Web software complexity of an application can be minimized using various UML tools. UML-based web engineering aims at offering a UML profile that matches the needs of web development better. The following are examples: Representation of web applications using a set of models Web app use case model; Web app implementation model
A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...
For agile development, a requirement model of many UML diagrams depicting use cases plus some textual descriptions, notes, or use case briefs would be very lightweight and just enough for small or easy project use. As good complements to use case texts, the visual diagram representations of use cases are also effective facilitating tools for ...
Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
An artifact is one of many kinds of tangible by-products produced during the development of software. Some artifacts (e.g., use cases, class diagrams, requirements and design documents) help describe the function, architecture, and design of software. Other artifacts are concerned with the process of development itself—such as project plans ...
Use case analysis is a technique used to identify the requirements of a system (normally associated with software/process design) and the information used to both define processes used and classes (which are a collection of actors and processes) which will be used both in the use case diagram and the overall use case in the development or redesign of a software system or program.
4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.
Use case diagrams are used to identify the actor (users or other systems) and the processes they perform. System sequence diagram : A system sequence diagram (SSD) is a picture that shows, for a particular scenario of a use case, the events that external actors generate, their order, and possible inter-system events.
