(DTS) Data Transformation Services is a set of objects and utilities to allow the
- automation of extract,
- transform and
- load operations
to or from a database.
The objects are DTS packages and their components, and the utilities are called DTS tools.
DTS was included with earlier versions of Microsoft SQL Server, and was almost always used with SQL Server databases, although it could be used independently with other databases.
DTS allows data to be transformed and loaded from heterogeneous sources using OLE DB, ODBC, or text files, into any supported database.
DTS can also allow automation of data import or transformation on a scheduled basis, and can perform additional functions such as FTPing files and executing external programs.
Furthermore, DTS provides an alternative method of version control and backup for packages when used in conjunction with a version control system, such as Microsoft Visual SourceSafe.
DTS has been superseded by SQL Server Integration Services
in later releases of Microsoft SQL Server though there was some backwards compatibility and ability to run
DTS packages in the new SSIS for a time.
