Data and DEF Files

What is a data file?

Data files contain data to be imported into the system. This data will be read by the DEF file. Data files must be formatted one of two ways in order to be read by the system; that of Fixed-Width or Comma Separated Variable (CSV). Each of these formats is read differently by definition files.

What is a DEF file?

The definition file describes how to interpret the information contained in the separate data file. The definition and data files can have any filename.

What is the difference between CSV and fixed-width data files?

In the CSV format, data is separated by commas, while in the fixed-width format, similar data appears in the same position of each line of data.
