98 98  As correlations of different physical properties are often required all data at FLASH are indexed by the [[trainID>>doc:FLASHUSER.TrainID]], which identify each of FLASH's pulse trains. The during a beamtime recorded data are stored via a Data Acquisition System ( [[DAQ>>doc:FLASHUSER.Information about the FLASH DAQ system]]) which sort all events from the individual DOOCS server by trainID. When requested [[HDF files>>doc:FLASHUSER.Information about the FLASH HDF5 structure]] are created after the beamtime which includes the important data from [[the accelerator and its diagnostic>>doc:FLASHUSER.PBD DAQ]] as well as the data created by the [[users>>doc:FLASHUSER.Description of the Properties in the FLASH1_USER1, 2 and 3 for FLASH1 Users]]. This time scale we define as {{code language="none"}}offline{{/code}} as the HDF files are converted after the beamtime is over. For synchronous data during an experiment it is possible to create shorter HDF slices via a {{code language="none"}}nearOnline{{/code}} converter within a few minutes. For working with this partially incomplete HDF slices we provide an API called [[BeamtimeDaqAccess>>doc:FLASHUSER.Beamtime DAQ Access]]. Reading synchronous data via an {{code language="none"}}online{{/code}} API is possible via a configurable DAQ middle layer server, the [[DAQmonitor>>doc:AIDA2020ESST.DAQ Monitor]], which feeds the correlated data back in the control system while it provides a ring buffer with 32 events in size.
