Importing and Exporting Knowledge

  • Article

You can create knowledge bases and domains directly in the Data Quality Client application, or you can import knowledge into, or export it from, a knowledge base. In the Data Quality Client application, you can use a data file for import and export operations, or an Excel file for import operations. The data file used is an encrypted file that is created by Data Quality Services (DQS) with a .dqs extension. The files created by Microsoft Excel can have an extension of .xlsx, .xls, or .csv. These operations give you more flexibility in building and sharing the knowledge that you use to perform data cleansing and matching.

Important

You can export all the knowledge bases in your Data Quality Server to a DQS backup file (.dqsb) at once by running the DQSInstaller.exe file from the command prompt. Similarly, you can import all the knowledge bases from a DQS backup file (.dqsb) to your Data Quality Server at once by running the DQSInstaller.exe file from the command prompt. For information about doing so, see Export and Import DQS Knowledge Bases Using DQSInstaller.exe in the DQS installation guide.
