A.2.3 Key integration functions
We describe the key integration functions shown in Figure A-1 on page 527
briefly here:
򐂰 Understand your data
IBM Information Server helps you to discover, define, and model information
content and structure automatically and to understand and analyze the
meaning, relationships, and lineage of information. By automating data
profiling and data-quality auditing within systems, organizations can achieve
the following goals:
Understand data sources and relationships
Eliminate the risk of using or proliferating bad data
Improve productivity through automation
Take advantage of existing IT investments
IBM Information Server makes it easier for businesses to collaborate across
roles. Data analysts can use analysis and reporting functionality, generating
integration specifications and business rules that they can monitor over time.
Subject matter experts can use Web-based tools to define, annotate, and
report on fields of business data. A common metadata foundation makes it
easier for different types of users to create and manage metadata by using
tools that are optimized for their roles.
The upcoming WebSphere Information Analyzer product module will provide
this functionality.
򐂰 Cleanse your information
IBM Information Server supports information quality and consistency by
standardizing, validating, matching, and merging data. It can certify and
enrich common data elements, use trusted data such as postal records for
name and address information, and match records across or within data
sources. IBM Information Server allows a single record to survive from the
best information across sources for each unique entity, helping you to create a
single, comprehensive, and accurate view of information across source
systems.
The WebSphere QualityStage product module currently provides this
functionality.
򐂰 Transform your data into information and move
IBM Information Server transforms and enriches information to ensure that it
is in the proper context for new uses. Hundreds of prebuilt transformation
functions combine, restructure, and aggregate information.
Transformation functionality is broad and flexible to meet the requirements of
varied integration scenarios. For example, IBM Information Server provides
