524 IBM WebSphere Information Analyzer and Data Quality Assessment
Over the years, most organizations have made significant investments in
enterprise resource planning, customer relationship management, and supply
chain management packages in addition to their home grown applications. These
packages have resulted in larger amounts of data being captured about their
businesses. To turn all this data into consistent, timely, and accurate information
for decision-making requires an effective means of integrating information.
Statutory compliance requirements, such as Basel II and Sarbanes-Oxley, place
additional demands for consistent, complete, and trustworthy information.
IBM Information Server addresses these critical information integration
requirements of consistent, complete, and trustworthy information with a
comprehensive, unified foundation for enterprise information architectures,
capable of scaling to meet any information volume requirement so that
companies can deliver business results faster and with higher quality results for
all the following initiatives:
IBM Information Server makes it easier to develop a unified view of the
business for better decisions. It helps you understand existing data sources,
cleanse, correct, and standardize information, and load analytical views that
can be reused throughout the enterprise.
Master data management
IBM Information Server simplifies the development of authoritative master
data by showing where and how information is stored across source systems.
It also consolidates disparate data into a single, reliable record, cleanses and
standardizes information, removes duplicates, and links records together
across systems. This master record can be loaded into operational data
stores, data warehouses, or master data applications such as WebSphere
Customer Center and WebSphere Product Center. The record can also be
assembled, completely or partially, on demand.
IBM Information Server aids in reducing operating costs by showing
relationships between systems and by defining migration rules to consolidate
instances or move data from obsolete systems. Data cleansing and matching
ensure high-quality data in the new system.
IBM Information Server can speed development and increase business agility
by providing reusable information services that can be plugged into
applications, business processes, and portals. These standards-based

information services are maintained centrally by information specialists but
are widely accessible throughout the enterprise.
Risk and compliance
IBM Information Server helps improve visibility and data governance by
enabling complete, authoritative views of information with proof of lineage and
quality. These views can be made widely available and reusable as shared
services, while the rules inherent in them are maintained centrally.
IBM Information Server combines the technologies of key information integration
functions within the IBM Information Integration Solutions portfolio into a single
unified platform that enables companies to understand, cleanse, transform,
move, and deliver trustworthy and context-rich information as shown in
Figure A-1 on page 527.
IBM Information Server includes the following product modules:
IBM WebSphere DataStage
It enables organizations to design data flows that extract information from
multiple source systems, transform it in ways that make it more valuable, and
then deliver it to one or more target databases or applications.
IBM WebSphere QualityStage
Designed to help organizations understand and improve the overall quality of
their data assets, WebSphere QualityStage provides advanced features to
help investigate, repair, consolidate, and validate heterogeneous data within
an integration workflow.
IBM WebSphere Federation Server
It enables applications to access and integrate diverse data and content
sources as though they were a single resource—regardless of where the
information resides—while retaining the autonomy and integrity of the
heterogeneous data and content sources. This enabling technology is
transparent, heterogeneous, and extensible, and provides high function and
IBM WebSphere Information Services Director
IBM Information Server provides a unified mechanism for publishing and
managing shared service-oriented architecture (SOA) services across data
quality, data transformation, and federation functions, allowing information
specialists to easily deploy services for any information integration task and
consistently manage them. This enables developers to take data integration
logic built using IBM Information Server and publish it as an
service—in minutes. The common services also include the metadata
services, which provide standard service-oriented access and analysis of
metadata across the platform.
