Dummy dataset is used when you donot need to specify a ddname in the JCL. Nothing can be stored in it. Simply Null or Dummy.

Temporary dataset is a dataset in which you can store data on it and this dataset exists till the end of job execution after which it will be uncatalogued automatically.

semman - Regarding DUMMY, I think it is the oposite: You need to supply DDNAME, but you don't want to associate any dataset with it.

Another difference can be of memory space. Dummy doesn't involve any but Temporary does.
