Daisy (Data Analysis Integrated Software System) has been designed for the analysis and visualisation of data from synchrotron radiation facility
and other scientific facilities hosted by Institute of High Energy Physics (IHEP).
To address the requirements of the Chinese scientific community, spanning an extensive range from purely algorithmic problems to scientific computing infrastructure,
Daisy sets up a cloud-native platform to support on-site data analysis services with fast feedback and interaction.
Furthermore, the plug-in based application is convenient to process the expected high throughput data flow in parallel at next-generation facilities
such as the High Energy Photon Source (HEPS) and astronomical satellites.
The architecture and some applications of Daisy are described in this article.
