Write-Optimized DSO - Delta

363 Views

Hi,

Write-Optimized DSO has request-level delta and standard DSO has record-level delta. I know each new request is a delta for WO-DSO.

1. Could someone explain me how the request delta process works when compared to before-image and after-image concept of Standard DSO?

Eg: If there is 1 record in the initial load into BI.

Purch. Ord No. Qty

1 100

The delta record:

Purch. Ord No. Qty

1 200

For Standard DSO, in the change log, there will be 2 records:

Purch. Ord No. Qty

1 100

1 -100

1 +200

How different is the delta process for WO-DSO?

2. Are there any disadvantages with delta process of WO-DSO?

3. In order to load 1.5-2 mill. records into WO-DSO on a daily basis, how much time will it take on an average?

Please let me know.

Thanks in advance.
