Data Quality Services

For data to be usefully analyzed, it must be consistent, accurate, and trustworthy. When incoming data is non-uniform, duplicated records are created and the data starts losing its value. In order to counteract with this issue, SQL Server’s Data Quality Services (DQS) helps monitor and maintain incoming data, and reduplicates existing data using rules-based matching.

The amount of data that we generate and work with daily, keeps increasing in volume. We are responsible for keeping this data clean so we can get the most value out of its analysis. For example, we can imagine how hard it would be to perform aggregations on sales per vendor if the vendor is identified by name, and most of the vendors are entered with several different spellings in their name, depending on the data source. Here is where Data Quality Services come in, as a necessary part of our ETL processes.

Data Quality Services (DQS) is a fairly new part of SQL Server (available in Enterprise, Business Intelligence and Developer editions since SQL Server 2012), which performs the tasks of monitoring and maintaining the new coming data in good condition.

There are several challenges in the way of the perfect dataset. The incoming data can be:

• Inconsistent
• Invalid
• Incomplete
• Inaccurate
• Non-uniform
• Duplicate

These flaws can easily be caused either by incorrect data entry, system failure, data corruption, or when Master Data Services are not used within the enterprise.

Our DQS Consultants are here to provide you with a fairly flexible solution to these problems, and save you from a lot of tedious work.
