Is the Hub
to multiple Sat relationship Async or Sync? Meaning if the Hub
is a combin
ation of the satellites
business keys, then is it allowed for some satellites
to get updated, when others do not? If so, then that implies that the business keys will be NULL so is that okay?
Let's take an example of I have four source systems of which have customer info, and workflow wise the customer info will come in initially to either Src1 or Src2, and then will always flow to Src3 & Src4. (Src3 is legacy and Src4 is new up and coming)
--> Src3 & Src4
Option 1.) one Hub
, with 4 satellites
ustomer and each of the 4 satellites
is a separate source.
-- Data will get updated at different intervals, but not all satellites
will receive all customer info.
-- If the Hub
's Business keys are made up of a combin
ation of each satellite
's Business keys, then what happens wen some satellites
will not be updated? NULL Business keys
Option 2.) three hubs
-- Align Hubs
with Customer info that will be updated synchronously thus:
Prospect Customer System 1, it's own Hub
Prospect Customer System 2, it's own Hub
Fulfillment Customer System 3 & 4, it's own Hub
& two Sats
Thank you in advance for any assistance.
