public class DataSet

extends oracle.odi.domain.support.AbstractRepositoryEntity

implements IInterfaceSubComponent, OdiInterface.IPersistenceComparable<DataSet>

This class represents a dataset inside an OdiInterface. A DataSet is a subset of sources that can be combined with other DataSets using Set operators (such as UNION, MINUS, etc.). DataSets contain SourceDataStores, Joins, Filters and TargetMappings (which are occurrences of mappings executed on Source or Staging Area.
Note that this class is provided in read-only mode.
To make any modification to a DataSet please use instances of IInteractiveInterfaceHelper such as InteractiveInterfaceHelperWithActions.
