Detailed explanation-1: -In UML diagrams, an interface realization relationship is a specialized type of implementation relationship between a classifier and a provided interface. The interface realization relationship specifies that the realizing classifier must conform to the contract that the provided interface specifies.

Detailed explanation-2: -A relationship is a connection among things. In object-oriented modeling, the three most important relationships are dependencies, generalizations, and associations. Graphically, a relationship is rendered as a path, with different kinds of lines used to distinguish the kinds of relationships.

Detailed explanation-3: -An association relationship can be represented as one-to-one, one-to-many, or many-to-many (also known as cardinality). Essentially, an association relationship between two or more objects denotes a path of communication (also called a link) between them so that one object can send a message to another.
