In software engineering, a class diagram [1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
Class diagram - a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes and the relationships between the classes. Classifier - a category of UML elements that have some common features, such as attributes or methods.
UML logo. The unified modeling language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. [1] UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure ...
A classifier is an abstract metaclass classification concept that serves as a mechanism to show interfaces, classes, datatypes and components.. A classifier describes a set of instances that have common behavioral and structural features (operations and attributes, respectively).

A sample UML class and sequence diagram for the facade design pattern In this UML class diagram , the Client class doesn't access the subsystem classes directly. Instead, the Client works through a Facade class that implements a simple interface in terms of (by delegating to) the subsystem classes ( Class1 , Class2 , and Class3 ).
The Sequence diagram of UML Overview. In software engineering, a sequence diagram [1] shows process interactions arranged in time sequence. This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality.
