Software architecture represents a common abstraction of a system that most if not all of the system 's stakeholders can use as a basis for mutual understanding, negotiation, consensus, and communication [2,12]. According to Microsoft’s definition “software architecture is the process of defining a structured solution that meets all of the technical and operational requirements, while optimizing common quality attributes such as performance, security, and manageability. It involves a series of decisions based on a wide range of factors, and each of these decisions can have considerable impact on the quality, performance, maintainability, and overall success of the application [11]. Software architecture manifests the earliest design decisions about a system, and these early bindings carry weight far out of proportion to their individual gravity with respect to the system 's remaining development, its deployment, and its maintenance life and is also the earliest point at which design decisions governing the system to be built can be analyzed. Software architecture should be transferable to other system which exhibits the quality attribute and functional requirements and can promote large-scale re-use [12].
Rik Farenhorst and Remco C. de Boer have proposed four primary views on architectural knowledge [3]. In pattern centric view, Patterns serve two purposes, patterns are reusable solutions that can be applied to recurring problems and they also form a vocabulary that provides a common frame of reference, which eases sharing architectural knowledge between developers. Requirements are the roots of a software architecture, so in requirement-centric view of architecture, requirements and the architecture need be co-developed and all ...

...ons that are important for traceability to support software evolution, i.e. Process automation for generating and recovering traceability information, procedure simplicity for a whole tracing process and best results achievement in term of highest accuracy, completeness, and up-to-date traceability information. To address these directions they came-up with Multifaceted Requirement Traceability Approach (MRTA) to support software evolution. Thus, traceability provides assistance in understanding the relationships between requirements and design. Make architectural knowledge more explicit and it would be difficult to maintain implicit relationships between the architectural objects in absence of traceable architectural artefacts. Tractability helps in maintaining one consistent view of all requirements between all stakeholders.

Software Testing Essay

- Software Testing Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming process that requires technical sophistication and proper planning” (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of s...   [tags: Technology Computers Papers]
