Metadata repository
Using Talend data quality, you can connect to data sources to analyze their structure (catalogs, schemas, and tables), and stores the description of their metadata in its metadata repository. You can then use this metadata to set up metrics and indicators.
For more information, see Creating connections to data sources.
One specific feature of interest as well is a report database where you can keep a history of created reports and share results among team members. For more information, see Managing the report database.
