---+ Work Flow

When a data taking run is over(typically 8 hours):

Bulk rec uses majority of tier0 resources.
   * AOD: Analysis Object Data, physics output like electrons, muons, tracks, etc.
   * HIST: Histograms for monitoring.
   * ESD: Event Summary Data, contained detailed reconstruction output like calorimeter cells and tracking hits (not produced for physics_main)
   * DRAW/DESD: for selected events.

Calibration Loop over express stream:
   * Histograms to monitor.
   * Alignment work of inner tracker can be done.
   * The beamspot is determined (with new alignment).
Calibration loop (48hrs)

Defects and GRL: take Muon DQ as an example: [[RongkunMuonOfflineDataQualityTutorial][MyMuonDQTutorial]]. Good quality of data, 'quality' measured by subdetector performance.

---++ Data Streams

Different data stream, coming from different trigger chain, for different purpose
   * Express stream
   * Physics_main
   * B physics stream
   * [[RongkunTrigger#Zero_bias][Zero Bias]]
   * [[RongkunTrigger#Minimum_bias][Min-Bias]] , etc..
