Tóm tắt	Digital case study research applies the classic bounded case study framework to phenomena that are situated in, or mediated by, digital environments. Drawing on Robert Yin's foundational case study methodology, it investigates a contemporary phenomenon in depth within its real-world digital context — using online documents, social media archives, virtual interviews, website content, and other digital artifacts as primary evidence. The approach is particularly suited to studying how individuals, groups, or organisations behave in online spaces.	Document analysis is a systematic qualitative research method for examining written, visual, or audiovisual sources—such as policy documents, historical records, organizational records, media reports, emails, social media posts, photographs, or videos—to extract meaning, identify patterns, and understand social phenomena. Developed by Weber and Mannheim in early 20th-century sociology, the method bridges historical research, content analysis, and textual interpretation. Document analysis is used across disciplines to understand organizational change, policy evolution, media representation, historical events, and cultural meaning. Documents provide evidence of what organizations, institutions, or societies value, decide, and communicate, often revealing contradictions between policy and practice.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
