Talend Data Catalog concepts

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

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

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

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.

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

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

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

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

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

Metadata-detected classification detects classes by metadata attributes.

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

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

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

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

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