Detailed explanation-1: -In general, associations are relationship types involving two or more entity types. An association between two entity types is called binary, while associations between more than two entity types are called n-ary (with the special case of 3-ary associations called ternary).
Detailed explanation-2: -Attribute. A characteristic or trait of an entity type that describes the entity, for example, the Person entity type has the Date of Birth attribute.
Detailed explanation-3: -The relationship between an entity type and an entity set is analogous to the relationship between a row and a table in a relational database: Like a row, an entity type describes data structure, and, like a table, an entity set contains instances of a given structure.
