SQL Server Integration Services or the SSIS component available with the SQL Server product can facilitate a large range of data migration services for the user. The SSIS 2012 component will take care of a wide diversity of data integration as well as workflow automation applications. It will facilitate setting up data warehouses for ETL (or data extraction, transformation and loading) applications. The SSIS component is useful for automatic maintenance and update of OLAP cubes (and hyper-cubes). OLAP, as we know is an on-line analytic processing of 3 or more dimensional data. OLAP processes can help users underlying data patterns and insights. Due to the large volume of these multi-dimensional data, patterns may not be visible easily otherwise.

Data migrations are an integral part of upgrades to enterprise systems. This may involve transfer of data from one storage type to another, format changes or moving of an application to the next generation of computing equipment. This SSIS component could be a huge facilitator in all such cases. Tools available in SQL Server Integration Services let you the migration to be completed automatically and without errors. Many different situations can call for such migrations. Technological changes, server or the storage technology upgrade or a simple reason like the need for relocating a data center. Services available in SSIS 2012 can be very useful in any such situation.

Data migration, typically, involves the so called D-T-L or the data extraction, transformation (if, and as required) and then loading into the new system. SQL server tool SSIS can be useful in each of these stages. There is a data verification stage that is mandatory establishing that the data, as loaded, is error free. Tools available in SSIS 2012 can be useful for these tasks. In a typical migration process, each of these stages may have to be repeated. It may be essential to run the legacy as well as the new system simultaneously for some time until the SSIS 2012 can demonstrate that the process has been successful. The SQL Server Integration Services tool is now available only with the standard, BI and enterprise editions from the version 7 (1998) release. It used to be available for all editions earlier. One of the most useful features on the SSIS must be the import/export wizard. It is a simple transfer tool for transfers that do not involve any transformation. The SQL Server Integration Services can handle multiple source and destination types. On the development front, the SSIS provides BI development studio or BIDS. This is based on Microsoft’s VB studio. Developers can develop and debug package with drag and drop ease of the VB like features. A package defines a workflow and can have many elements. BIDS have since been updated in SSIS as the SQL Server data tool-Business intelligence (SSDT-BI). Connectors, event handlers, parameters, precedence constraints, takes, and variables are some features that are useful in working with the SQL Server Integration Services (SSIS). There are some additional tools in the integration services.

Executing packages from command prompt and setting up of configurations for packages to reused are possible. Storage of a package and retrieval are possible with these tools.
