Database Description (.dsc) File Example
This document contains an example of a database description (.dsc) file. The various sections that make up a .dsc file are labeled with section headings that are included in the example below as comments. Use this example in conjunction with the .dsc reference pages to create your own database description file.
| Note: |
The individual .dsc reference pages linked to below contain specific syntax information and guidelines for each section of the .dsc file. It is recommended that you read these pages carefully to create a functional .dsc file.
|
Syntax Notes
Pay close attention to the following syntax elements as you create your .dsc file and examine the example below:
- Comments are denoted with "/*" and "*/" to begin and end the file documentation.
- The "\" symbol shown below acts as a line continuation marker to break long lines of text in a file.
- When listing multiple tag paths, or field ids, in the .dsc definitions, separate each tag path with a comma followed by a blank space.
- The first field id listed in an index definition should start at the beginning of the line or directly after file documentation - DO NOT include a blank space before the field id, but do include a comma followed by a blank space after it.
