Tasks are interlinked using precedence constraints , which define package workflow by determining a downstream task such that a resulting action depends on the outcome of an upstream task or on the value of an arbitrary, dynamically evaluated expression. Tasks can be grouped using containers , which provide additional flexibility in customizing the processing sequence for example, by applying For or ForEach loop iterations. It is also possible to further modify behavior of elements enclosed within a package by taking advantage of variables, whose values are assigned either prior or during its execution, variables also facilitate package reusability and simplify its transfer across different environments by providing a single location where configuration changes that need to be applied during such transfers are stored.
While each task has a unique role in covering a full spectrum of extraction, transformation, and loading activities, Data Flow Task stands out in regard to its significance and popularity. This dominance is reflected by its distinct visual representation in the Business Intelligence Development Studio interface, which we will describe in detail in our upcoming articles. This task represents the second category of package objects, known as Data Flow.
Its primary purpose is to manipulate data being transferred between its source and destination by applying any number of transformations such as aggregation, duplication, grouping, lookups, splits, merges, or samplings, to mention just a few. Definitions of source and destination data stores rely on Connection Managers , available to both Control Flow and Data Flow components, and facilitate access to a wide range of data formats including those defined using ADO.
If desired, it is possible to hide complexities of underlying storage simplifying its analysis by employing data source views. Flexible error and event handling , as well as transactional support increase resiliency and robustness of package execution. Troubleshooting can be considerably simplified by employing detailed and highly customizable debugging and logging mechanisms. The dual nature of SSIS packages is reflected by the similarly structured architecture of underlying system components.
More specifically, SSIS divides its responsibilities between the runtime engine which implements control flow functionality with such features as transactional support, debugging, event handling, or logging , and the data flow engine which facilitates activities defined within Data Flow Tasks , covering each of their stages, from extraction through transformation to loading.
In particular, from the package authoring perspective, Workgroup, Web, and Express Editions are limited to the interactive Import and Export Wizard with its basic choice of sources, transformations, and destinations, but without access to Business Intelligence Development Studio with its Designer interface. Both SQL Server Standard and Enterprise Editions offer fully functional Integrated Development Environment exposed via Business Intelligence Development Studio and its Designer interface and matching performance capabilities without artificially imposed throttling performance boundaries are imposed, however, by the 4 processor limit of Standard Edition and restrictions inherent to the operating system on which the SQL Server instance is hosted.
Either of them will let you experience the most interesting innovations introduced in the new platform, including the Data Profiling task facilitating capturing and analyzing data processed by SSIS packages or Cache Transform transformation, which delivers performance improvements during lookup operations.
In our next article, we will take a closer look at the initial setup and configuration of Integration Services in both SQL Server and R2 note that the latter is based on the November Community Technology Preview.

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. You can manage downlevel versions I currently use the version to manage , , R2 and instances except in rare compatibility scenarios e. I haven't tried to manage from but the SP2 release was able to do so.
If you ever end up on a download page that offers you a choice, you want either of these files, depending on whether your operating system is bit or bit:. Enterprise manager is a thing and all new versions have SSMS - starting from sql and up.
