INTRODUCTION The purpose of this essay is about using a real example to show the role of software architecture in a software project, also describing its role in the project and finally evaluating if the software architect played his or her role effectively. Firstly what is software architecture and who is a software architect? There have been numerous defined of what software architecture is but as defined by Mary Garlan and David Shaw (1993) as a level of design that involves four(4) major component which are the description of elements from which the system was built, the interaction among those element, also the pattern that guides the system composition and finally the constraint on these pattern. Software architecture is a list …show more content…
Architecture can provide basis of throwaway prototype. Architecture enables a system’s driving quality attributes. Architecture is responsible for defining constraints on subsequent implementation. With the above list of important it shows how and why software architecture is important in carrying out a project Before beginning the designing of a software system, an architects needs to get the key requirement that affect the important structure of the system. The architectural drivers have great influence on the early design decisions the architect makes. In software architecture there are five major drivers which are as follows: the design purpose, quality attributes, primary functionality, architectural concerns and lastly, constraints. The various drivers listed above have been taken into consideration because the roles are critical to the success of the system being designed. Design purpose: Firstly, system developers need to clearly know the purpose of the design that they want to achieve. Developers need to ask questions like, when and why they are doing the architecture design and also the major business goals of the organisation at that point in …show more content…
These abilities play vital role in other to put a working system to use (Bass, Clements, & Kazman, 2012). When designing software architecture, primary functionality need to be put into consideration because it is a functionality that is critical to achieve the business objective which inspires the development of the system. Primary functionality indicate high level of technicality, which without an architect been present, users cannot use the system. In designing an architecture, thoughts of functionality allocation amongst element of the system is very important because this increases reusability and modifiability. Moving on, INSTAGRAM will be used as an example to show the role of software architecture in completing this project. Instagram is an easy to use mobile application which was formerly just a web application that is used to capture, upload and edit pictures and videos either with tablet computers or smart phones. Users can share their creation on both Instagram and other various social media websites such as Facebook (which are currently the parent company of Instagram) Facebook bought Instagram since April 2012 and they still retain its attributes (Ochs,
Software design and development is a field that requires various skills and abilities. Companies engaged in the development of software should provide an inclusive work environment where the different strengths of their employees are recognised, utilised and respected. Software development involves far more than programming skills. Personnel are required with strong communication, teamwork, attention to detail, creativity, design and problem-solving skills. Different personnel will possess these skills in varying proportions. It is the job of management to foster and encourage the development and enhancement of skills in the workplace.
Stage 3 involves creating an Architectural Model version of the whole system including sub systems. A Viewpoint Hierarchy shows a skeleton version of the system which can be ins...
In addition, the app offers users an ability to customize the image using filters. The purpose of the filters is to turn a mobile photo into an artistic-looking image. The name was derived from the combination of “instant camera” and telegram. According to an article published by Mikaela Rakos, Instagram started with “one million monthly users” (Rakos 2014). In April of 2012, the company reached 30 million users. As a result, Facebook noticed the growth and bought the app for one billion dollars (on April 9, 2012). From that point on, the usage of Instagram has gone up exponentially, reaching 150 million users in 2013. Instagram’s growth is largely due to the Facebook purchase. The company was listed in Time Magazine as “one of the top 50 apps for Android” and a report by Global Web index found that Instagram was the fastest growing social
are used as the integral components of the architectural design, this reflecting a conceptual cohesion that is missed in previous architecture.
Architecture is functional in that it provides one of the three necessities of man (shelter)
The system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.
Simon Unwin, the author of the book ‘Analysing Architecture’ says that the ‘the purpose of architecture is to design buildings’ is an unsatisfactory definition because the definition limits architecture to just the design of buildings. He feels that architecture involves more than just designing buildings. He also believes that the definition fails to explain the real purpose of architecture and transfers the problem of comprehending the word ‘architecture’ to the word ‘building’. This definition doesn’t go in-depth to analyze and understand the essence of architecture in our everyday lives. It fails to relate human life and needs to the buildings built.
Component Based Architecture creates a system that is easily extensible, promotes software reuse and intuitively understandable. A component often relates to an object in Object Orientated Programming. The RUP provides a systematic way to build this kind of system, focusing on producing an early executable architecture before committing full resources on a project.
The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
Instagram is one of the best and prominent marketing platform that help businesses to spread out their word across the world with the means of pictures. Everyday more than 75 million pics/posts are uploaded in Instagram, and that 's why it has turned as a world of attention and traffic as well. If used Instagram smartly and savvy, it can help you reap attention which can be effectively used and exploited for the business.
There are many different ways to define an architecture as they can take many forms, including logical views, scenarios (or sequence diagrams), physical views and deployment views. Each view provides a specific type of information within the diagram and is directed to a certain audience, including Web architects, data architects, application architects and end users.
The input and output sections allow the computer to receive and send data, respectively. Different hardware architectures are required because of the specialized needs of systems and users. One user may need a system to display graphics extremely fast, while another system may have to be optimized for searching a database or conserving battery power in a laptop computer. In addition to the hardware design, the architects must consider what software programs will operate the system.
Times have changed since days of Vitruvius, the inevitable advancement in technology, rapid global population increase and an ever developing awareness of the sustainability of our environment have forced the architect into different positions in the project team Thus it can be said that the external forces that shape the environment that an architect works in does so by manipulating the relationship between the skills required to practice; the scope of expertise and the depth of knowledge. Fig. 3 indicates a diagrammatic timeline representing the changing roles of the architect over the various time periods with respect to the scope and depth of
Architectural engineers help plan how a building is constructed so that it will look and function the way it was designed. Their work includes preparing building design and construction documents, cost estimating and construction-related projects. Architectural engineers should be creative, inquisitive, analytical, and detail-oriented. They should be able to work as part of a team and be able to communicate well, both orally and in writing.
