A study is a construct that helps you organize and track the data sets and settings associated with a particular study or project. Specifically, a study consists of a Study Name associated with collections of zero or more data sets and zero or more settings, possibly located in various folders.Using a study greatly simplifies browsing for an input data set or a setting to load. Dialogs initially display all data sets and settings associated with the selected study, even if they are saved to different folders. You are prompted for the correct type of data set to choose, whether it is a wide or tall data set (see Tall and Wide Data Sets), an Annotation Data Set, or an Experimental Design Data Set (EDDS). You can easily navigate to a data set not yet associated with the study and associate it for future data set selection. When you run a process with a study selected, the study is automatically updated with the output data sets created and the setting that is run. A metadata folder for each study provides a central location for tracking all the processes that have been run, in both the _processinfo.sas7bdat data set and the StudyLog.txt file.
