Method Detail

createTransformationSequence

public OraTransformationSequence createTransformationSequence(java.lang.String inputDataURI,
                                                              java.util.List listOfTransforms,
                                                              java.lang.String outputDataURI)
                                                       throws javax.datamining.JDMException

Creates the transormation sequence object, where user can specify the sequence of transformation operations that are to be performed. For example, to perform outlier treatment using clipping transform first and then normalize transform to bring the input data to the same scale, instead of doing them as a separate tasks, one can combine them into single transformation sequence (new named object in 11.1) and perform a single task that can accomplish the desired functionality.

In addition to OJDM defined tranformations, one can combine the expression transformations using OraExpressionTransform.

Note that text transformation cannot be combined in the sequence and it must be executed as a stand-alone transformation.

Parameters:

inputDataURI - input data used for the transformation

listOfTransforms - list of transformations

outputDataURI - ouput data URI

Returns:

Throws:

javax.datamining.JDMException
