Default View Creation Algorithm

Data extract is always done at the study level, either within a single study or across multiple studies. You can perform data extract for all DCMs, though it is not done for all the DCMs by default. For View Builder-enabled studies, you can default the View Definitions from DCMs. You can perform this default when the DCM is activated, or on an ad-hoc basis by choosing Default View Definition from the Special menu.

Data extract views are created as follows:

For every DCM, one view is created to contain the data for all non-repeating DCM question groups in the DCM. The name of the data extract view is the DCM short name. For each repeating question group in a DCM, a view is created whose name is the DCM short name plus the DCM question group short name.

For example: in the study ORACLIN, a DCM called ET, with the short name ET, has three DCM question groups: SD_DOSAGE, TREADMILL_INFO, AND EXERCISE_STAGE, with the short names SD, TI, and ES, respectively. SD_DOSAGE and TREADMILL_INFO are non-repeating question groups, while EXERCISE_STAGE is repeating. These views are created for this DCM:

  • ET: Contains the data for the two non-repeating question groups, SD_DOSAGE and TREADMILL_INFO.

  • ETES: Contains the data for the repeating question group, EXERCISE_STAGE.

If a third non-repeating question group is added to this DCM, the data is included in the existing ET view; but if another repeating group is added to the DCM, another view is created.
