These definitions will help you understand the main concepts in Talend Cloud Data Catalog.

  • Catalog

    A catalog is an inventory of data assets, such as database tables, Data Integration Jobs or BI reports.

  • Metadata

    Metadata is structured information that describes a data resource, such as its name, type, location, author, date created, size and relationships with other data objects.

  • Metadata repository

    Metadata repository stores metadata created or imported from data sources, project configurations and reports.

  • Metadata harvesting

    Metadata harvesting means collecting metadata from a data source, by using Talend Cloud Data Catalog bridges. The metadata is imported in a model and stored in the metadata repository.

  • Bridge

    A bridge is a platform-dedicated connector. It uses a specific driver to connect to a source tool and collect its metadata.

    You can import metadata from data stores, Data Integration tools, Business Intelligence tools and business applications.

  • Stitching

    Once created, models are linked together in a configuration to define the data flow in the information system.

  • Configuration

    A configuration is an environment or workspace where you connect models to each other to build a global schema of the enterprise information system.

  • Glossary

    A glossary captures and defines the enterprise vocabulary to build a common language that everyone can understand.

  • Data profiling

    Data profiling is the process of examining the data from data sources imported in your catalog and collecting statistics and information about this data.

  • Data sampling

    Data sampling allows to preview the content of database tables and data files imported in your catalog.

  • Data class

    Data classification helps you to detect, understand and classify the nature and purpose of the elements contained in the data sources imported in your catalog.

  • Data-detected class

    Data-detected classification detects common data patterns automatically based on predefined enumeration, patterns and regular expressions.

  • Metadata-detected class

    Metadata-detected classification detects classes by metadata attributes.

  • Sensitivity label

    A sensitivity label can be applied to repository objects to determine their level of confidentiality.

  • Global role

    The global role determines the global responsibilities that you have on all catalog assets.

  • Object role

    The object role determines the responsibilities that you have on specific catalog assets, such as glossaries or models.

  • Worksheet

    A worksheet allows to perform and save your searches or customize the tabs in the details pages.

  • Dashboard

    A dashboard provides an insight of the catalog assets and is customizable to meet your specific needs.
