Summary
The Unified Modeling Language (UML) is a standard graphical language used for specifying, visualizing, constructing, and documenting the artifacts of software systems as well as non-software systems, and for business modeling purposes. Being a standard language for writing software blueprints, the UML represents a collection of best engineering practices that has proven successful in the modeling of large and complex systems…

The UML has gained substantial industry support from various organizations through the UML Partners Consortium and has been approved by the Object Management Group (OMG) as a criterion. The UML provides the rules and the vocabulary for conceptual and physical representation of a system. Additionally, UML renders the guidelines to create and read well-formed models of systems. Employing UML, application architects and programmers can make a blueprint of a project that visualizes the relationship between elements of software, which in turn makes the actual development process of the software easier. The originator of UML, the Rational Rose from Rational Software, is the most popular visual modeling tool. The UML is a modeling language that focuses on capturing, communicating and levering knowledge. However, the UML is not restricted to modeling software systems; it can also be utilized for modeling non-software systems. It helps in visualizing a system in that it can be used to visually depict a system before it is deployed. It helps in specifying systems in that it addresses "what" is required of system, and "how" the system may be deployed. By constructing a system, UML applies for guiding the realization of a system similar to a "blueprint", and by documenting a system UML applies for capturing knowledge about a system throughout its development (Xpdian.com, 2009).
Relationships in UML: 1. Dependency: It is a semantic relationship between two things in which a change to one thing (independent element) may affect the semantics of another thing (dependent element). Graphically, a dependency is rendered as a directed dashed line, including labels. 2. Association: It is a structural relationship that describes a asset of links, a link being connection among objects. Graphically, an association is rendered as a directed solid line, including a label, and often containing adornments like multiplicity, role names, etc. 3. Generalization: It is a specialization/generalization relationship in which objects of the specialized element (child) can be substituted for objects of the generalized element (parent). Graphically, a generalization is rendered as a solid line with a hollow arrowhead pointing to the parent. 4. Realization: It is a semantic relationship between classifiers, in which one classifier defines a contract that another classifier guarantees to execute. This relationship is seen in two places, between interfaces and the classes or components that realize them, and between use cases and collaborations that realize them. Graphically, a realization is rendered as a cross between generalization and a dependency relationship (Xpdian.com, 2009).
UML defines nine types of diagrams:
Class Diagrams: Class diagrams are the backbone of every object oriented method, including UML, and are most common diagrams found in modeling object oriented systems. Class diagrams address the static view/ structure of a system. Object Diagrams: Object diagrams represent static snapshots of instances of the things found in class diagrams. In other words, these diagrams describe the static structure of a system at a particular time. They are designed to test class diagrams for accuracy.

...document, specify and modify the elements of an object oriented system under enhancement.. J. Object Management Group (OMG) is an association of several computer design and system developers. The formation of the OMG targeted the setting of conventional standards for disturbed object oriented systems. Currently, the organization concerns with different aspects of modeling such as business processes, systems and programs. OMG attempts to avert vague standards that cannot be implementable or have never been implemented. Object Management Group also provides other standards basing on modeling principles. Apart from the UML, OMG also involves in other modeling operations. Meta Object Facility (MOF) is another specification employed in OMG....

... Usability study on a web page – UML Designing a web page is a that needs ample time to come out with the best approach in the web. A web page needs an amply designed form to give it the best approach. To begin with, there are acceptable standards that need to be observed. The initial stage in designing a web is beginning with the home page. The home page is the opening page on the web. The home page is the initial step that displays what the web page holds. A home page is the first page that displays the basic needs of the web. For instance, a web page that is well designed to display the home page gives the viewers an attractive side that is needed by the viewers. A web page that displays the initial steps to the viewers gives... Usability...

How UML and Agile Development fit together

...?How UML and Agile Development fit together What is software architecture and how is it different from other forms of design? Software architecture is the designing and implementation of high-level structure of software. While other forms of software design are largely about algorithm and data structures, software architecture is mainly about elements, forms, and rationale of the design at a larger scale (Clements et al. 66). Software architecture comes about through assembly of architectural elements in well-chosen forms to satisfy the functionality and performance needs of system. It also satisfies other non-functional system requirement including scalability, portability, reliability, and availability of software. 2. How can software...

System Analysis and Design

... centered in our case it would not be very useful since the objects, actors, events and relationships can be traced from the narrative thus UML becomes the preferred case tool. With the use cases, UML enables us to study existing objects to see if they can be reused or adapted for new uses, and to define new or modified objects that will be combined with existing objects into a useful business computing application. This identification objects within the systems environment, and the relationships between those objects makes the drawing of the diagrams much faster and easier. For example, in our case we identify the objects (member), their data attributes (member no, firstname), associated behavior such as booking for a tennis court...

...e order of progression of actions is from the top to the bottom. Thus, the action that is closer to the top occurs earlier than the one occurring at the bottom. A message between two objects is by an arrowhead moving from the sending object to the receiving object. For instance, the first message in the above diagram is from the withdrawal to the screen. The thin vertical rectangle in the diagram shows that an object is executing. A dotted line from the receiver to the sending object displays a return message. UML allows us to omit the return message arrows to do away with untidiness. As a result, the diagrams are better readable than if they were included. It is also in order to display parameters in the message (Zandstra, 2014).The...
