Introduction
Imagine this situation: you are entering new customer records into your database. You entered 98 records and are working on entering the 99th customer record and your machine goes down. Are the first 98 records you entered lost? No, Progress does just what you want in this situation:
This is just one simple scenario. Suppose the procedure was updating multiple tables. You want to make sure that Progress saves any completed changes and discards partial changes in all tables.
System failures are just one kind of error. There are other kinds of errors that can occur while a procedure is running. Regardless of the kind of error you are dealing with, data integrity is all important. Data integrity means that Progress stores completed data and does not store incomplete data in the database. Progress uses transactions to automatically handle this processing.
