Data entry, a person-based process, is "one of the important basic" tasks needed when no machine-readable version of the information for planned computer-based analysis or processing is readily available.
Sometimes what is needed is "information about information (that) can be greater than the value of the information itself." It can also involve filling in required information which is then "data-entered" from what was written on the research document, such as the growth in available items in a category.:68 This is a higher level of abstraction than Metadata, "information about data."
Historically, devices lacking any pre-processing capabilities were used.
Although most data entered into a computer are stored in a database, a significant amount is stored in a spreadsheet. The use of spreadsheets instead of databases for data entry can be traced to the 1979 introduction of Visicalc, and what some consider the wrong place for storing computational data continues.
The search for assurance about the accuracy of the data entry process predates computer keyboards and online data entry. IBM even went beyond their 056 Card Verifier and developed their quiter IBM 059 model.
Modern techniques go beyond mere range checks, especially when the new data can be evaluated using probability about an event.
A medical school tested its second year students and found their data entry skills, needed if they're to do small-scale unfunded research as part of their training, were below what they considered acceptable.
