Use the classic example of the filing cabinet to introduce
the need for electronic databases. Explain to students that
data entry in databases can be performed in several ways.
(i.e. dictation, keyboard, mouse, scanners, PDAs.)
Use the PowerPoint presentation to provide the information
needed for this competency. This can be done
electronically with a data projector, or you may choose to
print each slide on a transparency. It is recommended that
you give the students a copy of the PowerPoint handouts
for their notes.
