Conducting
user interviews
was the next subject of discussion. We examined the four
issues you must address during these interviews, along with the techniques you use to
address them. Next, we discussed conducting
management interviews.
Here you learned
about the issues and techniques these interviews incorporate.
Finally, we discussed the process of
compiling a list of fields
based on the list of character-
istics and the characteristics that appear in the samples. You learned that you decompose
the field list into two separate lists: a
Preliminary Field List
and a
Calculated Field List.
The Preliminary Field List enumerates the organization's fundamental data requirements
and establishes the core set of fields you must define in the database. The Calculated Field
List consists of fields that contain values resulting from string concatenations or mathem-
atical expressions.
