REQUIREMENTS ANALYSIS ALGEBRA:DESIGNING QUALITY SOFTWARE

For software systems to be of good quality and acceptable to users, it is pre-requisite that the software developed so far must conform to user’s needs at its best. Moreover, quality requirements are essential for a software system to be developed. The software must comply with users’ requirements either functional and/or non-functional. The process of gathering and analyzing essential and complete user requirements is challenging one. As development of cloud applications is concerned, the requirements gathering and analysis process seems to be more complex due to crucial nature of user requirements particularly encompassing additional security requirements. Key challenge in cloud computing is data security so securities concerns are supposed to be the most essential factor in the domain of cloud computing applications. Such challenge demands a formally secure System Development Life Cycle (SDLC). Our research study proposes requirement analysis algebra that may provide a formal basis to requirement engineering and consequently may help the analyst in analyzing both functional and security requirements of cloud applications to be developed. The application of algebra proposed may enhance understanding of system requirements phase and improve the security requirements significantly.
