A model-driven framework for data-driven applications in serverless cloud computing.

In a serverless cloud computing environment, the cloud provider dynamically manages the allocation of resources whereas the developers purely focus on their applications. The data-driven applications in serverless cloud computing mainly address the web as well as other distributed scenarios, and therefore, it is essential to offer a consistent user experience across different connection types. In order to address the issues of data-driven application in a real-time distributed environment, the use of GraphQL (Graph Query Language) is getting more and more popularity in state-of-the-art cloud computing approaches. However, the existing solutions target the low level implementation of GraphQL, for the development of a complex data-driven application, which may lead to several errors and involve a significant amount of development efforts due to various users’ requirements in real-time. Therefore, it is critical to simplify the development process of data-driven applications in a serverless cloud computing environment. Consequently, this research introduces UMLPDA (Unified Modeling Language Profile for Data-driven Applications), which adopts the concepts of UML-based Model-driven Architectures to model the frontend as well as the backend requirements for data-driven applications developed at a higher abstraction level. Particularly, a modeling approach is proposed to resolve the development complexities such as data communication and synchronization. Subsequently, a complete open source transformation engine is developed using a Model-to-Text approach to automatically generate the frontend as well as backend low level implementations of Angular2 and GraphQL respectively. The validation of proposed work is performed with three different case studies, deployed on Amazon Web Services platform. The results show that the proposed framework enables to develop the data-driven applications with simplicity.

Competition in sports field leasing is quite fast these days, making sports field managers improve facilities and provide competitive prices to attract sports field tenants. However, this progress was not accompanied by advances in technology so that sports field managers still had to do the manual method for field operations and promotion. On the side of the tenants of the sports field also still have to go to the sports field to find out the availability of schedules, facilities, and prices offered. Then many tenants who have an interest in exercising more than one branch of sport, therefore researchers use the concept of a marketplace that can bring together the managers of sports fields with field tenants in one container. In the application development process, it is done by using the agile method application development method because in its development it can be possible to collaborate and correct each other among team members to increase the customer satisfaction ratio. The application implementation uses the Laravel framework, PHP for programming language, and the MySQL for Database Management System. The results of the study can be concluded that the use of the marketplace concept can bring together prospective field tenants with many field managers and the ease of finding a sports field following the wishes of tenants by selecting the category of field, price and closest location and the manager of the sports field can promote the sports field by registering the field.

Developing Framework for Web Based e-Commerce: Secure-SDLC

Software development usually follows the stages known as the Software Development Life Cycle (SDLC). Development begins with the requirements phase and then continues with the design, development of test plans, implementation (coding), testing, and deployment. However, the security aspect has not been explicitly reflected in SDLC. In fact security must be present at every stage of the SDLC. Application of security in the process of developing software, especially e-Commerce, one of which uses the Security Development Lifecycle-Agile (SDL-Agile) method.

Approaching Software Engineering for Marine Sciences: A Single Development Process for Multiple End-User Applications

Research software is currently used by a large number of scientists on a daily basis, and everything indicates that this trend will continue to increase in the future. Most of this scientific software is very often developed by the researchers themselves, who usually make it available to the rest of the scientific community. Although the relationship between science and software is unquestionably useful, it is not always successful. Some of the critical problems that scientists face include a lack of training in software development, a shortage of time and resources, or difficulty in effectively cooperating with other colleagues. Additional challenges arise in the context of increasingly common cross-cutting and multidisciplinary research. This often results in the developed software and code being slow, not reusable, lacks visibility and dissemination, and in the worst cases it is defective and unreliable. Therefore, a multidisciplinary framework is needed to meet the demands of both scientists and software engineers and handle the situation successfully. However, a multidisciplinary team is not always sufficient to solve this problem, and it is necessary to have links between scientists and developers: software engineers with a solid scientific background. This paper presents the approach used in the framework of the PROTOCOL project, and more particularly in the development of its applied software, in which a tool for the characterization of climate agents has been developed. The main guidelines of the development process include, among others, modularity, distributed control version, unit testing, profiling, inline documentation and the use of best practices and tools.

