Latest information:

General

New in 11.7.1 Fix Pack 1

  • The Information Server Web (Administration) Console was replaced with a new implementation that contains the following functionality:
    • User and group management
    • Domain management
    • Session management
    • Limited reporting functionality through the user interface
    • Schedule monitoring functionality through the API
  • Microservices tier:
    • Authentication and secure connections are now enabled by default for Kafka and Solr services that are running on the microservices tier. Also, write access to the Zookeeper service requires authentication and proper ACLs are enforced on Kafka and Solr znodes.
    • SELinux in enforcing mode is now supported.
    • The microservices tier installer no longer creates Kubernetes resource definition files on the disk. Any specific modifications to the Kubernetes cluster state should be done using the kubectl CLI commands, such as kubectl edit.
  • IBM InfoSphere Information Server, Version 11.7.1, Fix Pack 1 does not support upgrade if Watson Knowledge Catalog is installed. For more information, see Remove Watson Knowledge Catalog from an Information Server 11.7.1.0 installation.

Watson Knowledge Catalog

New in 11.7.1

  • Watson Knowledge Catalog is an extension to Information Governance Catalog that provides self-service access to data assets for knowledge workers who need to use those data assets to gain insights.

Information Governance Catalog New

New in 11.7.1 Service Pack 2
  • When you run a quick scan, the discovery jobs and the results are now available on the new tab 'Quick scan results'. When you review the results, you can edit term assignments for the discovered assets. Quick scan also supports external Hadoop for JDBC connector, and new data source for JDBC connector: Postgres.
  • Virtual column management is supported. Virtual columns combine data from multiple columns and are used in analysis.
  • Managing rule set definitions and rule sets is supported. They are used to capture how a record within a data source conforms to multiple data rules. Each time you run a rule set, the run record is saved and you can review the run history for each rule set.
  • You can import and export data rules, rule sets, data rule definitions, and rule set definitions with a file in the XML format.
  • You can set the validity benchmark for data rules and rule sets. It is used to identify a minimum level of acceptability for the data or a tolerance for some level of exceptions.
  • You can detect biases in your data when you run a data quality analysis. Bias occurs when one column influences another column in a way it shouldn't. Note: This is a technology preview and is not yet supported for use in production environments.
New in 11.7.1 Service Pack 1
  • Managing data rules is supported. You can create, update, and delete the rules. You can also run them, and work with the results, and the run history.
  • When you bind data to quality and data rules, you can use global variables and literals.
  • You can configure workspace settings globally for all workspaces and individually for each workspace.
  • You can edit data set details and analysis results.
  • When you run column analysis, you can select individual columns to analyze.
  • After you review analysis results for a data set, you can mark it as reviewed to let other users know.
  • You can run new types of analysis: relationship and overlap analysis. The results are displayed in the entity relationship diagram (ERD).
  • When you search for data sets to add to a workspace, you can display available catalog data sets in the hierarchical format.
  • Quick scan is officially supported. You can run it with new data set types: Hive, Oracle, and SQL Server, with JDBC connector. Additionally, when you assign terms, you can choose to enable a machine learning model to get more accurate results.
  • While you browse the list of available data connections, you can check what assets are included in the file-based connections. You can also preview the content of the files or add them to workspaces.
  • When you search for assets in the catalog, you can download the results to a CSV file.
  • Creating queries is available in Catalog > Queries. You are redirected to Information Governance Catalog classic.
  • New Quality tab is added with data quality-related features:
    • Managing data rule definitions is possible in Information Governance New UI. Data rule definitions are used to develop rule logic to analyze data. They consist of a condition and action, and can be bound to physical data in quality and data rules. You can create, edit, delete, copy, and publish data rule definitions in Information Governance New.
    • You can organize data rule definitions in folders.
    • Creating quality rules is supported.
    • Workspace and data sets views were added. You can add data sets to workspaces and create new workspaces. In each data set, you can review the detailed status of the quality of your data, and download this information in a CSV file.
    • You can run column, data quality, and primary key analysis in a data set view.
    • You can create SQL virtual tables to join data from various tables with the use of an SQL statement.
    • For each quality dimension, you can download the CSV file with assets that violate the dimension.

New in 11.7.1

  • When you search for assets and enter a keyword, the results are now sorted by the best match. The searched keyword is highlighted in the drop down list of results.
  • Integration of Information Governance Catalog with Watson Knowledge Catalog is supported. For details, see the offering plans.
  • New Quality tab is added with data quality-related features (Technical Preview only - Do not use without SP1)
  • Automation rules can be automatically created by the system. Based on common patterns in existing automation rules, new rules are suggested. After you review them, you can accept them and use them like the automation rules that you created yourself.
  • When you create a customization profile, you can now select tabs like Queries, Monitoring, and so on, and also asset actions to be available to selected users.
  • You can import glossary assets when workflow is enabled. You can choose to either ignore workflow and make the changes public immediately after the import, or apply workflow process to each change to a catalog.
  • When workflow is enabled, you can view asset changes history in the Activities panel. The panel also supports adding comments.
  • After you ran a discovery, you can discover selected assets again and choose to analyze all metadata, or only metadata that changed since the last analysis.
  • When you configure a discovery, apart from schemas, you can also choose database tables as the discovery root.
  • Usability was enhanced, currently you can search for assets in one place in the Catalog tab. It's no longer possible to search for assets from the home page. It is easier to access relationship graph, it's available in the asset details page and in the search results list.
  • In the asset details page, you can display data in a tabular format.
  • You can run a quick scan to quickly analyze data in large data sets. Quick scan is much faster than the traditional discovery, because metadata is not imported. The first 1000 rows of each data set are analyzed. Note: This is a technology preview and is not yet supported for use in production environments.
InfoSphere Information Governance Catalog classic

You can apply the filter globally for all projects or for selected projects only.

New in 11.7.1

  • When in data rule definition logic you use 'matches data class' check, you can refer to both predefined and custom data classes.
  • When configuring automatic term assignment, you can use a new parameter algorithm for the linguistic name matching service. This parameter defines a list of settings which are used by the service. You can choose to ignore vowels in terms during matching and control the usage of the existing parameters replacements and WordsToIgnore. Additionally, the  machine learning service supports more languages, for example Chinese, however, the pre-processing is limited.

IBM DataStage Flow Designer

New in 11.7.1 Fix Pack 1

  • You can use a new job generation feature that automates and simplifies data movement, taking data from a source X and moving it to a target Y. Rather than having to craft a job to move this data by using the DataStage Edition canvas and palette, and then dragging connectors and stages to build a job, you can use the new job template to follow a simple series of steps and generate a parallel job. You can then use this parallel job to move the data. Also, if you are an administrator you can define target rule sets that define best practices and have users apply those to their job templates and eventual generated jobs.
  • You can define and edit column metadata. For example, for a column you can specify what delimiter character should separate text strings or you can set null field values. With the ability to edit column metadata you get more fine-tuned processing of your jobs and more useful data transformation.
  • You can create a container that has its own job flow and share and use it in other jobs.
  • New stages:
    • Complex flat file
    • Slowly changing dimension
  • New connector:
    • You can use the z/OS file connector.
    • You can use the SAP OData connector.
  • You can use the following steps in the Hierarchical stage:
    • JSON composer step
    • JSON parser step
    • REST step
    • Test assembly
    • Details inspector
    • Create/view contract libraries
    • Administration
  • Transformer stage support for tabs such as build, surrogate key, and triggers.
