This defines the area where uniqueness is guaranteed, such as a single database (local scope) or a global network (global scope). Common Types and Generation Methods A Unique Identifier (UID) is a numeric or

UIDs are generated through various strategies depending on the scale and security needs of the application: Common Types and Generation Methods UIDs are generated
