DQS Cleansing Transformation Editor Dialog Box

Use the DQS Cleansing Transformation Editor dialog box to correct data using Data Quality Services (DQS). For more information, see Data Quality Services Concepts.

To learn more about the transformation, see DQS Cleansing Transformation.

  1. Add the DQS Cleansing Transformation to Integration Services package, in SQL Server Data Tools (SSDT).

  2. Right-click the component and then click Edit.

Data quality connection manager

Select an existing DQS connection manager from the list, or create a new connection by clicking New.

New

Create a new connection manager by using the DQS Cleansing Connection Manager dialog box. See Set the options in the DQS Cleansing Connection Manager Dialog Box

Data Quality Knowledge Base

Select an existing DQS knowledge base for the connected data source. For more information about the DQS knowledge base, see DQS Knowledge Bases and Domains.

Encrypt connection

Specifiy whether to encrypt the connection, in order to encrypt the data transfer between the DQS Server and Integration Services.

Available domains

Lists the available domains for the selected knowledge base. There are two types of domains: single domains, and composite domains that contain two or more single domains.

For information on how to map columns to composite domains, see Map Columns to Composite Domains.

For more information about domains, see DQS Knowledge Bases and Domains.

Configure Error Output

Specify how to handle row-level errors. Errors can occur when the transformation corrects data from the connected data source, due to unexpected data values or validation constraints.

The following are the valid values:

  • Fail Component, which indicates that the transformation fails and the input data is not inserted into the Data Quality Services database. This is the default value.

  • Redirect Row, which indicates that the input data is not inserted into the Data Quality Services database and is redirected to the error output.

For information on how to map columns to composite domains, see Map Columns to Composite Domains.

Available Input Columns

Lists the columns from the connected data source. Select one or more columns that contain data that you want to correct.

Input Column

Lists an input column that you selected in the Available Input Columns area.

Domain

Select a domain to map to the input column.

Click in the field to modify the column name.

Status Alias

Lists the column that contains status information for the corrected data. Click in the field to modify the column name.

Standardize output

Indicate whether to output the data in the standardized format based on the output format defined for domains. For more information about standardized format, see Data Cleansing.

Confidence

Reason

Indicate whether to include the reason for the data correction.

Appended Data
