Introduction to Business Intelligence

"The availability of documents in machine-readable form is a basic requirement of the system. Typewriters with paper-tape punching attachments are already used extensively in information processing and communication operations. Their use as standard equipment in the future would provide machine-readable records of new information. The transcription of old records would pose a problem, since in most cases it would be uneconomical to perform this job by hand. The mechanization of this operation will therefore have to wait until print-reading devices have been perfected".
