Microsoft SQL Server 2012 Integration Services: An Expert Cookbook

Overview of this book

SQL Server Integration Services (SSIS) is a leading tool in the data warehouse industry - used for performing extraction, transformation, and load operations. This book is aligned with the most common methodology associated with SSIS known as Extract Transform and Load (ETL); ETL is responsible for the extraction of data from several sources, their cleansing, customization, and loading into a central repository normally called Data Warehouse or Data Mart.Microsoft SQL Server 2012 Integration Services: An Expert Cookbook covers all the aspects of SSIS 2012 with lots of real-world scenarios to help readers understand usages of SSIS in every environment. Written by two SQL Server MVPs who have in-depth knowledge of SSIS having worked with it for many years.This book starts by creating simple data transfer packages with wizards and illustrates how to create more complex data transfer packages, troubleshoot packages, make robust SSIS packages, and how to boost the performance of data consolidation with SSIS. It then covers data flow transformations and advanced transformations for data cleansing, fuzzy and term extraction in detail. The book then dives deep into making a dynamic package with the help of expressions and variables, and performance tuning and consideration.

Introduction


SSIS is a Rapid Application Development tool. This means that SSIS developers won't need to write any code to do operations. On the other hand, we saw in Chapter 8, Scripting, that there are two script components that help developers to write their own customized .NET code to do any specific operation which is not listed in SSIS built-in components. All of these features are not enough for calling an ETL tool as an enterprise, because enterprise environment needs extreme dynamism and open-handed environment for developers. And fortunately, SSIS can be done from development to execution with .NET programming. You can create a package with some lines of .NET code, develop control flow and data flow all in code, and finally deploy and execute it with programming. Let's call this great feature SSIS programming.

SSIS programming means doing everything with code. You don't need to do anything with SSDT, but you need Visual Studio. .NET framework and obviously SSIS engine have to be...
