A repository stores data and metadata (information about your data). Using Trillium, you can discover the following types of information about your data:
Data structures, contents, and relationships
Data compliance with business rules
Data statistics, drill-down details, and data patterns
Data trends and changes over time

Documentation of data observations, compliance issues, and more
You can create one or more repositories to store your data. Each repository belongs to a specific repository server.
