Creating custom comparison filters

You can create custom filters to filter out properties or attributes of data objects when you run a comparison.

Before you begin

To create custom comparison filters, you must first compare data objects to each other.

About this task

The workbench provides several built-in filters that you can enable or disable. You can also create custom filters to use when you compare data objects. For example, if you would like to filter out the dataCapture attribute of a data object, you can create a custom comparison filter. When you enable the custom comparison filter, the differences in those attributes or properties are not displayed as differences in the Compare editor.

You can only create custom filters for properties or attributes of a data object. You cannot filter out entire objects, such as a table, by creating custom filters.

Procedure

  1. Open the Create Custom Filter window. In the Compare editor, right-click the attribute or property that you want to filter, then select Create Custom Filter. For example, right-click the dataCapture property of a table. The Create Custom Filter window opens.
  2. Specify a description for the new filter, then click OK to create the filter.

Results

The custom comparison filter is created.

What to do next

When you run a comparison, you can enable or disable this filter on the Custom Filters page of the comparison wizard. This wizard page appears only if you create custom filters for the type of comparison that you are running. To enable or disable filters by default, update the options for the comparison type on the Custom Filter Configuration page of the Preferences window.
You can create custom filters for the following comparison types:
  • Physical data model objects for supported database vendors
  • Logical data model objects
  • Domain data model objects
  • Glossary model objects
  • Transformations from logical data models to existing physical data models
