Setting up reporting for Watson Knowledge Catalog

Configure reporting to query metadata from Watson Knowledge Catalog and generate dashboards and reports by using BI tools such as Cognos Analytics and Tableau. The insights allow your data and governance teams to make use of data analytics, identify data issues, and efficiently allocate resources.

To create a report, use an SQL query to pull the data to a supported external relational database of your choice. Then, connect to a reporting tool like Cognos Analytics to generate reports, see Sample reporting queries for Watson Knowledge Catalog.

To ensure that sensitive data is protected, you can send data to various schemas on the database, and restrict access to these schemas.

Only top-level categories can be enabled for reporting. Subcategories use the same schema as their top-level categories.

Types of data you can query and report

You can create reports on many types of metadata if you have the required permissions:

Catalogs

Catalog and asset metadata information (for example, tags and description)
Asset to asset relationship (for example, child-parent relationship)
Asset to governance artifact relationship
Data quality rules (for example, definition, binding, and execution)
Data quality checks (for example, asset and column problems)
Asset to a governance artifact or category custom relationship (for example, a custom property to business term relationship)

Projects

Metadata imports
Metadata enrichments (for example, artifact assignment)
Asset to asset relationship
Asset to governance artifact relationship
Data quality rules (for example, definition, binding, and execution)
Data quality checks (for example, asset and column problems)

Governance artifacts

Custom properties in governance artifacts
Custom category roles
Metadata of category with custom role
Metadata of all the governance artifacts (for example, business terms)
Associations between all governance artifacts
Associations between data protection rules and governance artifacts

Admin

User profiles (for example, user and display names)
Workflows for governance artifacts (for example, workflow for creating a business term)

Requirements

Supported database types

Oracle
Db2 version 11.5, and later
Db2 on Cloud with a Standard or Enterprise plan

If you select a Db2 database for storing the reports, make sure to create the database with 32 K page size.

db2 create database <DATABASE_NAME> PAGESIZE 32 K

PostgreSQL version 12, and later

Prerequisites

You need a nonvaulted connection to a supported type of database. If no connection is defined in the platform connections, contact your administrator to configure at least one. See Connecting to data sources at the platform level.

Required permissions

To configure the reporting, you must have the following user role:

Reporting Administrator

For custom user roles, use the following permissions to access the Report Setup:

Manage reporting
Monitor project workloads
Manage catalogs

Procedure to set up and configure reports

When you configure reporting you select where to send the Watson Knowledge Catalog data and what data to use for reporting.

To set up the reporting:

Go to Administration > Governance and catalogs > Report setup.
Select a connection to a database. If no connection is defined, see Prerequisites.
Select the default schema. All data is written to the selected schema by default, but you can edit the schema for a particular catalog, project, or category. Make sure that the database users have write access to the selected schemas.
Enable the catalogs, projects, categories, or data protection rules for which you want to run the reports.
Click Save settings.

Next steps

Before you start reporting you can modify the settings. For example, you can change the schema that you use, enable and disable data for reporting by using the slidebar for each concrete type of data. After you save the new settings and update the reporting, the reports are updated. For more information, see Managing reporting for Watson Knowledge Catalog.

To better understand the relationships between the SQL tables that store the reporting data, see Data model for Watson Knowledge Catalog reporting.
