Remarks

This class inherits from the DataSet class to define the tables and relations which represent how the DICOM information is stored and retrieved.

The DicomInformation class contains four strongly typed tables:

Each DataTable is related to another table with a foreign key relationship.

The DicomInformation.StudiesDataTable has a foreign key relation with the DicomInformation.PatientsDataTable using the DicomInformation.StudiesDataTable.PatientIDColumn column.

The DicomInformation.SeriesDataTable has a foreign key relation with the DicomInformation.StudiesDataTable using the DicomInformation.SeriesDataTable.StudyInstanceUIDColumn column.

The DicomInformation.ImagesDataTable has a foreign key relation with the DicomInformation.SeriesDataTable using the DicomInformation+ImagesDataTable.SeriesInstanceUIDColumn column.
