Store (RapidMiner Studio Core)

Synopsis

This operator stores an IO Object in the data repository.

Description

This operator stores an IO Object at a location in the data repository. The location of the object to be stored is specified through the repository entry parameter. The stored object can be used by other processes by using the Retrieve operator. Please see the attached Example Processes to understand the basic working of this operator. The Store operator is used to store an ExampleSet and a model in the Example Processes.

Input

input
This port expects an IO Object. In the attached Example Processes an ExampleSet and a model are provided as input.

Output

through
The IO Object provided at the input port is delivered through this output port without any modifications.This is usually used to reuse the same IO Object in further operators of the process.

Parameters

repository_entryThis parameter is used to specify the location where the input IO Object is to be stored. Range: string

Tutorial Processes

Storing an ExampleSet using the Store operator

This Process shows how the Store operator can be used to store an ExampleSet. The 'Golf' data set and the 'Golf-Testset' data set are loaded using the Retrieve operator. These ExampleSets are merged using the Append operator. The resultant ExampleSet is named 'Golf-Complete' and stored using the Store operator. The stored ExampleSet is used in the third Example Process.

Storing a model using the Store operator

This Process shows how the Store operator can be used to store a model. The 'Golf' data set is loaded using the Retrieve operator. The Naive Bayes operator is applied on it and the resultant model is stored in the repository using the Store operator. The model is stored with the name 'Golf-Naive-Model'. The stored model is used in the third Example Process.

Using the objects stored by the Store operator

This Process shows how a stored IO Object can be used. The 'Golf-Complete' data set stored in the first Example Process and the 'Golf-Naive-Model' stored in the second Example Process is loaded using the Retrieve operator. The Apply Model operator is used to apply the 'Golf-Naive-Model' on the 'Golf-Complete' data set. The resultant labeled ExampleSet can be viewed in the Results Workspace.
