What is serviceability?
Stores, manages, and processes data and applications over the Internet
What is cloud computing?
Includes fixed data incapable of change in the event of a user action

What is multi-tenancy?
Ensures that every data value is correct and accurate
What is data validation?
Reasons for low-quality information
