How to do caching in SSAS

Hi All

Can anyone help me out in this.

In my database i have stored value for new customer in cache table using below query.

But i want to do the same in SSAS without using cache table.

Here senario is i want count of customers present in current date but not present in previous date(New customers).

For e.g. I want count of customers present in '2013-01-05'  but not present in '2013-01-04' then present in '2013-01-04'  but not in '2013-01-03' so on...

insert into tb_Date
select distinct Date,Freq_ID  from Tb_Customer
order by Date desc

Declare @count int,@CountEnd int

set @count = 1
set @CountEnd = (select count (1) from tb_Date)

Declare @currnt_date datetime
Declare @compr_date datetime

while (@count < @CountEnd)
begin

set @currnt_date = (select  Date from tb_Date where ID = @count )
set @compr_date = (select top 1 Date from tb_Date where Date < @currnt_date)

insert into New_Customer_Count
select COUNT(Distinct Customer_id) as Total_Count
from Tb_Customer A
where Date = @currnt_date
and Customer_id not in
(
select Customer_id from Tb_Customer B
where  Date = @compr_date
)
set @count = @count + 1

end

thanks in advance
