Data entry is the process of entering or updating information in a computer system or database. This can involve typing or scanning data from physical documents, such as forms or invoices, into a digital format that can be stored and analyzed. Data entry is a common task in many industries and is essential for maintaining accurate records and databases. It can be performed manually by individuals, or through automated means such as optical character recognition (OCR) technology. The accuracy and completeness of data entry are critical to ensure that data can be effectively analyzed and used for decision-making purposes.
