GENERAL GEOLOGY

Detailed explanation-1: -A UML diagram is a diagram based on the UML (Unified Modeling Language) with the purpose of visually representing a system along with its main actors, roles, actions, artifacts or classes, in order to better understand, alter, maintain, or document information about the system.

Detailed explanation-2: -A communication diagram (called collaboration in previous version of UML) without messages is also known as an object diagram, and the relationships between objects are called links. An object diagram must be a valid instantiation of a static class diagram.

Detailed explanation-3: -Communication diagram Communication diagrams, which used to be called collaboration diagrams, show how objects relate to each other. They model the way objects associate and connect through messages within an architectural design of a system.

Detailed explanation-4: -"An object diagram is a graph of instances, including objects and data values. A static object diagram is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in time. The use of object diagrams is fairly limited, namely to show examples of data structure."
