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.

Package configuration: Legacy method to inter-relation


Legacy Package Deployment Model has the ability to configure packages also. Package configuration is the way we handle configuration in Legacy Deployment Model. Packages are different objects in legacy model which has no relation to the project, so we cannot apply project scope parameters or such things for them. However, package configuration solved this problem in another way.

Package configuration consists of properties and values which will be set outside of the package and can be used inside the package simply. There are five types of package configurations, four of them are based on the location of configuration values, and one of them is for passing values between packages.

We will take a look at some of the most common package configurations in this recipe with a sample like what we generated in the very previous recipe (Parameters), but this time we work with package configuration instead of parameters.
