In data flow diagrams, the lines between "boxes" represent data that flows between components of a system. Because these only show the flow of data, they do not give an indication of sequencing.In activity diagrams, those lines are simply transitions between activities and do not represent data flow at all. They more represent the sequencing of activities and decisions. You can tell from these what order things happen in.

DFD means data flow diagram and database is an integral part of the DFD. It is not possible to draw a DFD without a database, since there has to be a place for data storage in the overall business process flow.
