I studied Punch cards and punch card equipment, readers and processors to do business accounting for businesses in the Los Angeles area then. I also learned to program computers in Cobol and Fortran
Cobol is a business language still used today by the way and Fortran then was more useful then for mathematical and scientific processes.
https://en.wikipedia.org/wiki/COBOLCOBOL (/ˈkoʊbɒl, -bɔːl/; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is imperative, procedural and, since 2002, object-oriented.
https://en.wikipedia.org/wiki/FortranFortran (/ˈfɔːrtræn/; formerly FORTRAN, derived from Formula Translation) is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
begin quote from:
https://en.wikipedia.org/wiki/Data_processingData processing is, generally, "the collection and manipulation of items of data to produce meaningful information." In this sense it can be considered a subset of information processing, "the change (processing) of information in any manner detectable by an observer."
https://www.britannica.com/technology/data-processingData processing, Manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing.
https://planningtank.com/computer-applications/data-processingJun 15, 2017 - Data processing is the conversion of data into usable and desired form. This conversion or “processing” is carried out using a predefined sequence of operations either manually or automatically. Most of the data processing is done by using computers and thus done automatically.

The process includes activities like dataentry, summary, calculation, storage, etc. Useful and informative output is presented in various appropriate forms such ...
