Unified Modeling Language (UML) is a standardized modeling language used in object-oriented software engineering. There are several types of relationships used in UML, including:

1. Association: This is a structural relationship that represents a binary relationship between two classes. It shows how the objects in the classes relate to each other.

2. Aggregation: This is a special type of association that represents a whole-part relationship. It shows how a complex object can be broken down into simpler ones.

3. Composition: This is a stronger form of aggregation where the part cannot exist without the whole. If the whole is deleted, the part is also deleted.

4. Dependency: This is a relationship where a change in one element (the supplier) may affect another element (the client), but not necessarily the other way around.

5. Generalization: This is a relationship in which one model element (the child) is based on another model element (the parent). It's essentially an "is-a" relationship.

6. Realization: This is a relationship between two model elements, in which one model element (the interface) specifies some behavior that the other model element (the class) guarantees to carry out.

Each of these relationships provides a different way to visualize and understand the connections between objects and classes in a software system.
