Storing and deploying repository objects

Streams created in IBM® SPSS® Modeler can be stored in the repository just as they are, as files with the extension .str. In this way, a single stream can be accessed by multiple users throughout the enterprise. See the topic Storing Objects in the Repository for more information.

It is also possible to deploy a stream in the repository. A deployed stream is stored as a file with additional metadata. A deployed stream can take full advantage of the enterprise-level features of IBM SPSS Collaboration and Deployment Services, such as automated scoring and model refresh. For example, a model can be automatically updated at regularly-scheduled intervals as new data becomes available. Alternatively, a set of streams can be deployed for Champion Challenger analysis, in which streams are compared to determine which one contains the most effective predictive model.

Note: The Association Rules, STP, and TCM modeling nodes do not support the Model Evaluation or Champion Challenger steps in IBM SPSS Collaboration and Deployment Services.

You can deploy a stream (with the extension .str). Deployment as a stream enables the stream to be used by the thin-client application IBM SPSS Modeler Advantage. See the topic Opening a Stream in IBM SPSS Modeler Advantage for more information.

For more information, see Stream Deployment Options.

Other Deployment Options

While IBM SPSS Collaboration and Deployment Services offers the most extensive features for managing enterprise content, a number of other mechanisms for deploying or exporting streams are also available, including:

  • Export the stream and model for later use with IBM SPSS Modeler Solution Publisher Runtime.
  • Export one or more models in PMML, an XML-based format for encoding model information. See the topic Importing and exporting models as PMML for more information.
