Data entry is the professional term for entering information into a computer or data-recording system using an electronic or mechanical device. Some companies hire workers solely as data-entry clerks or data-entry specialists and others hire employees to fill various roles that might include data entry as part of their general job requirements. Data entry isn't the same as typing because it specifically deals with entering and storing data so others can use it for evaluative purposes.
When information is entered into computers or other types of data-recording systems, data-entry clerks verify the information to make sure it's accurate and complete. For example, some clerks enter patient information into hospital databases and ensure that names, addresses, medical information and dates of service are entered correctly. Data entry isn't useful to employers unless the information is truthful, reliable and accurate. Date-entry clerks proofread information before recording it to reduce mistakes, misspellings and discrepancies.
