Course description

The data flow task is a special control flow task that moves data from a data source to a data destination, optionally transforming the data in various ways as it moves. It is so important and complex that unlike any other control flow tasks, the data flow task has its own designer in SQL Server Data Tools. This is where you’re likely to spend most of your time when developing any non-trivial Integration Services package that moves data rather than just performs other control flow tasks. As a data flow moves data from a source to a destination, you can perform various data flow transformations on that data. These transformations tasks let you look up data from an external source change the contents of a field to upper case sort the data, merge the data flow with other flows, and much more. The data flow task is the single most important task in a control flow and performs the majority of the work in an ETL, Extract, Transform and Load, an ETL process. In this course you’ll learn about the various components that you can use to build the data flow. Including the various data sources and destinations that you can use to read data and store it in its final resting place. Then you’ll learn about the transformations that you can use to modify the data and its scheme as it moves through the data flow pipeline. You can change a fields data type, modify its contents, split the data flow in to multiple pipelines, merge data flows, perform various kinds of look up, and much more. Data flows are key part of Integration Services and its well worth the time getting to know them well.


This course assumes that you have a basic familiarity with the concept of relational databases and a basic understanding of what SQL Server is and the high-level tools in it, as well as how to create and manage objects using Management Studio. You should also have a basic understanding of how SQL Server implements security, including its authentication and authorization schemes, and how to assign permissions on securable objects to principals. You should know the fundamentals of Transact-SQL to write queries to retrieve data and join data from multiple tables, and how to execute scripts using the query editor in Management Studio. You must also know how to connect to an instance of SQL Server 2012 using the various connection dialog boxes in Management Studio and development tools. It will be very helpful, but not absolutely necessary, to have experience with .NET development using Visual Studio 2012 or later for the portions of the course that deal with SQL Server Data Tools (which is a lot of it). At the very least, we’ll assume that you are well familiar with the Visual Studio user interface. This course assumes no prior knowledge of SQL Server Integration Services.
