Using Galaxy View

You can use the Galaxy View feature to quickly view the structure of your data and its details. This feature is especially useful when you want to view information that is not easily visualized using the navigation tree in the Data Canvas. When the data is presented in Galaxy View, you can see the relationships in your data from a bird's eye view, and drill down into the data for specific details.

When using a keyword search in Galaxy View, you can limit the scope of the returned data using filters. For example, an information security officer may want to find all the databases that contain credit card information. In Galaxy View, they can search for “credit” while setting the filter to Columns and locate key columns of credit card information across multiple databases. Adjusting the filter to Tables only returns results when a table contains "credit" in the title.

You can access Galaxy View from Data Canvas or from Business Glossary.

  • To access Galaxy View from the Data Canvas, select a folder or other resource, click Actions and select View Galaxy.
  • To access Galaxy View from the Business Glossary, select a glossary or term, click Actions and select View Galaxy. You can also select a glossary or term and select Galaxy from the View As drop down menu.

Here are the key tasks you can perform in Galaxy View:
