Abstract:[Purpose/significance] In the context of scientific research gradually becoming IT and dataintensive (eScience),reasonably planning research process and scientifically managing data have great significance to projects implementation and data utilization[Method/process] By using empirical research method and surveying the related projects in multiple disciplines,this paper presents the main stages of research activities and data management,and then proposes a dual lifecycle model of scientific research and data[Result/conclusion] The results elaborate how the research and data operation coordinate with each other from specific contents and research standard aspectsThis model gives certain guidance to research activities and corresponding data service when research teams are the main body of responsibility[Limitations] The proposed dual lifecycle model may apply to most of research activities,but some research would add or subtract some stages according to their actual project situation
