In this article we will thoroughly discuss about (DQS) DATA QUALITY SERVICES in MSBI(SSIS, SSAS and SSRS) we have to tried to keep this article as simple as possible to deliver the most of out it to the reader.
So without wasting time here and there, we will come to straight point and directly start with our article agenda around (DQS) DATA QUALITY SERVICES in MSBI

Our topic hero, "DQS" which is a service which will help common end user as well as MSBI developer to make their raw data into a good data.
Before moving with DQS service we would also like to bring in notice that the end user resolve maximum amount of bad data issue just before it goes into ETL process(SSIS).

Nataraj, Staedler and Pencil -> pencil
kores and rubber -> rubber
