Abstract：In this talk, I will briefly discuss our recent data-oriented research works in the GRB field. I will first review our fully automatic GRB data analyzing system. I will then talk about several case studies that directly utilized the results of our system. In particular, I will focus on prompt emission data of the gravitational wave GRB 170817A and discuss our current understanding of this first NS-NS merger event,  including its event rates, ejecta topology, radiation mechanism and what can learn from the 1.7 s time delay between the GRB and the gravitational wave signal.
