Talend Data Catalog basics

Talend Data Catalog helps you to create a central, governed catalog of enriched data that can be shared and collaborated on easily. It can automatically discover, profile, organize and document your metadata and makes it easily searchable.

Talend Data Catalog editions

The application is delivered in three editions: Standard, Advanced and Advanced Plus. All editions include the essential features of Data Cataloging, such as faceted search, data sampling and profiling, semantic discovery, social curation and data relationship discovery.

The availability of other features varies according to the license edition you have:

  • You can collect metadata from data stores, data models, Data Integration and Business Intelligence (BI) tools, and business applications, using Talend Data Catalog bridges.

    For more information, see Talend Data Catalog Bridges.

  • You can manage metadata by searching for, documenting, analyzing and comparing them, tracing end-to-end data lineage and performing impact analysis.

    The Advanced and Advanced Plus editions include multi version and configuration management.

  • You can use the glossary model to collaboratively build and manage the organization's business concepts and terminology.

    The Advanced and Advanced Plus editions provide a flexible workflow and publication process.

  • You can document any existing data stores by using data models.

    Physical data models are only available in the Advanced Plus edition for data store requirements and database design. Depending on your edition, you can also export data models to any supported DM, DI and BI tools.

  • With the Advanced Plus editions, you can define new custom business models using the metamodeling capability.

User and group assignments

Talend Data Catalog provides default groups:
  • Administrators: The users assigned to this group have the capabilities associated with the Global Administrator and Object Administrator roles. They can also create as many groups and users as necessary and assign them responsibilities.
  • Everyone: All users are assigned to this group and have the capabilities associated with the Application Designer global roles.

Role-based access control

Users have responsibilities given with the group and role assignments.

Talend Data Catalog provides two types of roles:
  • The global roles determine the global responsibilities that users have on all catalog assets.
  • The object roles determine the responsibilities that users have on specific catalog assets, such as glossaries or models.

These roles include a set of predefined capabilities such as management or editing capabilities.
