CS-7014 Week 5 - Assignment: Main Task: Explain Problematic Implementation Introduction Architectural design refers to the mechanisms that are used to frame the structure of a computer-based system. Proper architectural designs enable a computer system to develop its compatibility feature. Compatibility in this sense refers to the manner in which the computer- based systems fulfill the needs of the users (Denford, O’Neill & Leaney, 2003). Transform characteristics can be considered as one of the methods to develop an efficient computer system (Losavio, Chirinos, Lévy & Ramdane-Cherif, 2003). Emphasizing the issue, the essay aimed at describing the architectural design of a computer-based system, which possesses distinct transform characteristics. …show more content…
Moreover, the transform characteristics of the architectural design are valid if these are simpler to understand. This is because a linear model is used that reflects about the generation of one command in the flow model after providing instructions in a sequential manner. With respect to the data flow diagram illustrated above, it can be determined that a maximum of two commands is generated within a computer-based system. For instance, the transform characteristics often produce two results, namely ‘produce valid results’ and ‘generate message of invalidity’ when the passwords inserted by the users do not match with those that are installed in a computer-based system (Pressman, …show more content…
For instance, the hackers can easily break the password, which has been provided in the system and start functioning without taking authorization of the respective users. These hackers can retrieve tacit and confidential information from a computer-based system, leading towards severe loss for the authorized users (James, n.d.). Structuring Requirements The structuring requirement of the software architecture is associated with determining the need of designing the transform characteristics. If the users use passwords to prevent leakage of vital data, then the transform process might become more complex. Moreover, another structuring requirement of the software architecture includes the support of competent software engineers who can effectively design the transform process as per the expectation level (Vie, n.d). Conclusion Architectural design is important to devise a proper computer-based system and allowing it to function properly. The data flow diagram designed for this essay eventually portrayed the ways through which architectural design can be used to design transform characteristics, safeguarding the computer system by incorporating and using relevant

Security architecture is a major component and part of a system’s architecture and is usually designed to provide important guidance during the development of the system. It usually outlines the assurance level required and in the process outlines the possible impacts that this level of security might have on the development process of the actual system. Since security is a major component for the success of any given business unit, it is necessary to have a fully functional and operative security system that meets all the necessary requirements for any organization. Some leading business firms are usually faced with the task of achieving and maintaining high security measures and methods. SecureTek one of the leading provider of security solutions is faced with the challenge of redesigning their security architecture to assure security to the data and the other firm’s valuable assets as well as ensuring security to their customers and employees who encounter risky situations when visiting this business unit.

This section provides an overview and a brief description of the system design. The system structure, the database design, and the user interface
The first class stereotype is boundary class. The boundary class used to model interaction between the system's surroundings and its inner workings. The boundary class interaction is involves transforming, translating events and noting changes in the system presentation. This class also model the parts of the system that depend on its surroundings. There are also class’s uses to model the parts that are independent of the system's surroundings such as entity classes and control classes. With that, the changing of communication protocol (GUI) mean changing only the boundary classes, not the entity and control classes. The boundary class also use to clarify the system's boundaries. With that, this class make it easier to understand the system. This class also providing a good point of departure for identifying related services for aid d...
Is context one of key elements for generating significant Architecture? It is said that Architecture, to be successful, has to be influential and relevant. Architecture does not exist in isolation but as a part of the environment. Architecture can be influenced by different factors, context being one of it. Context acts as an external elements influencing an object.

In recent years a cognizance has grown of the importance of software architecture. ”The software architecture of a system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships among them”-- Bass et al [1]. Software architectures are essential because they represent the single concept for understanding the structure of a system and form the basis for a collective understanding of a system and all its benefactors. The IEEE recommendation outlines architecture as the fundamental organization of a system embodied in its modules, their relationships to each other and to the environment and the main beliefs guiding its design and evolution.
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
Von Neumann architecture, or the Von Neumann model, stems from a 1945 computer architecture description by the physicist, mathematician, and polymath John von Neumann and others. This describes a design architecture for an electronic digital computer with a control unit containing an instruction register and program counter , external mass storage, subdivisions of a processing unit consisting of arithmetic logic unit and processor registers, a memory to store both data and commands, also an input and output mechanisms. The meaning of the term has grown to mean a stored-program computer in which a command fetch and a data operation cannot occur at the same time because they share a common bus. This is commonly referred to as the Von Neumann bottleneck and often limits the performance of a system.
Computers are very complex and have many different uses. This makes for a very complex system of parts that work together to do what the user wants from the computer. The purpose of this paper is to explain a few main components of the computer. The components covered are going to be system units, Motherboards, Central Processing Units, and Memory. Many people are not familiar with these terms and their meaning. These components are commonly mistaken for one and other.

An effective e-business architecture should be built after a careful analysis of the way a company does business, for implementing an appropriate architecture is a way to make businesses overall more efficient. When developing an e-business architecture, a company must first take into consideration its current business structure or how they would like this structure to be if it's a new business, and from that point develop an architecture that will take the business to a next level of organization and management.
META Group considers enterprise architecture as a process as opposed to an object, thereby referring to it as enterprise architecture process. Its enterprise architecture describes the systematic linkages between the enterprise business, technical architectures, information and enterprise solution architecture. It has modified the traditional enterprise architecture in a manner that extends from the level of business strate...
