Data entry is the process of digitizing data by entering it into a computer system for organization and management purposes. It is a person-based process [ 1 ] and is "one of the important basic" [ 2 ] tasks needed when no machine-readable version of the information is readily available for planned computer-based analysis or processing.
[1] [2] [3] Typically a DCS displays a form that accepts data input from a user and then validates that input prior to committing the data to persistent storage such as a database. Many computer systems implement data entry forms, but data collection systems tend to be more complex, with possibly many related forms containing detailed user ...

Advisory actions typically allow data to be entered unchanged but sends a message to the source actor indicating those validation issues that were encountered. This is most suitable for non-interactive system, for systems where the change is not business critical, for cleansing steps of existing data and for verification steps of an entry process.

There is a nine-step guide for organizations that wish to improve data quality: [3] [4] Declare a high-level commitment to a data quality culture; Drive process reengineering at the executive level; Spend money to improve the data entry environment; Spend money to improve application integration; Spend money to change how processes work
Data verification helps to determine whether data was accurately translated when data is transferred from one source to another, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss .
Data flow diagram with data storage, data flows, function and interface. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself.
