सारांश	Archaeological stratigraphy is the systematic excavation and recording of soil layers, deposits, and features at an archaeological site in order to establish the relative chronological sequence of human activity. Grounded in the geological law of superposition — that lower layers are older than those above — it uses the Harris Matrix as a formal tool to map depositional relationships and reconstruct site history layer by layer.	The oral history method is a qualitative research approach in which researchers conduct in-depth, recorded interviews with individuals who have direct personal experience of a historical event, social process, or community life. It captures subjective perspectives, memory, and lived experience that written records rarely preserve, making it indispensable for recovering voices absent from official archives — particularly those of marginalised communities, minority groups, and ordinary people.
