Oracle is changing how it reports cloud revenues — what's it hiding?

Oracle is changing the way it reports its all-important cloud figures every quarter. Where the database vendor used to report two cloud revenue segments: Software-as-a-Service (SaaS) as one and then a combined figure for Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS) as another, smaller, figure, now it is reporting just one figure.
