A Data Dictionary describes the overall organization of a data file
. In other words, it gives a description of how data are stored in a file. CSPro requires that a data dictionary be created for each different file being used.
Each dictionary will allow you to give text labels
for all levels
, and value sets
in the file. It also allows you to describe the organization of each record in the file and the characteristics of each item
in the record: names, position in the data record, type of data, length, number of decimal places, valid values, and other documentation.
Before you convert the information from a questionnaire to computer-readable form, you usually create a data dictionary. You can also create a data dictionary for an existing data file
if you have a description of its contents showing the location of each item.
