file and database system

File and database processing

Also known as file and database maintenance. This emphasizes that an organization's files and databases must be maintained by its transaction processing systems so that they are always correct and up to date.

Document and Report Generation Documents produced by transaction processing systems are called transaction documents. There are several major types of such documents:

Action documents - are documents that initiate actions or transactions on the part of their recipient.

Information documents - These documents relate, confirm, or prove to their recipients that transactions have occurred.

Turnaround documents - some types of transaction documents are designed to be read by magnetic or optical scanning devices. Forms produced in this manner are known as turnaround documents because they are designed to be returned to the sender.
