Data Input Accuracy
Why Accuracy of Data Input is Important
The continuous operation in today's many systems depends on the accuracy of data that the systems use. As the amount of data increases, it is critical to ensure that every data input and used in a system is error-free to eliminate unwanted system problems.
Computer systems, software, and applications are basically created to provide efficiency in accomplishing a task. If the data used by a system is inaccurate, what help and sense will a computer system provide to its users? Accuracy of data input is important because data is considered as the life of a successful system operation. Jack Olson has the following view on the importance of data. Such importance provides the reason why accuracy of data input is similarly important.
Corporate databases are filled with data that reflects their business activities. This data is collected through routine business processes. However, its usefulness goes far beyond the operational applications that generate it. Corporations have been using data in data warehouses and decision support systems, integrating with other applications and connecting with external applications over the Internet. Data is more precious than ever before as the uses of data expands.
There are diverse methods used by businesses and companies to input data into their systems. This includes manual script, external keyboard input, optical image scan input, graffiti input, automated input from other sources,...
Following are recommendations on which method of data input would be best for the several situations.
Printed Questionnaires
As its name implies, printed questionnaires is a form of document that is printed or written on any writing material such as the paper.
In this type of situation, the method of data input that would best to apply is the manual script method.
Printed questionnaires are basically something that is on the form of a hard copy. The easiest way to input data on such is to write on the questionnaire manually. It would be impractical to use other methods of data input, such as optimal image scan, to provide an answer to every question. Moreover, since questionnaires generally need honest and reliable answers, information that come directly from the person who fills-up the questionnaire, and are directly provided by the person through his own penmanship can be considered as accurate data. This is of course unless the person is not honest in providing his answers. The reliability of such manually scripted information best applies to opinion-based questionnaires.
Telephone Survey
For telephone surveys, as its name implies, is generally conducted with the use of telephones. Such survey may involve an operator who speaks to a participant, asks questions, and input the participant's answers to a computer. It may also involve voice recording of the partcipant's answer. Choosing from…

For resumes, the most pretentious output method would be transforming the XML file into a PDF file. The same applies for memorandums. Statistical reports and company annual reports are linked to output methods like: console, file, log file rolling, HTTP Post, TCP broadcast, UDP broadcast, or logging templates. The hard disk is mostly used for storing large amounts of digital encoded data, like video data, audio data and others. It provides efficient
Accuracy of data input is important. What method of data input would be best for each of the following situations and why: Printed questionnaires - Beyond using a manually-based approach to capture this data and transcribing it onto computer screens, the best possible approach would be code the questionnaire so responses could be read with Optical Character Recognition (OCR) software (Nibler, 1993). Designing an on-screen software application that will allow for those
Data Input Printed Questionnaires. Manual data input method is appropriate for printed questionnaires. Since questionnaires are printed and therefore can be accessed as a hardcopy, the only way to input data on it is through manual writing. If the data will be transferred into a database, the appropriate method of data input is through data entry. Data entry on a computer is the appropriate method for this situation. For instance, while
Data Input, Output, Storage Devices and Determining the Speed of a Computer This paper has made use of the different input and output methods for computers as well as studied the differences between primary and secondary storage. It also checks for the roles of different computer parts in the overall working of the computer. In computer terminology, data is something that is unprocessed and raw, which does not have a series
Since poor data quality within a system often results in poor business decisions being made from this data, it is very important that each administrator or system architect look at each customer or end-user differently, in their own unique light. Since each end-user is different, and the needs of the customer often stem from the warehouse's ability to accurately store quality information, a system that dates back to the 1970's
From a convenience aspect, as the hand held computers typically have smaller screens, shorter text messages would be the most convenient to read and interpret. Color photograph - There are a variety of output devices that can produce acceptable quality color photographs. At the low end of the market there are color inkjet printers that rely on special papers and inks to product high quality photographic prints. At the higher
