Data File Tables

Depending on parameter values specified for data file and data file group id during batch data deletion, data from the source table may be deleted and therefore audited.

• If you specify a data file, the corresponding record in DATA_FILES is deleted.
• If you specify a data file group and no data file, the corresponding record in DATA_FILE_GROUPS and related records in DATA_FILES is deleted.
• If you accept all default parameters, all records for the study in DATA_FILE_GROUPS and DATA_FILES are deleted.

The DATA _FILES table stores names of files used to do a batch data load.

The DATA_FILE_GROUPS stores group of files that are submitted together.
