Although most data entered into a computer are stored in a database, a significant amount is stored in a spreadsheet. [17] The use of spreadsheets instead of databases for data entry can be traced to the 1979 introduction of Visicalc, [18] and what some consider the wrong place [19] for storing computational data continues.

An example of a data-integrity mechanism is the parent-and-child relationship of related records. If a parent record owns one or more related child records all of the referential integrity processes are handled by the database itself, which automatically ensures the accuracy and integrity of the data so that no child record can exist without a parent (also called being orphaned) and that no ...
