SQL Server Data Quality Services (DQS) is a new Knowledge-Driven Data Quality feature set of the upcoming Microsoft SQL Server “Denali” release aimed at the data stewards and IT professionals who seek to improve the quality of their business data. In this session, we describe the concept and main principles behind Data Quality Services from Microsoft, and demo the main capabilities of the product, such as knowledge management, cleansing, matching and profiling.
Imagine you will be able to download, install, and use DQS and after this session. Within minutes you will be able to make simple DQS knowledgebase design choices with minimal developer investment. You will be able to pull data from SQL Server table or Excel worksheets, such as incomplete and unsure customer addresses or product values or almost any custom entity that you want. DQS have specific activities to clean and de-duplicate that data to make suggestions and corrections. DQS presents the results in an interactive and simple-to-use GUI tool to approve, reject, or amend the changes before saving them to the destination of your choosing. Cleansing tasks can be automated with the SSIS DQS Data Cleansing component as well. Most any business user will quickly see the value of DQS and walk away feeling ready to show off their new found smarts to the rest of the team.
