The Unified Modeling Language ( Uml ) - 1386 Words

The Unified Modeling Language (UML), with its fourteen various diagram types, is a standard notation for the modeling of real-world objects as a first step in developing an object-oriented design method. Although a lot of semantics in the UML, we can widely describe in the more details the system that will be developed, but we cannot make sure the correctness and consistency of the designed model. Therefore, it is important to reduce the error from verifying user model in the early phase, When those errors are discovered early in the design process it is easier and more cost helpful to fix than if they were discovered at a later phase. The issue of consistency and inconsistency have appeared since its infancy of the software development. These problems are bigger still in UML software development, and are mainly reason of the presence of multiple-views (models) for the same system, and It can contain potentially contradictory system specifications. In other meaning, the UML diagrams describing a software must be consistent because inconsistencies between all diagrams in UML It will be the source of the increase defects and errors in the software systems. It is therefore important that these inconsistencies be detected in the system, analyzed and hopefully fixed before implementing it. Without consistency analysis, it would be hard to evolve the model and ensure that the collaborative effort is coherent.

It is a way to envision the system architecture in the form of a diagram.

A class diagram 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. It is used both for generalconceptual modelling of the systematics of the application, and for detailed modeling translating the models into programming code. For data modeling class diagrams can also be used.The classes in a class diagramRead MoreUnified Modeling Language ( Uml ) For Database Systems And Computer Applications2057 Words   |  9 PagesUnified Modeling Language (UML) for Database Systems and Computer Applications Abstract This paper shows the ideas of database frameworks and also the outline of the utilization of Brought together Demonstrating Dialect (UML) as a standard documentation of true protests in creating item situated configuration procedure for PC applications.

Automate the measure from a UML perspective and the other to add an objective measure of complexity to a standard measure in COSMIC-FFP in order to reach a higher level of confidence with those measures.
