Using XML with Legacy Business Applications

X12 to XML: Detail Design

If you have reviewed Chapters 7 and 8, you should have a fairly good understanding of the architecture and basic coding approach used for these utilities. You will find that the utilities developed in this chapter have many similarities to those developed in the two previous chapters. However, X12 interchanges are very different in some key aspects from CSV files and flat files, so we will see some interesting processing differences. As with Chapter 8 I will focus on the unique aspects of these utilities and refer you back to Chapter 7 if you wish to better understand the architecture and coding approach.
