The most useful. standard UML diagrams are use case diagram, class diagram, sequence. It is beyond the scope of this introductory article to go into great detail. Instead, I will provide you with enough. Use case diagram. A use case illustrates a unit of functionality provided by the system. The. main purpose of the use case diagram is to help development teams. Use case diagrams generally show groups of use cases. To show a use case on a. To draw an. actor indicating a system user on a use case diagram, you draw a stick. Use simple. lines to depict relationships between actors and use cases, as shown in. Figure 1. Figure 1 Sample use case diagram. View image at full size. A use case diagram is typically used to communicate the high level. By looking at our use case. Figure 1, you can easily tell the functions that our example. This system lets the band manager view a sales statistics. Billboard 2. 00 report for the bands CDs. It also lets the. Billboard 2. 00 report. CD. The diagram also tells us that our system delivers. Billboard reports from an external system called Billboard Reporting. Service. In addition, the absence of use cases in this diagram shows what the system. For example, it does not provide a way for a band. Billboard 2. 00. i. Listen to Songs. from Billboard 2. This absence is not a trivial matter. With clear and. simple use case descriptions provided on such a diagram, a project sponsor. Class diagram.

Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements. The term architecture is also used metaphorically to refer to the design of organizations and other abstract concepts. Definitions and etymologyeditArchitecture Latin architectura, from the Greek arkhitekton architect, from chief and builder is both the process and the product of planning, designing, and constructing buildings and other physical structures. Architecture can mean A general term to describe buildings and other physical structures. The art and science of designingbuildings and some nonbuilding structures. The style of design and method of construction of buildings and other physical structures. A unifying or coherent form or structure5Knowledge of art, science, technology, and humanity. The design activity of the architect,4 from the macro level urban design, landscape architecture to the micro level construction details and furniture. The practice of the architect, where architecture means offering or rendering professional services in connection with the design and construction of buildings, or built environments. Theory of architectureeditHistoric treatiseseditThe earliest surviving written work on the subject of architecture is De architectura, by the Roman architect Vitruvius in the early 1st century AD. According to Vitruvius, a good building should satisfy the three principles of firmitas, utilitas, venustas,91. An equivalent in modern English would be Durability a building should stand up robustly and remain in good condition. Utility it should be suitable for the purposes for which it is used. Beauty it should be aesthetically pleasing. According to Vitruvius, the architect should strive to fulfill each of these three attributes as well as possible. Leon Battista Alberti, who elaborates on the ideas of Vitruvius in his treatise, De Re Aedificatoria, saw beauty primarily as a matter of proportion, although ornament also played a part. For Alberti, the rules of proportion were those that governed the idealised human figure, the Golden mean. The most important aspect of beauty was, therefore, an inherent part of an object, rather than something applied superficially, and was based on universal, recognisable truths. The notion of style in the arts was not developed until the 1. Vasari 1. 1 by the 1. Lives of the Most Excellent Painters, Sculptors, and Architects had been translated into Italian, French, Spanish, and English. In the early 1. 9th century, Augustus Welby Northmore Pugin wrote Contrasts 1. Gothic architecture, Pugin believed, was the only true Christian form of architecture. The 1. English art critic, John Ruskin, in his Seven Lamps of Architecture, published 1. Architecture was the art which so disposes and adorns the edifices raised by men. For Ruskin, the aesthetic was of overriding significance. His work goes on to state that a building is not truly a work of architecture unless it is in some way adorned. Cannon Technologies Lcr 5000 Manual Canon. For Ruskin, a well constructed, well proportioned, functional building needed string courses or rustication, at the very least. On the difference between the ideals of architecture and mere construction, the renowned 2. Le Corbusier wrote You employ stone, wood, and concrete, and with these materials you build houses and palaces that is construction. Ingenuity is at work. But suddenly you touch my heart, you do me good. I am happy and I say This is beautiful. That is Architecture. Le Corbusiers contemporary Ludwig Mies van der Rohe said Architecture starts when you carefully put two bricks together. There it begins. 1. Modern conceptseditThe notable 1. Louis Sullivan, promoted an overriding precept to architectural design Form follows function. While the notion that structural and aesthetic considerations should be entirely subject to functionality was met with both popularity and skepticism, it had the effect of introducing the concept of function in place of Vitruvius utility. Function came to be seen as encompassing all criteria of the use, perception and enjoyment of a building, not only practical but also aesthetic, psychological and cultural. Nunzia Rondanini stated, Through its aesthetic dimension architecture goes beyond the functional aspects that it has in common with other human sciences. Through its own particular way of expressing values, architecture can stimulate and influence social life without presuming that, in and of itself, it will promote social development. To restrict the meaning of architectural formalism to art for arts sake is not only reactionary it can also be a purposeless quest for perfection or originality which degrades form into a mere instrumentality. Gene Runner Primer Design. Among the philosophies that have influenced modern architects and their approach to building design are rationalism, empiricism, structuralism, poststructuralism, and phenomenology. In the late 2. 0th century a new concept was added to those included in the compass of both structure and function, the consideration of sustainability, hence sustainable architecture. To satisfy the contemporary ethos a building should be constructed in a manner which is environmentally friendly in terms of the production of its materials, its impact upon the natural and built environment of its surrounding area and the demands that it makes upon non sustainable power sources for heating, cooling, water and waste management and lighting. HistoryeditOrigins and vernacular architectureeditBuilding first evolved out of the dynamics between needs shelter, security, worship, etc. As human cultures developed and knowledge began to be formalized through oral traditions and practices, building became a craft, and architecture is the name given to the most highly formalized and respected versions of that craft. It is widely assumed that architectural success was the product of a process of trial and error, with progressively less trial and more replication as the results of the process proved increasingly satisfactory. What is termed vernacular architecture continues to be produced in many parts of the world. Indeed, vernacular buildings make up most of the built world that people experience every day. Early human settlements were mostly rural. Due to a surplus in production the economy began to expand resulting in urbanization thus creating urban areas which grew and evolved very rapidly in some cases, such as that of atal Hyk in Anatolia and Mohenjo Daro of the Indus Valley Civilization in modern day Pakistan. Ancient architectureeditIn many ancient civilizations, such as those of Egypt and Mesopotamia, architecture and urbanism reflected the constant engagement with the divine and the supernatural, and many ancient cultures resorted to monumentality in architecture to represent symbolically the political power of the ruler, the ruling elite, or the state itself.
