Data quality services sql server 2012

How do you install SQL Server data tools? How to deploy SSIS package? What is the BI stack? SQL Server Data Quality Services (DQS) is a knowledge-driven data quality product.

I have recently started to explore the same and I am really learning some good concepts. Here are two very important blog posts which one should go over before continuing this blog post about Data Quality Services.

DQS provides the following features to resolve data quality issues. DQS makes it easy for domain experts to build and improve a data quality knowledge base over time and can be reused by other solutions like Integration Services and Master Data Services. Feodor Georgiev provides a thorough walkthrough on setting up DQS and creating the rules it uses to function as a first step towards data cleansing. DQS_MAIN contains DQS stored procedures, the DQS engine, and published knowledge bases.

A brief overview of DQS.

You install DQS with SQL , and you have to configure it. Use that knowledge to perform data cleansing, matching and profiling. During the installation, you are prompted to type a password for the database master key.

DQS enables to discover, buil and manage knowledge about your data. Open WinX menu by holding Windowsand Xkeys together, and then click Programs and Features. When you create a new knowledge base, you can do so from scratch, or you can use an existing knowledge base as a starting point.

DQS:n avulla dataa voidaan ”siivota”, eli poistaa duplikaatit tai muokata kirjoitusasu yhteneväksi niin että tuloksena saadaan oikeanlainen ja yhtenevä datajoukko joka voidaan siirtää esimerkiksi data warehouse-järjestelmiin. This course describes how to implement a data warehouse platform to support a BI solution. It includes database for storing the knowledgebase information and the policies and rules that are applied to business data during cleansing and matching activities. It also includes the DQS engine, which is what applies all the information and rules in the databases.

This is not a feature of Integration Services , but it is very much connected to the data cleansing processes within SSIS. In fact, there is a data transformation called the DQS Cleansing Task. This task connects to DQS, enabling you to connect incoming Data Flow data and perform data cleansing operations. I’ll share a quick demo of how you can use Regular Expressions in Data Quality services to clean records.

DQS is a knowledge-driven solution that provides both computer-assisted and interactive ways to manage the integrity and quality of your data sources. You need to complete the installation manually by launching DQSInstaller. The installation will ask for a strong Database Master Key.

You can supply something like Pa$$w0rd or any complex password of your choice.

Database administrators have a significant role to play in data management, of course. Master Data Services is an extensible Master Data Management (MDM) platform, which is built on top of the SQL Server database engine and Windows Communication Foundation (WCF).
