The Oracle Enterprise Data Quality for Product Data (EDQP) Governance Studio is a reporting and graphing application that streamlines the analysis of results from the Application Studio Data Service Application (DSA) job runs. You can create a Governance Studio project to create reports on data quality, analyze transformed data, email records to coworkers, and output the results to a file. The remediation capabilities of the Governance Studio allows you to enrich data by filling in missing category specific attributes assisted by a list of value (LOV) dialog box, the AutoSuggest feature, as well as manually entering missing information.
This guide explains the features and functionality delivered in the Governance Studio and provides examples of how you might use them to build your own projects. These examples are based on a set of use cases to demonstrate Governance Studio features. Because Governance Studio jobs reflect the underlying DSA, it is possible to create many types of jobs to meet the needs of an individual project.
The Governance Studio offers a convenient and easy-to-use interface for launching jobs, managing processes, reporting results, and analyzing and correcting data returned from Application Studio jobs, as well as analyzing all output data created. You can schedule and run jobs synchronously or asynchronously, generate reports, do trend analysis, and identify missing attributes with ease and report discrepancies to coworkers.
The Governance Studio provides a flexible, user-friendly interface for:
Running DSA jobs
Reviewing the output of DSA Jobs
Remediating the output using AutoSuggest LOV or manual intervention
Saving output data
The benefits of using the Governance Studio are described in the following sections.
Data lens reports can help you meet your business goals. Use a data lens to:
Demonstrate value and benefit (ROI) quickly and effectively.
Enable you to visualize results and readily 'connect the dots'.
The Governance Studio enables highly effective reporting in real time using high quality graphical images that reflect the quality of your data along a set of parameters you define to enable downstream processing effectively or communication about your data.
The Governance Studio graphically enhances results from the output of any DSA template and allows you to create and leverage DSA templates for one-to-one alignment with business processes, such as:
General purpose product data assessment
Matching data records between existing and legacy data sources
Proposing alternatives based on search criteria
You start your Oracle DataLens Server, and then use the Welcome Launch Pad to start the Governance Studio by clicking the Governance Studio button. For details, see Oracle Enterprise Data Quality for Product Data Getting Started.
The Governance Studio graphical user interface (GUI) provides the client workspace used to run DSA jobs, view and work with the results.
This section describes the following areas of the client workspace:
The Governance Studio client workspace frame contains useful information and interactive functions including the following:
Indicates the current application and open project.
Provides the status of the project one line at a time. Though this field cannot be resized, the scroll arrows on the right-hand side can be used to view all available status information. The status data does not change based on the selected tab; rather it is a compilation of all data.
Indicates the currently loaded DSA that is used for transforming the project data.
Indicates the number of the row currently selected and the total number of rows available for selection.
Returns you to the last Enterprise DQ for Product application used.
This button opens the Oracle Enterprise Data Quality for Product Data Launch Pad so that you can select other applications.
The time is displayed and when you hover over this field, the date displays.
Indicates the amount of memory cache currently used and the total amount allowed. You can dump the memory cache by clicking on the trash can icon in this interactive field.
Note:This feature is only used for system diagnosis and should not be used unless requested by the support team.
The Governance Studio toolbar allows easy access to the most frequently used Governance Studio functions. Though the set of toolbar buttons remains the same during UI operation the buttons are enabled or disabled based the current state of the interface and the options set. Buttons displayed with shades of gray are disabled. Full-color buttons are enabled. All toolbar buttons are standard push buttons, requiring a single click of the mouse to activate.
The following briefly describes the toolbar buttons from left to right.
The Governance Studio GUI menus provide access to most functions. All of the buttons on the toolbar have a corresponding menu command, which are indicated on each menu with the button icon displaying adjacent to the command. The set of menu commands remains the same during the GUI operation.
Menu commands are enabled or disabled based on the current state of the data lens; commands that are dimmed are unavailable. Some menu commands perform functions that are more complex and are indicated by an ellipsis symbol (...). These commands open dialog boxes to collect information needed to complete the requested function.
Tip:The tooltips appear when you rest your mouse pointer on a menu item, button, tab, icon, or similar content.
The following section briefly describes each of the Governance Studio menu commands and corresponding buttons.

A tab groups like information into easy to read and access areas that include graphs, panes, and text entry boxes. Tabs are displayed in the client workspace directly under the toolbar and can be activated in any order. Not all tabs are available at all times. For example, the Output tabs are not active when you create a new Governance Studio project because the output has not yet been generated.
