Below is the detailed description about newly added features in Datastage v9.1:

1. InfoSphere Information Server for Data Integration

•    InfoSphere Data Click

InfoSphere Data Click helps users retrieve data and provision systems with agility. Users can offload individual tables or entire schemas to generate sandbox environments for personal or group development work. The simple interface enables users of any skill level to complete the data integration task. InfoSphere Data Click inherits the built-in data governance features of the InfoSphere Information Server platform.

InfoSphere Data Click generates both design and operational metadata to support data lineage and impact analysis. InfoSphere Data Click assets also support linkages to the business glossary so that users can establish trust in the sources of information that are used. Also, administrators can define policies that control the data integration activity so that users cannot exceed limits that are based on enterprise requirements.

InfoSphere Data Click is installed when you install InfoSphere Information Server for Data Integration. InfoSphere Data Click activities are governed from InfoSphere Blueprint Director. You install InfoSphere Data Click as a plug-in into InfoSphere Blueprint Director.

•   InfoSphere DataStage

Workload management

You can now use the workload management service in InfoSphere Information Server to allow the administrator to set system resource policies and prioritization of workload classes. The policies and workload classes control the execution of parallel and server jobs.

Web-based job runtime management

Administration and management of the operational environment is simplified by extending the Operations Console. Authorized users can now define the workload management policies, and can run, stop, and reset integration jobs within the projects that they administer.

Balanced optimization for Hadoop

Extending the HDFS features in Version 8.7, you can now use the Balanced Optimization features of InfoSphere DataStage to push sets of data integration processing and related data I/O into a Hadoop cluster. InfoSphere DataStage adds integration with Oozie workflows, as well as real-time integration with InfoSphere Streams.

Support for IBM Rational Team Concert™ as a source control system

You can now use Rational Team Concert as a source control system in IBM InfoSphere Information Server Manager.

XML design and performance optimization enhancements

InfoSphere DataStage 9.1 includes new features to help you work with the type of large XML schemas that are often seen in industry standards. You can use one new feature, the schema view, to narrow the scope of a large XSD to only the subset of the schema tree that you want to work with.

When you narrow the scope, you can focus on a particular business challenge and parse and compose XML documents more easily. Other new features include user-specified parallelization for greater performance, extended support for XSD typing, and usability and productivity improvements in XML job editing through schema search and mapping intelligence.

2.   InfoSphere Information Server for Data Quality

• InfoSphere Data Quality Console

InfoSphere Data Quality Console is a new unified, browser-based interface that you can use to monitor and track data quality exceptions that are generated by InfoSphere Information Server products and components. Exceptions are entities that are generated by a condition or event and that might require additional information or investigation. For example, records that do not meet the conditions of data rules in InfoSphere Information Analyzer might be considered exceptions. The following screen capture shows how you can view a subset of exception descriptors by specifying search criteria, which include search terms and attributes.

• InfoSphere Information Analyzer

Predefined rule definitions

A key challenge in assessing and monitoring information quality is starting the process to validate key business requirements. Instead of starting that process without assistance, you can start by using predefined data quality rule definitions.

New installations of this release include more than 100 predefined rule definitions for basic and common domains. Also included are more than 60 predefined rule definitions that are designed to validate standardized address data. Although the rule definitions are optimized for US data, they can be modified for any country or region.

The data domains that are represented include the following domains:

·         Personal identity, such as age, date of birth, and national identifier

·         Asset identity, such as IP address information

·         Financial

·         Orders and sales

·         Data classification, such as identifier, indicator, code, date, and quantity

·         Completeness, which checks whether a field exists

·         Data format, such as alphabetic and numeric

·         Address data

User-named output tables for data rules

When you create data rules, you can specify that you want a user-named rule output table to be created in addition to the system rule output tables. User-named output tables can be simple or advanced. Use a simple table if you plan to use the rule output from one rule to create subsequent rules. Use an advanced table if you want to collect rule output from multiple data rules into one table. Also, you might want to create an advanced user-named table if you plan to use the rule output from multiple rules to create subsequent rules. An advanced user-named table is an additional physical table with copied records, which means that it requires additional storage space.

Distinct output records

You can now specify whether you want only distinct output records or all output records in the rule output table.

Task sequencing

You can now use task sequences to group multiple InfoSphere Information Analyzer jobs that are to be executed sequentially. In this release, task sequencing is available only by using the HTTP API and CLI, and only rules, rule sets, and metrics are supported for task sequencing.

 

• InfoSphere QualityStage

Standardization Rules Designer

The new Standardization Rules Designer provides an intuitive and efficient framework that you can use to enhance standardization rule sets. You can use the browser-based interface to add or modify classifications, lookup tables, and rules.

