Design Decisions For Understanding Software Architecture

Like any other complex structure, software must be built on a solid foundation. Failing to see the big picture or consider key scenarios, failing to design for common problems, or failing to appreciate the long term consequences of key decisions can put your application at risk. Modern tools and platforms help to simplify the task of building applications, but they do not replace the need to design your application carefully, based on your specific scenarios and requirements. The risks exposed by poor architecture include software that is unstable, is unable to support existing or future business requirements, or is difficult to deploy or manage in a production environment. Software architecture must be distinguished from lower-level design (e.g., design of component internals and algorithms) and implementation.

While many practical issues interrupted due to Modernist language, Robert Venturi wrote a book of “Complexity and Contradiction in Architecture” and published in 1966. Book expresses the postmodernism and its rebellion to the purism of architecture. He respond to the quote of Mies van der Rohe “Less is more” as “Less is Bore” and discuss the architecture which should bow down to the complexities and contradictions. Architecture should be in touch with it in the creation of cities. After Modernisation, public spaces introduced into society and in the book of "The Society of the Spectacle” which is written by Guy Debord in 1967, criticize contemporary consumer culture and product fetishism which bring up the alienation of classes, mass media and homogenization of culture which

The logical architecture is the large-scale organization of software classes into packages, sub classes and layers. This is called logical architecture.

Enterprise Architecture is an all-inclusive approach to managing the complexity of IT from a business viewpoint. A framework is used to help describe how to create and use an EA, in a manner that delivers business benefit in a cost - effective way. Each framework has a different approach to adding value to the business. These criteria will identify the ways an enterprise architecture framework adds business value, how adaptability and flexibility effect the overall adoption of an enterprise architecture framework, how the deliverables contribute to the success of an enterprise architecture, how does each framework take a strategic approach to reduce complexity of enterprise architecture, and how the framework encompasses the Software Development Lifecycle.

When humans described architecture common synonyms that they might use would being design, building, planning, engineering, shape, color and more other words. My definition of architecture is by using the combination of art and math.

IT Architecture: Same as IS Vision, designing IT Architecture is also deals with information resource management for present and future use. The designing of IT Architecture should support the future IT needs. Cloud Computing is one of the best Solution for modular IT architecture now a days. Business Managers view also indicates the future here, as organization grows normally todays IT infrastructure should supports the tomorrows business needs and technology.

MVC architectural pattern is most extensively used by software architect designer, programmer and GUI developer while developing the user interactive applications. The MVC architectural pattern contains three types of architectural units or components: Model, View and Controller which actually separate the complete application logic to three logical units: business/entity (model), presentation (view) and control (controller). The model component contains business logic and application data, the view use to retrieve and show application data from/to user and the controller handle the user request/response through view and handle interaction between view and

In conclusion, it is clear that in the modern world of application and systems development it is difficult to control the entire infrastructure of the

Architecture is a long-term concern which takes significant amount of time, and this increased amount of time to market usually translates into reduced opportunity. One of the major reasons that software architectures are so often average is that architecture frequently takes a back seat to more mundane concerns such as cost, time-to-market, and programmer skill. Thus, business forces tend not to allow

In general, it is a web-based software that the architecture consists of user interaction, logical operation, and data storage. And in most cases, software development need teamwork which means lots developer with different background work together for one goal. A proper working process would be helpful to successfully complete the development.

In this research paper, we will analyze look at the context of enterprise architecture, the history of enterprise architecture, and we will look at two popular enterprise architectures, the Zachman framework and TOGAF.

Enterprise Architecture is a relatively new field which has, in recent years, firmly implanted itself as an increasingly integral facet within information technology (IT) companies. It is meant to provide structure to the company’s IT department through strategic organization of the department’s assets. More specifically, the concept is meant to manage an enterprise’s IT resources in an effort to streamline and organize the laborious process associated with large-scale IT projects and the chaotic environment they foment (Harrell, 2011, p. xii). This is done through a streamlining process that “establishes the organization-wide roadmap to achieve an organization’s mission through optimal performance of its core business processes within an efficient [IT] environment” (Schekkermann, 2006, p. i). The practice effectively builds a schematic for the company and its procedures as it strives to fulfill its operational endeavors.

In order to better understand the similarities and differences between software architecture and building architecture one needs to know what software is. According to "Software Engineering Institute" (2015), "The software architecture of a program

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