A template-based code generator for web applications

The importance and usage of web applications grow every day. Today from small businesses to large-scale corporations, many institutions prefer web applications for both their internal and external services. Code size and complexity of these kinds of applications grow rapidly. This brings up the question of how to improve the development process of web applications. A solution can be to use code generators. This paper introduces a template-based code generator to improve the development process of web applications. The code generator was developed and integrated into a real-life web application. Today, the web application together with the code generator is actively used in industry. This proves that an effective integration of a template-based code generator into a real-life large-scale web application can be achieved. In addition, the effectiveness of automatic code generation to manual implementation was shown with experimentation. Throughout the experiments, bug-free code generation was observed. Also, 98.95% improvement in average development time, 93.97% improvement in average test run count, and 49.37% improvement in average code size was achieved.

Model of Tools for Requirements Elicitation Process for Children’s Learning Applications

Requirements Elicitation are the initial stages in the application development process, where a set of needs from the system will be built and obtained by communicating with stakeholders who have a direct and indirect influence on those needs. Failure in the requirements elicitation process was caused by weak communication. Communication is an essential thing in carrying out the requirements elicitation process. The selection of the right elicitation technique is not only a solution. Informants as sources of information on requirements also need to be considered. The choice of the correct technique often fails because of the tools not useful. The availability of the right form of equipment needs to be considered so that the communication between the elicitation team and the informant goes well. Children have characteristics not the same as adults. Limitations in terms of psychomotor, cognitive, and emotional children are considered in choosing elicitation techniques and tools. These limitations are also influenced by the age range of child development. The use of digital elicitation devices is recommended to be used in the requirements elicitation process. The presentation of interactive tools makes it easier for children to convey their desires. In learning applications for children, aspects of pedagogy that need to be explored are learning styles and children's thinking abilities. Every child in every age range has a different preference for learning style. That is because children do not have learning experiences. That also applies to the level of thinking ability of children. Therefore, these two things need to be appropriately explored when the learning application development process. The proposed elicitation tool model was made by taking into account both components of that pedagogical aspects. The test results of the built model show that the application has satisfaction. That means that children can communicate well in conveying the needed as requirements to the learning application.

An Agile-Based Integrated Framework for Mobile Application Development Considering Ilities

The development of mobile apps during the last decade has had a significant increase in its share of the software market. While there are specific characteristics that separate it from traditional software development, there is a lack of guidance on issues encountered during the mobile software development process. With the aim of defining a mobile application development framework that considers the specific characteristics of developing mobile apps, we started by carrying out a systematic mapping study of the software development process for mobile applications, then we administered a survey and completed a qualitative study with industry experts. These studies allowed us to identify the main trends in the software process for mobile apps, and to uncover the main challenges for app development. We have organized the findings in a framework that integrates the specific challenges of mobile development, which we call Mobile Ilities, with software development activities that are linked through an agile process. The results of early tests carried out with computer science students are encouraging. Our proposal has served as a guide for novice developers throughout the process of creating a final product, combining the existing knowledge of developers about Scrum with the specific characteristics of mobile development, and providing mechanisms to link these characteristics with the elements of the development process.

Modeling and Assessing the Power Consumption Behavior of Sensor Nodes using Petri Nets

Power Consumption is an influential and important concern in Wireless Sensor Networks (WSNs). Assessing and determining the impact of the power behavior of sensor nodes is an inclusive concern that should be executed at the network pre-deployment phase rather than post-deployment phase. Providing an accurate power modeling improves the development process of WSN applications and protocols. This paper introduces the use of Colored Petri Nets (CPNs) to model the power behavior and relations among different sensor node components when operated in an event driven environment. The objective is to figure out the overall power behavior of the nodes by considering power consumed accompanied with different states transition at a specific packets arrival and service rate values. Colored Petri Nets is a modeling language employed for validating and evaluating concurrent and distributed systems. The introduced model is beneficial since it provides the network designer with a way to determine surrogate designs or to check the compatibility of an existing power model behavior. The proposed model has been validated through the comparison of the power behaviors of two sensor nodes Mica2 and Telos. The results demonstrate the efficiency of using the proposed model to draw and analyze the WSNs energy consumption behavior.

