সারসংক্ষেপ	Field-based ethnography is a qualitative research design in which the researcher immerses themselves in a social setting or community over an extended period, observing and participating in everyday life to understand cultural practices, meanings, and social dynamics from an insider perspective. It is the classical form of ethnography, grounded in sustained physical presence at a research site, and distinguished from archival, virtual, or document-only approaches by its central reliance on direct, embodied fieldwork.	Longitudinal ethnography is a qualitative research design in which a researcher conducts sustained, repeated fieldwork with the same community, organisation, or group across an extended period — months to decades. By returning to the field at multiple time points, the researcher captures how social processes, meanings, and structures evolve, making it the only qualitative method capable of directly observing change and continuity in lived experience.
