This exercise assumes that you have completed the Graphical Table Mapping Exercise. If you have not done so already, complete the Graphical Table Mapping Exercise first.

After completing this exercise, you will be able to:

• Use the msgdiff tool to analyze the differences between HL7 messages, and
• Perform HL7 <-> HL7 transformation to transform one format of HL7 to another.

	Before starting, download this pre_translation.txt file, which contains one sample ORU^R01 message before performing HL7 <-> HL7 transformation, while post_translation.txt is the message after HL7 <-> translation. Save these files into a directory of your choice so that you may use them later on for this exercise.
