An user defined environment variable is a place holder to store a value that can used in the entire project.

Parameter set is new time saving feature added in DataStage 8x. Parameter set is set of job parameters that are likely to be reused in other jobs. These parameter sets are stored as files in the WebSphere DataStage server installation directory and are also available in the Repository to use in your job designs.
