We’re announcing a new release of Oracle Cloud Infrastructure (OCI) Data Catalog. This release introduces many improvements, such as a new overview page, a way to reorganize the business glossary, and event notifications for customer property changes in the catalog.

OCI Data Catalog is a metadata management service that helps data professionals discover data and support data governance in Oracle Cloud and beyond. It provides a searchable inventory of assets with business context and a unified metastore for you: the lake house. For more information on this topic, check out What is a Data Catalog?

New overview page

A new landing page for the OCI Data Catalog service gives new users an overview of the benefits of the service, its core capabilities, and available resources to get started with data catalog. Returning users can navigate to any existing data catalog, metastore, and private endpoint. You also get useful shortcuts to documentation, video tours, blogs, and news about recent releases.

Easily reorganize your glossary

OCI Data Catalog allows you to create a business glossary to capture your organization’s business vocabulary. This capability helps establish a common language among data users and helps them better understand data associated with business terms. Terms and categories are displayed in alphabetical order in a tree navigation list, allowing you to browse the glossary more efficiently.

Glossaries can contain many terms and categories. As business needs change, you might need to change the hierarchy of categories and terms. OCI Data Catalog now allows you to move terms and categories within the glossary making it easier for you to rearrange them. You can move a single term or category with an easy drag-and-drop action. To move multiple terms and subcategories within a category, you can use the Move action button, and the overlay dialog guides you through the process. These operations are available through REST APIs too. Moving the terms and categories doesn’t impact links to technical objects in the catalog.

Act on updates to catalog objects

Custom properties allow users to define their own properties for specific metadata enrichment needs. Custom properties are associated with data catalog object types and allow you to curate details at the object level. If you want to get notified when the value of a custom property changes for an object, you can now configure OCI Data Catalog to emit events on such updates. You have the flexibility to generate events only for a subset of object types associated with the custom property. Suppose you have a custom property called Certified and want to be notified when the value of the custom property changes for the Table data entity type. You can enable events for only that example, as shown in the following screenshot.

Events are generated in the form of a JSON file when a value is set, modified, or deleted for the custom property of an associated object. You can set up the OCI Events service to send you this JSON file in an email or through Slack. For bulk curation operations with the export and import custom properties features, events aren’t generated to avoid a large number of unnecessary messages.

Oracle Analytics Cloud (OAC) Beta Program

A beta preview of Data Catalog integration with Oracle Analytics has been extended until end of 2021. Customers can self-nominate for Oracle Analytics beta preview on OCI Console Beta Preview.

Other enhancements

In this release, you also have the following capabilities:

  • Securely store your data asset connection details, such as wallets and passwords, in Oracle Vault and use the vault secret OCIDs to configure connections.

  • Harvest metadata from Oracle MySQL Database service.

  • Sort by position or name in lists for entities and attributes in RDBMS data assets.


With this release, you can easily reorganize the glossary as your organizational vocabulary evolves, react to changes in enrichments of catalog objects, and bring in harvested properties from new sources.

Organizations are embarking on their next-generation analytics journey with data lake houses, data lakes, autonomous databases, advanced analytics, artificial intelligence, and machine learning in the cloud. Data Catalog helps support discovery, insights, and governance of data assets. The current capabilities of Oracle Cloud Infrastructure Data Catalog are available to Oracle Cloud customers at no extra cost allowing them to start gaining more value from their data for better business outcomes. Try it out today!
