Sample Transformation Welcome Page

The Sample Transformation wizard creates a random sample of a table or view; the generated random sample can be either a table or a view. You can specify the sample size either as a number of records or as a percentage of records. You can also specify a random seed.

A random sample is created by choosing a sample of cases picked at random. The random sample is smaller than the set that it is based on. Using the smaller sample can result in improved performance. If the sample is representative of the whole set, results generated using the sample will be compatible with the results generated using the whole set.

Oracle Data Miner also supports the Stratified Sample Wizard; stratified sampling is described in How to Use Stratified Sampling.

The output of the wizard is described in Output.

After the wizard creates the new table or view, it adds the table or view to the Navigator tree and displays the new table or view.
