This paper proposes a big data query system for customized queries based on specific business needs. This paper introduces the components and structure of the query system. ANTLR tools are used as language recognizer to design and implement a customized SQL dialect. The system builds a simpler and easier query interface on Spark SQL, which satisfies the query requirements of the Internet user behavior analysis platform.

Video is an important new instrument for sociological research, sometimes welcomed as the ‘microscope’ of social science. It provides access to important and otherwise difficult to examine aspects of human interaction. Moreover, because video captures practice in its lived production as ‘another next first time’ (Garfinkel 2002), it makes it possible to study practical creativity - the way in which people invent new practices. In this paper, I probe the microscope metaphor through concrete examples from my work with landscape architects and computer scientists in participatory technology research and design projects.
