Exactly who and when did the change from 'data warehouse', then later to 'business intelligence' and now 'Big Data' occur. Everytime a name change in an industry occurs (accounting software becomes ERP, Contact management becomes Sales force automation, becomes Customer Relationship Management)
Timeshare became managed services, became ASP, became hosting, became SaaS, became 'Cloud Computing'.
This is just stupid
