Improving the quality of web applications with web specific goal driven requirements engineering

Abstract

Requirements Analysis is the most important phase in Software development. It is a known fact now that if this phase is carried out properly the cost and effort of the project can be greatly reduced. Web applications are very important in today's times. Effectively, every organization and even individual has a web application to represent itself. The Web applications have grown from just information providers to full-fledged legacy systems with complex processes. There are various methods of web application development, but hardly any method focuses on detailed requirements analysis that is required owing to the criticality of web applications. Goal oriented requirements engineering techniques have proven to be very effective in requirements analysis. Application of goal driven methodologies for web specific requirements can improve the quality of web applications besides saving cost and effort required in the project. The special characteristics of GORE techniques like analysis of softgoals and interdependencies between various requirements help in elimination of conflicts at early stages of web application development. GORE techniques also facilitate evaluation of goal models that helps in choosing amongst the design alternatives and checking completeness of the requirements model leading to Software Requirements Specification.The implementation of web specific goal driven framework is shown in the paper and validated through a usability survey.

Goal Oriented Requirements Engineering for Blockchain based Food Supply Chain

“…In presence of conflicting evidence for the satisfaction of a goal, the decision involves negotiation with the stakeholders. A popular goal and scenario based standard called, User Requirements Notation [9] has been adopted for many applications like web applications [10], Business processes [11] and is a potential proposed solution for early requirements analysis of blockchain systems in this paper.…”

Development of Web and Mobile Applications for Chemical Toxicity Prediction

“…51,52 All the functionalities are orchestrated by Flask (back-front-end), which is responsible to call the individual modules in the back-end and interact with the user in the front-end, using the responsive web-based templates in HTML5 and JavaScript (front-end). The features described here were used to develop the two innovative web apps, named Pred-hERG, to identify possible hERG blockers and non-blockers, and Pred-Skin, for assessment of skin sensitization potential of chemicals (see Pred-hERG and Pred-Skin sections).…”

“…Pred-Skin front-back-end technology (full-stack). 52 (1) front-end using the responsive web-based templates in HTML5 and JavaScript for the user to draw/paste the chemical; (2) RDKit ECFP-4 fingerprint (Morgan) representation is calculated on the back-end; (3) scikit-learn API machine learning model runs on the back-end; (4) the front-end responsive framework templates based on Flask is rendered with the models predictions and the probability maps. 51 computational methods for addressing toxicity potential of chemicals is of upmost importance.…”

Web based Approach to Overcome the Market Information Gap between Poultry Farmers and Potential Buyers in Tanzania

“…"Nowadays, web applications play a significant role in the success of the business, and have grown very fast in the current market" (Panthi and Mohapatra, 2017;Sharma and Sheth, 2004). The web has a significant impact on all aspects of our life since we look for all the answers on the internet (Chawla et al, 2017). Web applications spread wide because they are easy to use and maintain (Chawla et al, 2017).…”

“…The web has a significant impact on all aspects of our life since we look for all the answers on the internet (Chawla et al, 2017). Web applications spread wide because they are easy to use and maintain (Chawla et al, 2017). The significance of web applications has potential to address the challenge on provision of market information to poultry farmers in Tanzania.…”