The standard data tabs provide representations of the aggregate quality and productivity metrics for the project. The graphical output tabs are highly configurable, and double-clicking a bar takes you to the underlying output. You can use these tabs to achieve business objectives in a variety of areas:
Manage data quality by source:
Determine quality of the data source
Allow closed-loop governance of sources
Monitor process effectiveness:
Determine how often a process is invoked, how often it is successful
Identify process improvement opportunities
Assess work-queue visibility and productivity metrics by user
The Source tab is created when the Governance Studio project is based on an input file load or on manual input. If the project specifies an external file, or if the underlying DSA is based on database input, or if the project connects to a scheduled job, there is no Source tab.
The Graph Summary tab provides summaries of the Transformed Data tabs that are configured in the DSA for graphical output. This tab is created if there are at least two graphs to display.
The Output tabs offer item-level validation, approval, edit, and routing. The output is displayed in a single tabular view in the top pane.
There are several types of Governance Studio Output tabs. Each type has different rules governing its creation and different properties that permit you to perform actions on the output each tab displays. Output tabs in the Governance Studio correspond to output steps in your Data Service Application.
The Output tabs provide task-specific User Interfaces (UIs) for any exception process including the following:
Review and approve parsing results
Review and approve potential matches
Reassign low quality items to different workflow/process
Direct edit/update of low quality items
Enables manual intervention while preserving process integrity and efficiency
The following is an example of a match selection process, upon the selection of a row, a parent-child relationship view appears in the bottom pane for match results. These split-screen task panes provide you with an easy to use interactive console to perform tasks associated with reviewing and approval or rejecting duplicates, matches, and functional equivalents
For a new project, Output tabs are not initially displayed in the Governance Studio project. After transforming the Source tab data using the Transform button, the Output tabs are displayed. While transforming data or obtaining source data from a database query, the Job-In-Progress icon in the center of the tab shows that the run is in progress.
For an existing job, the Output tab data is recreated with each job run.
If Output tabs already exist, the Governance Studio compares the column headings of the new data with the column headings of the data in all of the existing Output tabs. If there is a data match (the columns are identical), the existing Output tabs are used. Otherwise, the Governance Studio indicates the mismatch with an error message though it automatically creates the associated Output tab.
After transforming your project data, one or more Output tabs will appear depending on whether the output steps in your DSA specified Governance Studio output. If there are more Output tabs in the Governance Studio console than can display on one page, you can click the left and right Scroll Arrows at the right to scroll to the right or back to the left. Also, you can click the Show Tab List button as shown in following figure to see a list of Output tabs to select them individually.
The tabs that contain tables in the Governance Studio can be filtered to view specific information thereby reducing the number of rows displayed in a table. To filter your table click the Filter button on the toolbar or from the View menu, select Filter.
The Attributes with Suggestions check box is active when the selected tab is an AutoSuggest output tab (see "AutoSuggest Feature") and allows you to search by suggested data.
If the data that you want to filter with is case sensitive, select the Case Sensitive check box to ensure that proper filtering.
Enter a regular expression or a text string that you want to use to filter your data.
You can filter each column of data by selecting the Filter by Column check box.
Each column of the selected tab is displayed. You can enter a regular expression for one or more columns or you click in the All Values column to select a filter value from the auto-populated lists. The Regular Expression and All Values columns are mutually exclusive so an entry or selection in one column resets the other column. The values listed in the All Values column are derived from the values currently in the table so repeated filtering will produce fewer selections. This allows you to refine your filtering based on what is visible. If the values you want to filter on do not appear, unfilter your data, and then filter again.
You can quickly clear all filtering entries by clicking the Clear All Filters. To delete individual filtering entries, select the entry and press the Delete key.
The Filter button is colored green when a filter is active so that you can easily identify that all data is not displayed. When you remove the filter, using the Un-Filter button or from the View menu, select Un-Filter, all of the data is displayed.
The Governance Studio includes two interactive task panes: the Governance Console where data is displayed in tabular form similar to a Microsoft Excel spreadsheet and the Governance Dashboard where graphical representations of the output data are displayed.
The small up/down arrows between the panes on the left-hand side, allow you to resize the panes. In addition, you can fully expand either pane to see more data by clicking on an arrow, which makes the pane inactive. To redisplay the inactive pane, click the opposite arrow and the pane reappears.
There are various context-sensitive (shortcut) menus that appear in the Governance Studio panes when you right-click on data within a pane. The contents of these menus are described throughout this reference.
