Searching

Classifications

In the Classification option, selecting a classification displays all the entities that are marked with that classification. Locate a specific classification using the search box or browse the classification hierarchy that you defined during classification creation. The Classification tab displays all related assets, including processes.

Glossary

In the Glossary option, selecting a term displays all the entities that are marked with that term. Locate a specific term using the search box or browse terms by glossary. Use the category view to browse the hierarchy of your organization’s business glossary. Selecting a category displays its assigned terms in the display pane. When you select one of those terms, Atlas displays the associated entities.

When you run a search and Atlas returns results, you see a paged-list of entities that match the search criteria. From here, you can go back to the search options and further refine your search or use controls to change how the search results are presented.

Search results

When Atlas returns search results, the user interface displays a paginated list of entities that match the search criteria. You can return to search options to further refine your search or use the available controls to change the search result presentation.

1. View the search criteria set in the Search panel.
2. By selecting the checkboxes, remove the following entity types from the result list:
   • Sub-entities

   • Entities marked as deleted (historical entities)
3. Control which attributes of the entities are shown in the columns.
4. Download the selected search results as a CSV file.
5. By selecting the checkboxes, mark multiple entities for export or for applying classifications or terms.
6. Add classifications by clicking the icon. By clicking the icon, view the rest of the classifications, that did not fit the screen.
7. Add terms by clicking the icon. By clicking the icon, view the rest of the terms, that did not fit the screen.

Viewing entity details

When you click a link for an entity in the search results, Atlas opens an entity detail page that includes the metadata collected for the entity. The detail page organizes the entity content in tabs:

Properties

The Properties tab includes the system metadata collected for this entity and any user-defined properties added. It also contains a list of labels applied to the entity. You can use values from any of the "string" data type properties to find this entity using free-text search.

Lineage

Atlas user interface displays a lineage graph for each entity. The graph appears in the Lineage tab in the entity details page. For data asset entities, the lineage graph shows when the entity was an input or an output from an operation. For process entities, the lineage graph shows all input and output entities used by or produced by the operation.

Relationships

This tab lists the other entities that are associated with this entity as relationships. Use it to navigate among entities. The special relationship types input and output include the entities that make up lineage.

Classifications

The Classifications tab shows the classifications associated with this entity (which are also shown in the top section of the detail page). It allows you to add, update, or remove classifications from the entity.

Audits

Atlas records the changes that occur to entity metadata. The changes are listed in the Audit tab in the entity details page. Audits show when Atlas updates the entity's metadata, including the following changes:

• Classifications added or removed
• Entity attributes updated
• Labels added, updated, or removed
• Relationships added, updated, or removed
• Glossary terms added or removed

Schema

When the current entity is a table, the Schema tab appears and lists columns in the table. Use this tab to drill into a specific column or to add classifications to columns (no need to open the detail page for the column to add a classification).
