8. Tracking and Back-End Order Entry
Interchange allows the entry of orders into a system through one of several methods. The AsciiBackend capability allows submission of parameters to an external order entry script. Support for SQL allows the entry of orders directly into an SQL database. Orders can be written to an ASCII file. They can be formatted precisely for e-mail-based systems. The orders can be placed in a DBM file. Finally, embedded Perl allows completely flexible order entry, including real-time credit card verification and settlement.
