Using IBM SPSS Modeler with a Repository

Objects in the IBM SPSS Collaboration and Deployment Services Repository

Extensive Versioning and Search Support

The repository pro vides comprehensive object versioning and searc h capa

bilities. For example,

suppose that you create a stream and store it in the rep ository where it can be shared with

researchers from othe r divisions. If you later update the stream in SPSS Modeler, you can add

the updated version to the repository w ithout overwriting the pr evious v

ersion. All versions

remain accessible and can be searched by name, label, ﬁelds used , or other attributes. You cou ld,

for example, search for all m odel versions that use net revenue a s an input, or all models created

by a particula r author. (To do this with a traditional ﬁle system, you woul

d have to save each

version under a different ﬁlename, and the relationships between versions would be unknown

to the s oftware.)

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’s existing local netw ork login details provide

the neces sary authentication t o IBM SPSS Collaboration and Deployment Services. This feature

depends on the following:

 IBM SPSS Collaboration and Deployment Services must be conﬁgured to use a single sign-on

provider.

 The user must be logged in to a host that is compatible with the provider.