A Knowledge-Based Integrated System of Hesitant Fuzzy Set, AHP and TOPSIS for Evaluating Security-Durability of Web Applications

There has been a phenomenal increase in the use of web applications in every facet of human endeavor. From education, healthcare, banking, business to governance and so much more now depends on secure web applications. This accelerated growth in the use of web applications has led to increase in the complexity of security and hence the present day developers have to contribute more significantly towards meeting the users' requirements. However, the high security of web application is not yet efficacious enough because the durability of web application is not as much as it should be. In this context, it is important to consider that ensuring sustainability of security at the early stage of web application development process may reduce costs and rework entailed during the development of secure and durable web applications. Hence, there is a need to focus on increasing the life-span of a secure web application. Quantitative estimation of security-durability plays a significant role for improving the life-span of a secure web application. Thus, to optimize the security assurance effort for a specific life-span, this paper is aimed at estimating the security-durability of web application. For estimating security-durability, this paper uses a hybrid approach of Hesitant Fuzzy (HF) sets, Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) techniques. The effectiveness of the combined approach of HF-AHP-TOPSIS is tested for its accuracy in a web application for an academic institution, Babasaheb Bhimrao Ambedkar University in India. To check the sensitivity of outcomes, authors of the paper have taken altered forms of the University's web application. The result established contains the security-durability assessment. This work seeks to be an important contribution in enhancing the security-durability and would be beneficial for experts who are working in this domain.

Semantic Node-RED for rapid development of interoperable industrial IoT applications

The evolution of IoT has revolutionized industrial automation. Industrial devices at every level such as field devices, control devices, enterprise level devices etc., are connected to the Internet, where they can be accessed easily. It has significantly changed the way applications are developed on the industrial automation systems. It led to the paradigm shift where novel IoT application development tools such as Node-RED can be used to develop complex industrial applications as IoT orchestrations. However, in the current state, these applications are bound strictly to devices from specific vendors and ecosystems. They cannot be re-used with devices from other vendors and platforms, since the applications are not semantically interoperable. For this purpose, it is desirable to use platform-independent, vendor-neutral application templates for common automation tasks. However, in the current state in Node-RED such reusable and interoperable application templates cannot be developed. The interoperability problem at the data level can be addressed in IoT, using Semantic Web (SW) technologies. However, for an industrial engineer or an IoT application developer, SW technologies are not very easy to use. In order to enable efficient use of SW technologies to create interoperable IoT applications, novel IoT tools are required. For this purpose, in this paper we propose a novel semantic extension to the widely used Node-RED tool by introducing semantic definitions such as iot.schema.org semantic models into Node-RED. The tool guides a non-expert in semantic technologies such as a device vendor, a machine builder to configure the semantics of a device consistently. Moreover, it also enables an engineer, IoT application developer to design and develop semantically interoperable IoT applications with minimal effort. Our approach accelerates the application development process by introducing novel semantic application templates called Recipes in Node-RED. Using Recipes, complex application development tasks such as skill matching between Recipes and existing things can be automated. We will present the approach to perform automated skill matching on the Cloud or on the Edge of an automation system. We performed quantitative and qualitative evaluation of our approach to test the feasibility and scalability of the approach in real world scenarios. The results of the evaluation are presented and discussed in the paper.

Generating educational mobile applications using UIDPs identified by artificial intelligence techniques

Commercial mobile devices vary in brand, size, and functionalities, but they all allow people to interact with educational applications. In software engineering, application development techniques, approaches, methodologies, and processes (e.g., BBD, FDD, RAD, DDD) are often time consuming, costly, or aim at expert developers – which implies that users outside the software development field (e.g., teachers) need great practice to become experienced application developers. This work proposes an artificial-intelligence-based process for generating educational mobile apps from freehand-generated images. The images’ design is based on User Interface Design Pattern (UIDP) representations. As a proof of concept, we introduce EduMatic, an application development tool. To test our process, we assessed Wiki-Comp, an application built with EduMatic, along with three other external educational applications: Khan Academy, Wiki encyclopedia, and Kiwix. According to the evaluation results, Wiki-Comp outstands in functionality, usability, and performance aspects.
