Data entry is a fundamental process of inputting, organizing, and storing data in a computer system or database. It involves manually or electronically entering information from various sources, such as paper documents, forms, or digital files, into a structured format that can be easily managed and utilized. Data entry requires accuracy, attention to detail, and adherence to data formatting standards to ensure reliable and error-free data. The entered data can then be used for analysis, reporting, decision-making, or other operational purposes.
