Export a Domain to a .dqs File

  • Artikel

Applies to: SQL Server

This topic describes how to export a domain to a .dqs file in Data Quality Services (DQS). You can export a domain or an entire knowledge base to a data file. For information about exporting a knowledge base, see Export a Knowledge Base to a .dqs File.

Exporting a domain from one knowledge base to a .dqs data file, and then importing it to another knowledge base simplifies the knowledge generation process, saving time and effort. It enables you to share a domain and its knowledge with others.

You can export either a single domain or composite domain. A .dqs file containing a single domain includes all domain data including domain properties, values, and rules except for the attached reference data information. A .dqs file containing a composite domain includes all composite domain data, including all domain data for the domains that are contained in the composite domain, and the composite domain properties, relations, and rules, except for the reference data information. You must attach the domain or the composite domain to appropriate reference data services again, if required, after importing the .dqs file. Both published and unpublished data is exported.

The .dqs data file created by the export process is encrypted, so the contents cannot be viewed.

Before You Begin

Prerequisites

To export a domain to a .dqs data file, you must have created and selected a single domain or a composite domain containing multiple single domains. You do not need to have a .dqs file to export into; one will be created for you.

Security

Permissions

You must have the dqs_kb_editor or the dqs_administrator role on the DQS_MAIN database to export a domain to a .dqs data file.

Export a domain to a .dqs file

You can export from any Domain Management page. The export command is available from both a control in the user interface and from a command in the context menu of the Domain List pane.

  1. Start Data Quality Client. For information about doing so, see Run the Data Quality Client Application.

  2. In the Data Quality Client home screen, open a knowledge base in the Domain Management activity.

  3. In the Domain Management page (with any tab selected), select a single domain or a composite domain in the Domain list.

  4. Click the Export Knowledge Base data icon above the domain list, and then click Export Domain. Alternatively, you can right-click the domain in the Domain list, point to Export, and then click Export Domain.

  5. In the Export to Data File dialog box, move to the folder that you want to save the file in, name the file or keep the default name, keep DQS Data Files (*.dqs) as the Save as type, and then click Save.

  6. In the Export Domain dialog box, verify that the status line in the dialog box indicates that the export completed. Click OK.
