Data processing is the means by which raw data is turned into usable information. Manual data processing is the physical entering and organization of data. Though most data processing is now done by computers, there was a time when collected data was recorded and tabulated by hand in paper spreadsheets. The tables were used to calculate, analyze and summarize data, but calculations were done by
. hand or calculator. The limitations of stacks of paper, human error and the cost of man-hours meant that manual data processing could not handle the increasing demands of modern data collection.The development of computers and programs designed for manipulating data rendered manual data processing obsolete. Computer programs are much more efficient and capable of handling an enormous volume of data which would take human processors inordinate amounts of time to complete. In addition, computers can quickly analyze algorithms and other patterns automatically, and present several representations simultaneously, so that analysts can compare the results. This means that methods for manual data processing are forgotten except for historical textbooks and people with an interest in history, but they are useless in modern times; since using older, manual methods to process modern data is not feasible, it is important to have redundant computer systems for backup purposes.As computer programs grow more sophisticated, computer-related tasks that were originally done by hand are done by software. For example, when using spreadsheets to perform complicated accounting tasks, it was once necessary that a person had to copy and paste several fields at each step of the process. This manual component is no longer necessary with advanced programs designed for the application and correctly configured. Programmers are continually looking for ways to allow software to perform the tasks that humans must still do when working with software, whether it is data entry or data analysis.
