The Space Solar Telescope (SST) with five payloads onboard is now under researching, developing and manufacturing. These payloads with different observation modes and different original data formats will produce up to 50GB scientific data per day. On board data processing units, such as integration, compression and computation unit, are needed to reduce the data amount to about 10GB to fit the ability of X-band scientific data translating system. And data encoding unit is also necessary to transfer the data into transmittable data format. So the scientific data will have different data formats. In Researching and Developing the SDPU of the SST, how to manage the science data storied in Data Storage Unit (DUS) has become one of the important issues, for the data format should be very convenient for post processing and data recovering on ground. In this paper, the detailed science data flow, corresponding to different observation modes, different data processing sequences and different data formats, will be discussed. Tables and figures are also used to show preliminarily the complex configurations of SST data format.
