All Implemented Interfaces:

java.io.Serializable

public class NonTransactionalDataSpecification

extends PhysicalDataSpecification

A NonTransactionalDataSpecification instance instructs the DMS to treat associated data as "non-transactional", that is, the data consists of one record (row) per case. To support text mining a new data-member called "Sequence Attribute" is added to this class. For datasets which has text attribute, must define a sequence attribute (a.k.a case id), to uniquely identify a record.

Since:

9.0.1

Constructor Summary

NonTransactionalDataSpecification()
Deprecated. As of 9.2.0, replaced by NonTransactionalDataSpecification(LocationAccessData)

NonTransactionalDataSpecification(LocationAccessData lad)
Creates a NonTransactionalDataSpecification instance with the specified location access data.

Method Summary

Attribute	getSequenceAttribute() Returns sequence attribute, if there is no sequence attribute defined then it returns null.
static NonTransactionalDataSpecification	restore(Connection dmsConn, java.lang.String pdsName) Restores the user-specified NonTransactionalDataSpecification object from the DMS.
void	setSequenceAttribute(Attribute sequenceAttr) Sets the sequence attribute for the non-transactional data with text attribute.
