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 Fields and locate key columns of credit card information across multiple databases. Adjusting the filter to Resources only returns results when a table contains "credit" in the title.

You can access Galaxy View in two ways:

  • Data Canvas

    To access Galaxy View from the Data Canvas, select a folder or other resource, click Actions and select View Galaxy.

  • Business Glossary

    To access Galaxy View from the Business Glossary, select a glossary or term, click Actions and select View Galaxy. You can also select Galaxy from the View As drop down menu, which displays the Galaxy View of the complete Business Glossary regardless of the glossary or term selected.

ImportantGalaxy View in Business Glossary has more features like relationship information and additional filters.

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

  • Search

    Enter a keyword and select Search to find specific information within the resources. For example, enter "address" to just show those sources, tables, and columns containing address information.Searching in Galaxy View
