Each use case realization will define the physical design in terms of classes and collaborating objects which support the use case. Therefore, each use case realization typically is made up of a class diagram and a number of interaction diagrams, most commonly sequence diagrams, showing the collaboration or interaction between physical objects.
Use case analysis is a technique used to identify and elicit the functional requirements of a system. It is used in software intensive systems and process design.
A use-case realization represents how a use case will be implemented in terms of collaborating objects. This artifact can take various forms. It can include, for example, a textual description (a document), class diagrams of participating classes and subsystems, and interaction diagrams (communication and sequence diagrams) that illustrate the flow of interactions between class and subsystem ...
A use-case realization represents how a use case will be implemented in terms of collaborating objects. The realizations reside within the design. By walking through a design exercise of showing how the design elements will perform the use case, the team gets confirmation that the design is robust enough to perform the required behavior. The realization can take various forms. It may include ...
Case realization refers to the development process of a use case from its initial identification to implementation, involving a complete iteration through all development activities. It involves analyzing each identified use case separately to identify the classes required by it, which are grouped into collaborations and sometimes packages, leading to the compilation of a unified class diagram ...
A use-case realization represents the design perspective of a use case. It is an organization model element used to group a number of artifacts related to the design of a use case, such as class diagrams of participating classes and subsystems, and sequence diagrams which illustrate the flow of events of a use case, performed by a set of class ...
Use Case Realizations A use case realization describes how a particular use case is realized in terms of collaborating objects.
Use cases once specified can be denoted both textual and visual representation (i.e. use case diagram). A key concept of use case modeling is that it helps us design a system from the end user's perspective. It is an effective technique for communicating system behavior in the user's terms by specifying all externally visible system behavior.
17.1 Use-Case Realizations " [RUP]. More pre-cisely, a designer can describe the design of one or more scenarios of a use case; each of these is called a use-case r alization. Use-case realization is a UP term or concept used to remind us of the connection between the requirements expressed as use cases, and the object design that satisfies ...
Use-Case Realizations · A use-case realization describes how a particular use case is realized within the design model, in terms of collaborating objects · Designer describes the design of one or more scenarios of a use-case: each is called a use-case realization. · UML interaction diagrams illustrate use-case realizations.
