This essay discusses the issue of data management in life history research. Frequently asked questions in life course research include the status of the individual at a specific time, and what kind of household or organization she or he belonged to at the time. This essay illustrates that Relational Database Management System (DBMS) is the ideal tool for efficient data-management in life course research, using as an example our research project, “The Discharge of Four Thousand Coal Minners of Jyoban Tanko K.K”. This essay suggests that designing an appropriate database leads to improved conceptualization in the data analysis stage.
