In the business computer system of the future, several different computers in several different places will work together on their assignments, according to Clarence W. Spangle president of Honeywell Information Systems.
He predicts these "distributive systems," as they are called, will make computer management a "high risk, high visibility" job in business organizations.
Spangle was in Washington yesterday to give the opening speech at a convention of the Data Processing Management Association.
He told the computer users group their jobs will get more difficulty and more dangerous as data processing enters its third phase of development.
Originally, Spangle explained , computers were used in accounting departments. Because accounting was a centralized function, central computer rooms developed first.
Then as smaller, cheaper computers became available, these was an era of profileration in which every department or branch of a business got its own hardware.
This mass of mini-computers often means duplication, data incompatibility of computer systems, lack of central controls and higher costs, he said.
By linking computers together - either with telephone lines or computers - a network with the advantages of both centralized and decentralized computing can be created, he said. Thus system can be more powerful than any indivual computer, yet each branch system can still perform specialized needs.
Spangle cited and unnamed Honeywell client with 25 manufacturing plants. Each plant computer handles its own problems, but can draw on the larger capacity of the cenrtral computer when needed. The system in turn, can utilize the specialized abilities of any branch system on demand and has immediate access to any branch information.
