Using IBM SPSS Modeler with a Repository
Figure 9-1
Objects in the IBM SPSS Collaboration and Deployment Services Repository
Extensive Versioning and Search Support
The repository provides comprehensive object versioning and search capabilities. For example,
suppose that you create a stream and store it in the repository where it can be shared with
researchers from other divisions. If you later upd ate the stream in SPSS Modeler, you can add
the updated version to the repository without overwriting the previous version. All versions
remain accessible and can be searched by name, label, fields used, or other attributes. Youcould,
for example, search for all model versions that use net revenue as an input, or all models created
by a particular author. (To do this with a traditional file system, you would have to save each
version under a different filename, and the relationships between versions would be unk nown
to the software.)
Single Sign-On
The single sign-on feature enables users to connect to the repository without having to enter
username and password details each time. The user ’sexisting local netw ork login details provide
the necessary authentication to IBM SPSS Collaboration and Deployment Services. This feature
depends on the following:
IBM SPSS Collaboration and Deployment Services must be configured to use a sin gle sign-on
provider.
The user must be logged in to a host that is compatible with the provider.
