About Visualizations

Oracle LSH provides a Generic Visualization Adapter (GVA) that creates a database schema for a corresponding Business Areas Instance. You can use these schemas to read, analyze and report on Oracle LSH data through any external visualization tool if you have appropriate security permissions. Refer to the section, "Using a Generic Visualization Adapter to View Data" in the Oracle Life Sciences Data Hub Application Developer's Guide for details.

You can use a public API to initialize access to data to the Generic Visualization Business Area based on your security permissions. Refer to the section, "Data Security for a Generic Visualization Adapter (GVA) Business Area" in the Oracle Life Sciences Data Hub Application Developer's Guide for details.

To access data externally, you must log in to an external system. You could then use the BA Namings views to see the available GV Business Areas and their corresponding Tables in Oracle LSH if you have read permissions. Or, you could use a Naming view to select a GV Business Area that you have access to and provide the Business Area schema name to the initialization API to enable data access.

Oracle LSH verifies your user privileges or direct security grants if any, and accordingly enables access to data in the Business Area Tables.

Refer to the section on "Public APIs and Naming Views for Generic Visualization Adapter (GVA)" in the Oracle Life Sciences Data Hub Application Programming Interface Guide for details.

You can also open supported visualization tools directly from the Visualizations subtab of the Reports tab to create data visualizations. Before you can create a Visualization, a Definer must set up a Business Area instance containing pointers to the data you require. The Definer classifies the Business Area instance so that Oracle LSH displays it appropriately, according to your company's classification system, in the Visualizations subtab of the Reports tab. You open the visualization tool within the context of a particular Business Area and have access to the data in that Business Area from that visualization tool. See "Defining Business Areas for Visualizations" in the Oracle Life Sciences Data Hub Application Developer's Guide for more information.

Oracle LSH security controls access to the data.

Creating a Visualization

To find a Business Area instance and create a Visualization:

1. Go to the Visualizations subtab of the Reports tab.

2. From the Select Hierarchy drop-down list, select the classification hierarchy that applies to the data you need, according to your company's classification system.

   Oracle LSH populates the lower part of the screen with nodes representing the high-level values of the classification hierarchy you selected.

3. Expand the + nodes to see more specific classifications until you find the Business Area you are looking for.

   Note:

   If you cannot find the Business Area you are looking for, it is possible that the Oracle LSH Definer did not classify it. You must contact the Oracle LSH Definer responsible for creating and maintaining Business Areas, or if you have sufficient privileges, classify the Business Area yourself.

   See "Classifying Objects and Outputs" in the chapter on common development tasks in the Oracle Life Sciences Data Hub Application Developer's Guide for instructions.

4. Click the Business Area's icon:

   Oracle LSH opens the Launch Visualization screen.

5. If you have the necessary security privileges and want to view noncurrent or blinded data, click Launch Settings. See "Setting Data Currency and Blinding Values". All blind breaks are audited.

   If you want to see current, nonblinded data, click Launch Visualization. Oracle LSH launches the appropriate visualization tool and allows you access to the correct data.

Note:

When you launch an OBIEE visualization, log in with your Oracle LSH username and password in OBIEE.

Setting Data Currency and Blinding Values

This section contains the following topics:

• Setting the Blind Break Value

• Setting the Shared Snapshot Label Value

You can determine the blinding status and currency of the data you see by clicking the Launch Settings button and selecting a value for Blind Break and Shared Snapshot Label.

Setting the Blind Break Value

This setting is relevant only when one or more source Table instances either currently or formerly contained blinded data. Special privileges are required to view real data that is either currently blinded or was formerly blinded.

Note:

You must have Read Data privileges in order to see any data at all.

If you launch the Oracle Business Intelligence Presentation Services from outside Oracle LSH (using the Presentation Services public URL), you cannot see blinded data regardless of your privileges.

The following choices are available depending both on the state of the data and on your security privileges:

• Not Applicable. If none of the data has ever been blinded, the only option available is Not Applicable. No special privileges are required.

• Dummy. If any of the data has ever been blinded, this option appears. If you do not have the privileges, this is the only option available. If you do have the privileges required, you see Dummy plus one of the following options, depending on the state of the data and your privileges. Select Dummy to view dummy (not real) data.

• Real (Blind Break). If any of the data is currently blinded, and you have the required privileges, you can select this option to view real data in Oracle Business Intelligence Enterprise Edition according to your company's policies. The table(s) containing the blinded data remain blinded after you run the visualization.

• Real (Unblinded). If any of the data was formerly blinded but is currently unblinded and none of the data is currently blinded, and you have the required privileges, you can select this option to view real data, according to your company's policies.

Setting the Shared Snapshot Label Value

If all the relevant Table instances share one or more snapshot labels, those snapshot labels appear in this drop-down list and you can select one. See "Setting Source Data Currency" for more information on snapshot labels.

In addition, you normally have the option to view the current data.
