Collect Data

Data collection, also known as data gathering, is the first step in the data processing and analysis workflow. It refers to the process of obtaining raw information from various sources using either manual or automated techniques. The sources are diverse, including databases, sensors, the internet, business systems, and public data sources, and the data collected can be either structured or unstructured. Common methods include surveys, manual entry, and automated techniques using web crawlers, API interfaces, or log systems. This process needs to follow core principles like accuracy, completeness, timeliness, consistency, and security. Data collection forms the foundation for decision-making and innovation in statistics, business intelligence, scientific research, and many other fields.
