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.

A UML link is run-time relationship between instances of classifiers, while a dependency is a model-time relationship between definitions. A typical uni-directional link requires the one instance to know about, and thus depend, upon the other, but this is not required. A uni-directional link only requires the possibility of navigation not ...
Realization - Realization shows the relationship between an Interface and the class that provides the implementation for the interface. Reference-Request - The input to the system for finding the related abstracts from different operations (Add, Del, Mod, Inq.). Request could be for only one for every operation; Response - The output of the ...

A UML Component with provided and required interfaces. A component [1] in the Unified Modeling Language represents a modular part of a system that encapsulates the state and behavior of a number of classifiers. Its behavior is defined in terms of provided and required interfaces, [2] is self-contained, and substitutable.
This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality. Sequence diagrams are typically associated with use case realizations in the 4+1 architectural view model of the system under development. Sequence diagrams are sometimes called event diagrams or event scenarios.
Interaction Overview Diagram [1] is one of the fourteen "nominative" types of diagrams [2] of the Unified Modeling Language (UML), which can picture a control flow with nodes that can contain interaction diagrams. The interaction overview diagram is similar to the activity diagram, in that both visualize a
