Adding Processors

OEDQ comes with a library of processors for processing your data.

To add a processor to your process:

Ensure your process is open on the Canvas:

Double-click on the Reader to configure it to read data from Staged Data (such as a Snapshot), a View, or a real time data provider.

Select the data that you want to read, and the attributes from the data that are relevant to your process.

Add a processor from the Tool Palette to the process by clicking on a processor and dragging it to the Canvas
Connect the processor to the data from the Reader by joining the arrows:

Configure the processor by selecting its input attributes:

The blue arrow icons indicate that the latest version of the attribute will be used as the input. This is especially important when transformation processors have been used. See About Transformation Processors for further information.

Note:For Profiling processors, it is common to analyze the data in all attributes to discover issues of interest about the data.

Note: Once a processor is correctly configured, it no longer appears with a blue background.

Once you have connected the set of processors that you wish to use, click on the Quick Run process button on the Toolbar to run the process and look at the results:

The Canvas background changes to blue to show you that the process is running. (Also, the process icon in the Project Browser turns green so that other users connected to the same host can see that it is running.)

Note:The process is locked and cannot be edited while it is running.

When the process has finished, the processors no longer appear with a shaded background, and you can browse on the results for each processor by clicking on the processor on the Canvas, and viewing its results in the Results Browser:

Drill-down on the metrics to see the relevant data for the metric.

Having successfully created a process, you can now begin to create Reference Data for the validation and transformation of your data.

Ambiguous Latest Attribute

When selecting the input attributes for a processor, it is possible that some attributes may have an ambiguous latest version. This happens whenever an attribute exists on two different paths, and has been transformed on either or both of these paths. Where this happens, the top level attribute (or latest version) will be greyed out, and will not be selectable. In this case, you need to select the specific version of the attribute that you wish to use by expanding on the attribute and viewing all its possible versions.

For example, the Upper Case processor below has been configured with 2 input paths, from 2 different processors. The Replace processor transforms a 'title' attribute:

The Upper Case Processor configuration would appear as follows, with the latest version of the title attribute greyed out to indicate that it is ambiguous and therefore not available for use. In this case, you need to select one of the specific attributes listed under the title attribute.

This scenario will commonly occur while configuring the Merge Attributes processor, as this is often used to unite separate processing paths.
