Data in Domino is accessed and managed in Datasets and Projects.
A Domino Dataset is a collection of files. These files can be used and shared as a file system directory. A Dataset always reflects the most recent version of the data. You can modify the contents of the Dataset through the Domino application or through workload executions at any time.
A Domino Project is a container for your work. It includes the code, environment settings, datasets, and any other items needed to do your work. Your dataset collection can make up a part of a Domino Project. All items in a Domino Project can be accessed and shared. Each time your files change or code executes, your project is automatically tracked and revisioned.
