The objects interact with each other indirectly through a mediator object that controls and coordinates the interaction. This makes the objects loosely coupled. They only refer to and know about their mediator object and have no explicit knowledge of each other. See also the UML class and sequence diagram below.
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.
The Type 052Ds are fitted with the four-panel Type 346A (NATO reporting name: Dragon Eye) active electronically scanned array (AESA) radar system. [7] Chinese media informally calls the Type 052D the Chinese Aegis (Chinese: 中华神盾; pinyin: Zhōnghuá Shéndùn), portraying it as a peer of contemporary United States Navy ships equipped with the Aegis Combat System.

A ship class is a group of ships of a similar design. [1] This is distinct from a ship type, [1] which might reflect a similarity of tonnage or intended use. For example, USS Carl Vinson is a nuclear aircraft carrier (ship type) of the Nimitz class (ship class). In the course of building a class of ships, design changes might be implemented.
An object graph is a view of an object system at a particular point in time. Unlike a normal data model such as a Unified Modeling Language (UML) class diagram, which details the relationships between classes, the object graph relates their instances. Object diagrams are subsets of the overall object graph.
The Type 053H3 (NATO reporting name: Jiangwei II) is a class of Chinese frigates that entered service with the People's Liberation Army Navy Surface Force in the 1990s and 2000s.
