Default Creating too many dimensions - 05-20-2004 , 12:28 PM






Hi,

I am afraid that based on my user requirements I may be going down a
slippery slope of dimension drowning

Here is the situation,
Fact table: order-line

On the fact table we have typical dimension style data like:
Date/Item/Customer/Carrier/Salesman

Now in the case of "Items", people may want to view data in terms of:
Product Type
Item Category
Manufacturer
Genre...

These ways of looking at an items are unrelated in terms of
heirarechies.
So for items I already have 4 dimensions for ways at looking Item
Data. For Customers I have 6 ways of looking at them.

So basically I am creating a dimension for each type of view my users
want. I am already at 19 dimensions.

Is what I am doing correct?

Any help/advise would be appreciated!

Regards,

I dont think that sounds like too many.

Just order them correctly, make them fit into the 64k limit, and you should
be good to go.

How many records are you talking about?

How many members per dimension?
