Data entry is a very broad discipline. In most cases, it means that an employee takes data stored in a certain medium and inserts these into a computer system through a data entry interface. The original content can come from any source: it could be available on paper, scanned documents, online or stored in picture, audio or video files. In its simplest form, data entry just means copy-pasting data from the source to the destination system. It becomes more complicated if the data has to be researched, identified or need interpretation or the application of business rules before these are entered into a system.
