One of the SQL Server 2005 Beta 2 features that has undergone considerable architectural, functional, and interface changes, compared with its earlier versions, deals with extraction, transformation, and loading (also known as simply ETL) of data. (In other words, allowing you to move data between a variety of stores and to modify it in the process, according to your arbitrary requirements). While in SQL Server 7.0 and 2000, such capabilities have been provided by Data Transformation Services (DTS in short), Microsoft decided that the degree of modifications introduced in the new version justified re-branding it, hence its rearchitectured and significantly improved implementation has been introduced under the new name of SQL Server Integration Services (SSIS).
