have to
change the model I use, by creating a fact table for each customer I have
(for instance).
Second question: if the awnser of the previous question is that I can keep
the model I've built, will I have to investigate cube partition ?
thank's.

You can work with this volume of data in Analysis Services 2005 without
changing your schema (and I strongly suggest you to not change your
schema!).
You can use partitions to handle this volume of data without having a
single big partition that is hard to process if for whatever reasons
you need to full process your cube.
Be careful with aggregation design - you really need preaggregations on
this volume of data.

What do you mean exactly by "aggregation design"?
What is exactly preaggregation? Do you know some references on the web?
Thanks
