SQL Server Integration Services (SSIS) is a Microsoft SQL Server component designed for data migration tasks and workflow applications, featuring capabilities for data extraction, transformation, and loading (ETL). It serves as a fast and flexible data warehousing tool, automating database maintenance and updates to multidimensional cube data. SSIS, released with SQL Server 2005, replaces the older Data Transformation Services (DTS) and is available only in the Standard, Business Intelligence, and Enterprise editions.
