Glossary
- activity
-
a process element that associates executable logic
with an event such as a status change or timer event.
- activity status
-
the outcome of an activity in a process. The
status of an activity (for example, Started, Canceled, Accepted) is
typically used to trigger the next activity.
- candidate model
-
a predictive model that evaluates a model's predictive
power as compared with the champion model's predictive power.
- challenger model
-
a model that is compared and assessed against
a champion model for the purpose of replacing the champion model in
a production scoring environment.
- champion model
-
the best predictive model that is chosen from
a pool of candidate models in a data mining environment.
- channel
-
a virtual communication path for distributing
information. In SAS, a channel is identified with a particular topic.
Using the features of the Publishing Framework, authorized users or
applications can publish digital content to the channel, and authorized
users and applications can subscribe to the channel in order to receive
the content.
- classification model
-
a predictive model that has a categorical, ordinal,
or binary target.
- data object
-
an object that holds the business data that is
required to execute workflow process activities.
- data set
-
See SAS data set
- data source
-
a table, view, or file from which you will extract
information. Sources can be in any format that SAS can access, on
any supported hardware platform. The metadata for a source is typically
an input to a job.
- DATA step
-
in a SAS program, a group of statements that begins
with a DATA statement and that ends with either a RUN statement, another
DATA statement, a PROC statement, or the end of the job. The DATA
step enables you to read raw data or other SAS data sets and to create
SAS data sets.
- DATA step fragment
-
a block of SAS code that does not begin with a
DATA statement. In SAS Model Manager, all SAS Enterprise Miner models
use DATA step fragments in their score code.
- identity
-
See metadata identity
- input variable
-
a variable that is used in a data mining process
to predict the value of one or more target variables.
- instance
-
See process instance
- library reference
-
See libref
- libref
-
a SAS name that is associated with the location
of a SAS library. For example, in the name MYLIB.MYFILE, MYLIB is
the libref, and MYFILE is a file in the SAS library.
- metadata
-
descriptive data about data that is stored and
managed in a database, in order to facilitate access to captured and
archived data for further use.
- metadata identity
-
a metadata object that represents an individual
user or a group of users in a SAS metadata environment. Each individual
and group that accesses secured resources on a SAS Metadata Server
should have a unique metadata identity within that server.
- milestone
-
a collection of tasks that complete a significant
event. The significant event can occur either in the process of selecting
a champion model, or in the process of monitoring a champion model
that is in a production environment.
- model function
-
the type of statistical model, such as classification,
prediction, or segmentation.
- model scoring
-
the process of applying a model to new data in
order to compute outputs.
- output variable
-
in a data mining process, a variable that is computed
from the input variables as a prediction of the value of a target
variable.
- package
-
See SAS package file
- package file
-
See SAS package file
- participant
-
a user, group, or role that is assigned to an
activity. These users, groups, and roles are defined in SAS metadata
and are mapped to standard roles for the process.
- policy
-
a process element that associates executable logic
with an event such as a status change or timer event.
- prediction model
-
a model that predicts the outcome of an interval
target.
- process
-
a series of activities, together with the participants
and the logic that is required to execute the activities. A workflow
process includes policies, status values, and data objects.
- process definition
-
a process template that has been uploaded to the
server and activated. Process definitions are used by the SAS Workflow
Engine to create new workflow process instances.
- process instance
-
a process that is running in the SAS Workflow
Engine. After a process template is uploaded to the server and activated,
client applications can use the template to create and run a new copy
of the process definition. Each new copy is a process instance.
- process template
-
a model of a process that has been saved to an
XML file.
- project
-
a collection of models, SAS programs, data tables,
scoring tasks, life cycle data, and reporting documents.
- project tree
-
a hierarchical structure made up of folders and
nodes that are related to a single folder or node one level above
it and to zero, one, or more folders or nodes one level below it.
- publication channel
-
an information repository that has been established
using the SAS Publishing Framework and that can be used to publish
information to users and applications.
- publish
-
to deliver electronic information, such as files
and system-generated events, to one or more destinations. These destinations
can include e-mail addresses, message queues, publication channels
and subscribers, WebDAV-compliant servers, and archive locations.
- Publishing Framework
-
a component of SAS Integration Technologies that
enables both users and applications to publish SAS files (including
data sets, catalogs, and database views), other digital content, and
system- generated events to a variety of destinations. The Publishing
Framework also provides tools that enable both users and applications
to receive and process published information.
- SAS Content Server
-
a server that stores digital content (such as
documents, reports, and images) that is created and used by SAS client
applications. To interact with the server, clients use WebDAV-based
protocols for access, versioning, collaboration, security, and searching.
- SAS data set
-
a file whose contents are in one of the native
SAS file formats. There are two types of SAS data sets: SAS data files
and SAS data views.
- SAS Metadata Repository
-
a container for metadata that is managed by the
SAS Metadata Server.
- SAS Metadata Server
-
a multi-user server that enables users to read
metadata from or write metadata to one or more SAS Metadata Repositories.
- SAS package file
-
a container for data that has been generated or
collected for delivery to consumers by the SAS Publishing Framework.
Packages can contain SAS files, binary files, HTML files, URLs, text
files, viewer files, and metadata.
- SAS publication channel
-
See publication channel
- SAS variable
-
a column in a SAS data set or in a SAS data view.
The data values for each variable describe a single characteristic
for all observations (rows).
- scoring
-
See model scoring
- scoring function
-
a user-defined function that is created by the
SAS Scoring Accelerator from a scoring model and that is deployed
inside the database.
- scoring task
-
a process that executes a model's score code.
- segmentation model
-
a model that identifies and forms segments, or
clusters, of individual observations that are associated with an
attribute of interest.
- source
-
See data source
- SPK
-
See SAS package file
- subscriber
-
a recipient of information that is published to
a SAS publication channel.
- variable
-
See SAS variable
- version folder
-
a folder in the Project Tree that typically represents
a time phase and that contains models, scoring tasks, life cycle data,
reports, documents, resources, and model performance output.
- WebDAV server
-
an HTTP server that supports the collaborative
authoring of documents that are located on the server. The server
supports the locking of documents, so that multiple authors cannot
make changes to a document at the same time. It also associates metadata
with documents in order to facilitate searching. The SAS business
intelligence applications use this type of server primarily as a report
repository. Common WebDAV servers include the Apache HTTP Server (with
its WebDAV modules enabled), Xythos Software's WebFile Server, and
Microsoft Corporation's Internet Information Server (IIS).
- workflow
-
a sequence of processes together with the people,
information and tools that are necessary to accomplish a specific
business objective or goal.
