Answer 1

In order tp create a Data flow diagram keep the following key notes

always identify the process,external entity,data store and data flow

process is the activity where manipulation of change in data occurs

external entity is the user or a system unit that accesses the data in the DFD

data store is the storing element which stores persistent data which the user produces

data flow simply represents the flow of data within the DFD

in the given solition below i have solved a level 0 DFD using simpler terminologies and easy data flow representations for you to understand .

much shorter conventions and an elaborate DFD can be created using the same data to make it proffessional

NOTE: ROOMS AND CLASS SCHEDULE IS A PROCESS IN THE GIVEN DFD
