A single training is a continuous training which may stretch for a period of 2-3 days. This approach may be good in certain conditions. It's usually tough for users to take break from their routine job and spend 2-3 days, but certain occasions, like starting of month/quarter/year, may be less taxing for them and they can spend this time. There can also be occasions when there is a long weekend and the users may be willing to accommodate.

This approach will work well where the users are spread in multiple cities and it's easier to get all of them together for 2-3 days. The single continuous training works well for those users who are already familiar with BI software.
