Privacy policy. SQL Server provides a single setup program to install any or all of its components, including Integration Services. This article highlights important considerations that you should know before you install Integration Services.
Information in this article helps you evaluate your installation options so that your selection results in a successful installation. When you upgrade to the latest version of Integration Services on a computer that has an earlier version of Integration Services, the current version is installed side by side with the earlier version. After you review the installation requirements for SQL Server and ensure that your computer meets those requirements, you're ready to install Integration Services.
To install Integration Services, make selections on the Feature Selection page as follows:. Consider installation additional components for Integration Services. For more information, see the Install additional components section of this article. These components are useful for specific tasks, but the functionality of Integration Services is limited.
To ensure a complete installation of Integration Services, you must select Integration Services on the Feature Selection page. If the ETL server doesn't have an instance of the Database Engine, you have to schedule or run packages from a server that does have an instance of the Database Engine.
One of the reasons why SSIS is so widely used is because of its versatility. Users have complete control to design an ETL process around their own requirements. These include:. The control flow is where you control the workflow of tasks inside a package and the order in which those tasks will be executed.
You can use this through the Control Flow tab. In SSIS, control flows are part of packages and enable the user to execute different tasks. Control flows also include precedence constraints that connect executables, containers, and tasks together while dictating which order to complete the tasks. A data flow is essentially an element that allows you to take data from a source, transform it, and place it into another destination.
For example, you could use a data flow task to take data from a database and transform it into a Microsoft Excel file. You can manage data flows via the Data Flow tab and add them to the control flow.
As part of the data flow, you can choose the transformations you want to prepare the data to reach its end location and complete the ETL cycle. Transformations handle tasks like data cleansing , merging , sorting , joining , and distributing so that you can use the data where you need it. Executables create events at run time and you can use the events handler to perform tasks in response.
Tasks you can perform include cleaning up temporary data storage, retrieving system information, refreshing data in a table, and sending emails to notify you when there is an error or when a task fails.
Event handlers are similar to packages in the sense that they have tasks and containers. You can create custom event handlers in the Event Handlers tab and then add them to a package. In the Package Explorer tab, you can view the hierarchy of elements of a package including connection managers, log providers, executables, precedence constraints, parameters, event handlers, variables, tasks, and containers.
The package explorer is important for checking the contents of a package. One of the fundamental tasks you will have to learn when using SSIS is how to create a package.
SQL Server Integration Services is a platform for building enterprise-level data integration and data transformations solutions. Use Integration Services to solve complex business problems by copying or downloading files, loading data warehouses, cleansing and mining data, and managing SQL Server objects and data.
Integration Services can extract and transform data from a wide variety of sources such as XML data files, flat files, and relational data sources, and then load the data into one or more destinations. You can use the graphical Integration Services tools to create solutions without writing a single line of code.
You can also program the extensive Integration Services object model to create packages programmatically and code custom tasks and other package objects.
