DTS is available in SQL 2000. It stands for Data Transformation Services. It is (or was) a use fuel tool for importing data from one source to another. Like from an Access, SQL, Oracle, PHP DB, or a flat file or spreadsheet into a SQL Database - or whatever. Once a DTS package is created, you could then create a job that will automatically run the package on a set schedule - for example you may want to import new records from one table to another table every night. But DTS isn't in SQL 2005 - but you can still use old DTS packages with 2005. The new technology is SQL Server Integration Services (SSIS).
