Batch and file exchange still matter

This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
respect batch and files where they fit.
Planned topics
- Batch suits large volumes and tolerant latency: nightly price lists, financial postings.
- Files are common with ERP, banks, and carriers; formats and schedules are contracts.
- Make them safe: names, checksums, idempotent loads, reconciliation, and alerts for late files.
- Replace them only when the need justifies the change.
Draft outline details
Demonstration
