1) Define a job scheduling strategy that will meet business requirement of reporting availability by 6am CST for the following cubes? Show the job scheduling dependencies in a pictorial form so that it is easy to understand.
a. Finance cube (3 hours to build)
b. Warranty cube (4 hours to build)
c. Order cube (2 hours to build)
d. Customer master data (30 min run time)
e. Vendor master data (60 min run time)
f. Product master data (60 min run time)
g. Other Master data (2 hour run time)
Finance and Order cubes cannot run together.
2) Above cubes are used by NA and EU users, NA users will only use NA data and EU users will use only EU data but Master data is common for both NA and EU. The requirement of availability stays same for NA (6AM CST) and for EU reports/cubes should be available by 6am CET.
What changes you need to make to the job scheduling proposal of Question 1 to meet the requirement of Question 2?
CST – NA Central Standard Time.
CET - EU Central European Time.
