Importing and Exporting Knowledge
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.
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.
You can perform the following import and export operations:
Export a domain in a knowledge base to a .dqs data file
Import a domain from a .dqs data file into an existing knowledge base
Export an entire knowledge base to a .dqs data file
Import an entire knowledge base to a .dqs data file
Import values from an Excel file into a domain
Import domains from an Excel file into a knowledge base
Import knowledge gathered during cleansing into a knowledge base
Building a knowledge base by running knowledge discovery and interactively managing knowledge
Creating a single domain, and adding knowledge to the domain.
Creating a composite domain, and adding knowledge to the domain.
