Cloud Computing and SOA Convergence in Your Enterprise: A Step ...

Working from Your Services to the Clouds 111
Using a simplistic approach that allows us to cover this problem domain/

Del_Customer
Edit_Customer
Add_Sales
Del_Sales
Edit_Sale
Perform_Credit_Check
Inventory Management
Add_Product
Del_Product

Order_Product
General Ledger
Add_Customer
Del_Customer
Update_Customer
Add_Account
Update_Account
Add_Product
Del_Product
Update_Product
Record_Sales
