SQL Server 2017 Integration Services Cookbook

By: Christian Cote, Dejan Sarka, David Peter Hansen, Matija Lah, Samuel Lester, Christo Olivier

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.

Preface

Framework calls in EP_Staging.dtsx


This section of the book introduces an ETL framework. The purposes of such a framework are the following:

  • Store execution statistics outside the SSIS catalog: although the Microsoft SSIS team always enhances catalog performance, keeping all execution data in the catalog will degrade catalog performance.
  • Align the data in such a way to be able to do some analytics on the execution data. In that case, think of the framework as an SSIS package execution data warehouse.

The following diagram is the ER diagram of the framework tables. These tables are stored in the SystemLog schema:

Here's the table list and their purposes:

  • LoadApplications: This table contains one value: SSISCookBook sample solution. The purpose of this table, coupled with the Loads table that we'll describe next, is to group many SSIS executions together into a common solution. For example, in this book, we'll have an entry-point package that will call the execution of the entry-point packages...
