UML Diagrams used to represent the development view include the Package diagram and the Component diagram. Development view: The development view (aka the implementation view) illustrates a system from a programmer's perspective and is concerned with software management.UML diagrams to represent process view include the sequence diagram, communication diagram, activity diagram. The process view addresses concurrency, distribution, integrator, performance, and scalability, etc. Process view: The process view deals with the dynamic aspects of the system, explains the system processes and how they communicate, and focuses on the run time behavior of the system.UML diagrams are used to represent the logical view, and include class diagrams, and state diagrams. Logical view: The logical view is concerned with the functionality that the system provides to end-users.In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. The four views of the model are logical, development, process and physical view. The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers. It helps to specify whether a parameter is an input, an output, or both.View model in software architecture Illustration of the 4+1 Architectural View Model.Ĥ+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". In class diagrams, parameter directionality refers to the indication of the flow of information between classes through method parameters. ~ for package or default visibility (visible to classes in the same package).# for protected (visible to subclasses).- for private (visible only within the class).Visibility notations indicate the access level of attributes and methods.They are listed in the third compartment of the class box and include the visibility (e.g., public, private), return type, and parameters of each method. Methods, also known as functions or operations, represent the behavior or functionality of the class.They are listed in the second compartment of the class box and often include the visibility (e.g., public, private) and the data type of each attribute. Attributes, also known as properties or fields, represent the data members of the class.The name of the class is typically written in the top compartment of the class box and is centered and bold.UML Class NotationĬlass notation is a graphical representation used to depict classes and their relationships in object-oriented modeling. ![]() The attributes represent the characteristics or properties of the object, while the methods define the behaviors or actions that the object can perform. Objects are instances of classes, and each class defines a set of attributes (data members) and methods (functions or procedures) that the objects created from that class will possess. In object-oriented programming (OOP), a class is a blueprint or template for creating objects.
