Data Model - Idea Required

Question

Hello,
I have 4 different flat files. Each File will have about 16 lakh records every year.
I want to know what is best possible data flow i can use. Like 4 DSO from 4 data sources then whether to use one DSO collecting all or 4 DSO or 4 Cubes and so on?
Also we have to store previous 3 years data for each flat file. Also my question is if i can store this in same target as we are discussing above or different for each file?
Please suggest

Hi Syed,
As  per your requiremnt you  need  to concentarte on the following Performance points.
As per BI 7 i am giving the Info
1. Data is huge .So you need to use howmany DSO?
    -  As per my exp create a sepaarte DSO for each DS and later you can create a separate DSO on the top based if you want to maintain a unique records based on the four DSO's.
2. Data laoing issue
          - Activating Data is also one issue.As you mentioned its FF if possible use Write Optimized DSO in the first layer.
3. Cube Design
     - Based on the above points what type of Data is coming and you want to maintain a separate Cube for each area.
        Ex : wht we follow in SD,MM etc......
OR create One Cube and maintain the relevant Data then later use Multi Provider on top of DSO's and Cube for reporting.

Ram.