You can also import sample data to validate that the enhancements to the rule set work with your data. The following screen capture shows a part of the Standardization Rules Designer in which you can add or modify a rule by mapping input values from an example record to output columns. This rule splits concatenated values in an input address record by mapping each part of the input value to a different output column.

New rule sets

The following rule sets are now available:

·   The PHPROD rule set is a rule set for pharmaceutical data. The rule set demonstrates how you can use rules to standardize description data from the health industry.

·     The RUNAMEL rule set can be used to standardize Russian names.

·    The RUADDRL rule set can be used to standardize Russian addresses and area information.

Rule set enhancements

The predefined rule sets are enhanced in the following ways:

·         The domain-specific rule sets can be used with the Standardization Rules Designer.

·       The CNNAME, HKCNAME, and HKNAME rule sets now have special options for name processing.

·      The CNADDR, CNAREA, CNPHONE, HKADDR, HKCADDR, and HKPHONE rule sets now have user modification subroutines.

·       The CNPHONE and HKPHONE rule sets are enhanced in several ways. For example, input data can be converted to half-width characters.

Sample data available for predefined jobs and tutorial

Sample data is now provided for the predefined standardization jobs that you can use to generate standardized data and the frequency information for that data.The installation media also now contains sample data and other files that are required for the InfoSphere QualityStagetutorial.

3.   InfoSphere Metadata Asset Manager

Enhanced documentation of import and export bridges

Individual reference topics for each bridge contain prerequisites, frequently asked questions, troubleshooting information, and detailed help for each parameter. Individual PDF guides to using BI bridges contain customized information for imports from IBM Cognos, SAP BusinessObjects, Microsoft, and Oracle BIEE.

Mapping documents for each import bridge show how each metadata class in the source tool is displayed inInfoSphere Information Server.

Asset interchange and istool command line

The following functions are documented:

·         Exporting and importing InfoSphere Streams assets.

·         Exporting and importing InfoSphere Data Quality Console assets

·      Generating business glossary content from InfoSphere Data Architect glossary        models

• Migrating

New migration functions

To help you to migrate automatically, you can now use two new migration wizards. The wizards automate the process of exporting and importing databases, profiles, and directories that are associated with InfoSphere Information Server. The wizards collect information about your computer and InfoSphere Information Server configuration. The information is then used to export and import your system.

The migration wizards support all three server tiers: the services tier, the engine tier, and the metadata repository tier. When you export or imports by using the wizards, all tiers that are installed on the computer are backed up simultaneously.

5.   InfoSphere Business Information Exchange

• InfoSphere Business Glossary

Expanded enterprise information governance policies and rules

Now, in addition to creating and managing terms and categories, you can create and manage information governance policies and information governance rules. Information governance policies and rules describe the way that information should be used and managed to comply with business objectives. You can define relationships among the policies and rules and between the policies and rules and other metadata information assets.

Advanced term relationships

You can use new relationships between terms to express hierarchies of type and containment. The relationships enable consumers of the information to understand the meaning of terminology more fully, in the context of other terms.

Single sign-on for Windows users

Integration with Windows desktop authentication enables users who are logged in to Windows to work with InfoSphere Business Glossary immediately, without requiring a separate login process.

Web-based access to blueprints

You can now define information about blueprints and view published blueprints directly from the business glossary.

Dynamic display of external content from OSLC providers

OSLC (Open Services for Lifecycle Collaboration) is a method of communicating among different systems. InfoSphere Business Glossary can now be a consumer of OSLC services from Rational Asset Manager and Rational Software Architect Data Manager.

The metadata content that is stored in these OSLC providers is displayed dynamically in the business glossary. The dynamic display ensures that data is synchronized and eliminates the need for separate data transfer procedures.

Enhanced integration with InfoSphere Information Analyzer

In previous releases, you were able to view the results of table and column analysis, including valid values for columns. You can now browse, search, view details of, and assign published data rule definitions and data rule set definitions to business glossary assets.

• InfoSphere Business Glossary Client for Eclipse

Information governance policy and information governance rule assets

You can now browse, search, and display the properties of two new InfoSphere Business Glossary assets: information governance policies and information governance rules. You can assign an information governance rule to an asset, such as a database table, so that the information governance rule governs the asset.

Import and export of glossary assignments

Earlier versions supported import and export term assignments. In version 9.1, you can import and export glossary assignments, which include both, term assignments and information governance rule assignments.

Advanced term relationships from InfoSphere Business Glossary

Two new term relationships, Is A and Has A, are included in the Properties view of a term. You can view the supertype and subtype relationship between terms in the Term Type Hierarchy view.

Business Process Modeling Notation (BPMN) model elements

You can now view and remove term assignments in BPMN model elements that are displayed in IBM Rational Software Architect. With the Business Process Model Integration API, you can build functions to add, remove, and get term assignments to BPMN model elements.
