You can view output results for data rules, metrics, and
rule sets from four different parts of the IBM® InfoSphere® Information Analyzer workspace. You can view results from the InfoSphere Information Analyzer My Home workspace, from the project dashboard,
or from the Data Quality workspace.
The
View Output workspace will
give you specific details about your data rules, rule sets, and metrics,
in a
History workspace that outlines a textual
summary of the data quality element history, as well as graphical
views showing the trend of the execution results. The output displayed
differs based on the way you configured your output when you created
each individual data rule, rule set, and metric. The following output
elements are displayed for the following data quality items:
- Data Rules
- In the History workspace, you can view
details about the individual executions of your data rules, such as
statistics and benchmarks. Click Make Baseline to
set the starting point in the graphical view. You also have the option
of adding notes to the History workspace by
clicking the Note icon.
- To view the graphical history of a data rule, click the graph
icon in the bottom left of the screen. You can change the start date
and end dates of data rule executions you want to see in the graph,
as well as change the view to display either % Not Met or #
Met. Use the legend in the lower left side of the screen
for details about the components of the graph.
- Click View Details from the History workspace
to display details for a specific data rule execution. In the View
Details workspace, click the Overview or Results tab
to view statistics and results about a particular data rule execution.
You can see all exception details based on how you configured your
output. What you will see here matches your output configuration.
The fields you see are based on the columns you selected to include
when setting output for a particular data rule. You can click Export to
export the data rule data to a fixed or delimited text file.
- Rule Sets
- In the History workspace, you can view
details about the individual executions of your data rules, statistics,
and benchmarks. Click Make Baseline to set
the starting point in the graphical view. You also have the option
of adding notes to the History workspace by
clicking the Note icon. Click View
Details to display details for a specific data rule execution.
- To view the graphical history of a rule set, click the graph icon
in the bottom left of the screen. You can choose from the following
graphical views:
- Validity
- Confidence
- Baseline Comparison
- Number of Rules Not Met
You can change the start date and end dates of rule set executions
that you want to see in each graph. Use the legend in the lower left
side of the screen for details about the components of the graph.
- In the View Details workspace, click the Overview or Results tab
to view statistics and results about a particular data rule execution.
The Overview workspace provide provides details
about the rule set, such as the mean, the standard deviation, statistics,
and benchmarks.
- The Results tab has four different views.
Click the view you want to see in the Select View menu
on the left side of the screen:
- Record
- This displays all of the records for a rule set. You can view
all of the rules not met by for each execution result for a rule set.
When you highlight an execution record for a rule set, you can see
the individual records that violated the rule in the Rules
Not Met By Selected Record workspace on the bottom of
the screen.
- Rule
- This displays all of the rules for a rule set. You can select
multiple rules at one time. You can select Union to
show all records that failed one of the rules, or both of the rules,
or you can select Intersection to show records
that failed both ones that failed both rules.
- Distribution
- This view shows the percent of records that had one ore more violations.
You can sort records by # of Rules Not Met or %
of Rules Not Met.
- Pattern
- This view shows the pattern of your rule set records. It can show
information such as, when rule A broke, rule B also failed 97% of
the time. It provides a confidence to show if there is an association
between two rules. It helps you find correlations between rule patterns
and shows any dependencies or relationships between two rules.
- You can see all exception details based on how you configured
your output. What you will see here matches your output configuration.
The fields you see are based on the columns you selected to include
when setting output for a particular data rule. You can click Export to
export the data rule data to a fixed or delimited text file.
- Metrics
- In the History workspace, you can view
details about the individual executions of your metrics. Click Make
Baseline to set the starting point in the graphical view.
You also have the option of adding notes to the History workspace
by clicking the Note icon. Click View Details to
display details for a specific metric execution.
- To view the graphical history of a metric, click the graph icon
in the bottom left of the screen. You can change the start date and
end dates of data rule metric executions you want to see in the graph.
Use the legend in the lower left side of the screen for details about
the components of the graph.
- Click View Details from the History workspace
to display details for a specific metric execution. In the View
Details workspace, click the Overview or Results tab
to view statistics and results about a particular metric execution.
You can see all exception details based on how you configured your
output. What you will see here matches your output configuration.
The fields you see are based on the columns you selected to include
when setting output for a particular metric. You can click Export to
export the data rule data to a fixed or delimited text file.
