data entries of different forms can be performed in a very less time with high accuracy. data can be accepted of the form of audio, video and pictorial form. high quality of picture or photographs can be shot . some types of mathematical data can be entered in short time . some programing language codes can a;so be written or data of codes can be entered as required. A data entry clerk is a member of staff employed to enter or update data into a computer system. Data is often entered into a computer from paper documents using a keyboard. The keyboards used can often have special keys and multiple colors to help in the task and speed up the work. 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. This is a higher level of abstraction than Metadata, "information about data."Data entry is often done with a keyboard and at times also using a mouse, although a manually-fed scanner may be involved. 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 introduction of Visicalc, and what some consider the wrong place for storing computational data continues. Format control and specialized data validation are reasons that have been cited for using database-oriented data entry software. 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. ...............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
