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.

This chapter discusses SSIS customization-the built-in capability of the SSIS platform that allows you to extend the natively provided programmatic elements. In addition to the system-provided tasks and components, including the script task and the script component, the SSIS programming model allows you to implement your own programmatic logic by designing your own control flow tasks (custom tasks) or your own data flow components (custom components).

Typically, a custom task would be needed when none of the system-provided tasks facilitate the specific operation that you need to implement in your SSIS solution; for instance, the built-in File Transfer Protocol (FTP) task does not support Secure FTP, so if you need to access remote file locations using the Secure File Transfer Protocol (SSH FTP), you need to design a custom task.

The most frequent uses of the custom component are custom transformations that either provide operations that are not provided by the built-in components...
