A stereotype is a new kind of model element with the same structure as an existing element, but with additional constraints, a different interpretation and icon, and different treatment by code generators and other back-end tools. A stereotype defines a set of tagged values. A tagged value is a userdefined attribute that applies to model elements themselves, rather than objects in the run-time system. For example, tagged values may indicate project management information, code generator guidance, and domain-specific information.<\/p>\n

A constraint is a well-formedness condition expressed as a text string in some constraint language, such as a programming language, special constraint language, or natural language. UML includes a constraint language called OCL. A profile is a set of stereotypes and constraints for a particular purpose that can be applied to user packages. Profiles can be developed for particular purposes and stored in libraries for use in user models. As with any extensibility mechanism, these mechanisms must be used with care because of the risk of producing a private dialect unintelligible to others.<\/p>\n

But they can avoid the need for more radical changes. UML – Architecture Any real world system is used by different users. The users can be developers, testers, business people, analysts and many more. So before designing a system the architecture is made with different perspectives in mind. The most important part is to visualize the system from different viewer\u2019s perspective. The better we understand the better we make the system. UML plays an important role in defining different perspectives of a system. These perspectives are: \u2022 Design \u2022 Implementation \u2022 Process \u2022 Deployment And the center is the Use Case view which connects all these four.<\/p>\n

A Use case represents the functionality of the system. So the other perspectives are connected with use case. \u2022 Design of a system consists of classes, interfaces and collaboration. UML provides class diagram, object diagram to support this. \u2022 Implementation defines the components assembled together to make a complete physical system. UML Stereotype is an over-generalized belief about a particular category of people Core Concepts in Computer Science: Database Management Systems component diagram is used to support implementation perspective.<\/p>\n

\u2022 Process defines the flow of the system. So the same elements as used in Design are also used to support this perspective. \u2022 Deployment represents the physical nodes of the system that forms the hardware. UML deployment diagram is used to support this perspective. UML – Modeling Types It is very important to distinguish between the UML models.<\/p>\n

Different diagrams are used for different type of UML modeling.<\/p>\n
