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.

Designing a custom task

To design a custom control flow task, you create a DOT.NET assembly based on the Class Library Visual Studio template; the task's definition must be placed in a class derived from the Task base class, of the Microsoft.SqlServer.Dts.Runtime namespace (located in the Microsoft.SqlServer.ManagedDTS.dll assembly). This class also needs to implement the DtsTaskAttribute that is used to identify the class as an SSIS task and provide the elementary properties used when implementing the custom task in SSIS control flows.

Optionally, you can provide a custom graphical user interface for the custom task, which will be used as the task editor when the task is configured during SSIS package development. If a custom editor is not provided, the custom task can be edited by using the built-in advanced editor.

The task base class provides two methods that you need to override, and in them provide your custom code to:

  • Validate the configuration of the task. This method is called automatically...
