Hi Hasitha, All three of these are for different purposes.
An experiment corresponds to an "experiment" or "investigation" done by a scientist/user and might require multiple workflows (in a hierarchal fashion) to accomplish it. A single workflow most of the times has many services in it. So the hierarchy is experiment id -> (one or more workflow ids) -> one or more service id's.
