Data bus:

A data bus is a defined path or "highway" for the transmission and distribution of data signals.

CAN:

A Controller Area Network is a data bus system working with two wires, known as bus wires. The bus wires transmit data signals in serial form (one after the other) to the control units connected into the system.

These control units communicate with each other, (i.e. exchange data) via the CANdatabus.
