I am new to SharePoint. I am interested in setting it up to manage projects but am a little confused by the nomenclature SP uses.
Many of my projects are relatively small and can last less than a day. Some are larger and may take weeks. I am also interested in maintaining a parent/child relationship where I can have one project with many child projects. I also might have hundreds of active projects running at the same time.
With that as the base, would a project be a subsite? an app? or something else? Can anybody clarify the best structure for my use case?
