Hauptdatenquelle

Hauptdatenquelle, also known as primary data source, refers to the original and firsthand information that is collected directly from the subject of study or research. This type of data is gathered through primary research methods, such as surveys, interviews, observations, or experiments. Hauptdatenquelle is distinct from secondary data sources, which are derived from existing data collected by others. Primary data is considered more reliable and relevant to the specific research question, as it is collected in the context of the study and is not influenced by the biases or interpretations of previous researchers. However, collecting primary data can be time-consuming and resource-intensive. It is important to ensure that the methods used to collect primary data are valid, reliable, and ethical. Proper documentation and data management practices should also be followed to maintain the integrity of the data. In some fields, such as social sciences and humanities, primary data may also include historical documents, artifacts, or other physical evidence that has been preserved and is directly relevant to the research topic.
