Overview of this book

SQL Server Integration Services is a tool that facilitates data extraction, consolidation, and loading options (ETL), SQL Server coding enhancements, data warehousing, and customizations. With the help of the recipes in this book, you’ll gain complete hands-on experience of SSIS 2017 as well as the 2016 new features, design and development improvements including SCD, Tuning, and Customizations. At the start, you’ll learn to install and set up SSIS as well other SQL Server resources to make optimal use of this Business Intelligence tools. We’ll begin by taking you through the new features in SSIS 2016/2017 and implementing the necessary features to get a modern scalable ETL solution that fits the modern data warehouse. Through the course of chapters, you will learn how to design and build SSIS data warehouses packages using SQL Server Data Tools. Additionally, you’ll learn to develop SSIS packages designed to maintain a data warehouse using the Data Flow and other control flow tasks. You’ll also be demonstrated many recipes on cleansing data and how to get the end result after applying different transformations. Some real-world scenarios that you might face are also covered and how to handle various issues that you might face when designing your packages. At the end of this book, you’ll get to know all the key concepts to perform data integration and transformation. You’ll have explored on-premises Big Data integration processes to create a classic data warehouse, and will know how to extend the toolbox with custom tasks and transforms.

Managing custom component versions

Over time you might need to make changes to a custom component, for instance because you needed to optimize or refactor the code, implement new features, or replace the external assemblies. As long as the interface of the component (its custom properties and its inputs and outputs) remain unchanged in a later version, you simply deploy the new version to the destination environments, register it in the GAC, and the new version of the component will be used the next time the package is executed or edited in SSDT. You do not even have to modify its version number.

However, if the change affects the components interface - for instance, if you need to add, remove, or modify any of its custom properties - you need to make the component upgradable. This upgrade is performed automatically - at design time or at run time - by invoking a special design-time method of the Microsoft.SqlServer.Dts.Pipeline. PipelineComponent base class, namely the PerformUpgrade() method...
