Information Steward architecture for quick reference

BI platform or
IPS component

Usage for Data Services

Usage for Information Steward

Web Tier

Deploys Data Services on the Central
Management Console (CMC) through
which administrative tasks for Data Services
are performed.

Deploys Information Steward on:
• The CMC through which administrative
tasks for Information Steward are
performed.
• A web application server through
which you access the Information
Steward modules

Central Management
Console
(CMC)

Used by IT administrator to manage:
• SAP solutions for Enterprise Information
Management (EIM) Adaptive
Processing Server and services
• User security (authentication and authorization)
• Repository and application settings

Used by IT administrator to manage:
• EIM Adaptive Processing Server and
services
• Information Steward Job Server and
services
• Metadata Management module
• Data Insight module
• Cleansing Package Builder module
• Data Review module connections and
tasks
• Information Steward utilities
• User security (authentication and authorization)
• Repository and application settings

Central Management
Server
(CMS)

Maintains a database of information
about your SAP BusinessObjects BI
platform system. The data stored by the
CMS includes information about users
and groups, security levels, schedule information,
BI platform content, and
servers.
For more information about the CMS,
see the SAP BusinessObjects Business
Intelligence Platform Administrator’s
Guide. If you installed IPS, see the SAP
BusinessObjects Information platform
services Administrator’s Guide.
Data Services relies on the CMS for:
• Centralized user and group management
• Flexible authentication methods
• Password enforcement policies

Maintains a database of information
about your BI platform system. The data
stored by the CMS includes information
about users and groups, security levels,
schedule information, BI platform content,
and servers.
The following objects in the Metadata
Management module of Information
Steward are stored in the CMS.
• Integrator Source configurations
• Source groups
• Utilities configurations
• Data Insight connections
• Projects
• Tasks
Note:
Because integrator source configurations
and source group definitions are stored
in the CMS, you can use the Upgrade
management tool to move them from one
version of the CMS to another. The
schedules and rights information are
considered dependencies of these configurations.
For details, see the SAP
BusinessObjects Information Steward
Upgrade Guide.

Platform
Scheduling
Services

The Platform Scheduling Services is not
required to run Data Services. If you will
not install Information Steward, you can
stop the Platform Scheduling Services.

Information Steward Job Server uses the
Platform Scheduling Services for executing
profiling tasks and integrator tasks.
The server may host the following services
for Information Steward:
• Task Scheduling Service
• Integrator Scheduling Service
• Data Review Scheduling Service

Platform Processing
Services

Required during Data Services installation
to create the Enterprise Information
Management (EIM) Adaptive Processing
Server .
The EIM Adaptive Processing Server
uses the Platform Processing Services
to host the following services:
• RFC Server Service, which Data
Services requires for connectivity with
SAP NetWeaver Business Warehouse
• Job Launcher Service, which Data
Services uses to send batch jobs to
the appropriate Data Services Job
Server for execution.
• Data Services Metadata Browsing
Service, which is used by other applications
such as Information Steward
to browse and import metadata from
Data Insight connections
• Data Services View Data Service,
which is used by other applications
such as Information Steward to view
data in Data Insight connections
The Data Services Workbench requires
the Enterprise Information Management
Adaptive Processing Server for operations
such as testing connections and all
communication with the repository to
deploy object, run jobs, and so forth.
The Platform Processing Service can be
stopped after installation because on the
Enterprise Information Management
Adaptive Processing Server is required
for Data Services to run.

Required during Information Steward
installation to create the Enterprise Information
Management Adaptive Processing
Server .
The EIM Adaptive Processing Server
uses the Platform Processing Services
to host the following services:
• Metadata Search Service
• Metadata Integrator Service
• Data Services Metadata Browsing
Service
• Data Services View Data Service
• Information Steward Administrator
Task Service
• Cleansing Package Builder Core
Service
• Cleansing Package Builder Autoanalysis
Service

stored information can be accessed
by Data Services

Stores files associated with:
• A published cleansing package. The
stored information can be accessed
by Data Services
• History logs for Data Insight task and
