Raw Data Files
A raw data file is an external
text file whose records contain data values that are organized in
fields. Raw data files are non-proprietary and can be read by a variety
of software programs. The sample raw data files in this book are shown
with a ruler to help you identify where individual fields begin and
end. The ruler is not part of the raw data file.
Figure 6.1 Raw Data File
The table below describes the
record layout for a raw data file that contains readings from exercise
stress tests that have been performed on patients at a health clinic.
Exercise physiologists in the clinic use the test results to prescribe
various exercise therapies. The file contains fixed fields. That is,
values for each variable are in the same location in all records.
