For example – Name of a person that is normally subdivided into First name, Middle name, and Last name is a composite attribute. The composite and Multi-valued attributes may be grouped into constitute “Complex ones”. The paren-thesis () are used for showing grouping of components of composite attributes. The braces {} are used for showing the multi-valued attributes.
