Using Spring Framework to develop web applications

Spring Framework is a popular platform for creating web applications. It consists of a container, an element management platform, and a set of integrated services for web user interfaces, transactions, and state retention. Spring has a modular structure. This allows you to use only those modules that are needed for a specific application and write clean and accessible code. The purpose of the work is to find and develop the most acceptable conditions for creating a forum of programmers. Users will be able to view profiles of other users, top-ics, answer questions or create their own. The web application was created using the Java programming language in the In-telliJ IDEA 2022 development environment. The Spring Boot framework technology stack was used; Spring Data JPA; jQuery library; Bootstrap framework; database Post-greSQL 12 and pgAdmin4. The project uses the MVC (model-view-controller) design pattern. According to the architectural feature of such a template, the system can be divided into three inter-connected parts, the first is a data model, the second is a view representing the user in-terface, and the third is a control module. To create a software product, a relational database was developed, which con-nects all subjects with connections. The software application consists of several web pages, the feature each of them is the implementation of certain functionality and restrictions on access rights.

COMPARATIVE ANALYSIS OF SOFTWARE DEVELOPMENT SYSTEMS BASED ON FRAMEWORKS

The article provides a comparative analysis of web frameworks based on the Python programming language. The right choice of a software development tool will allow developers to speed up the process of designing and software implementation of web resources. With the development of programming languages, solutions have begun to appear that make it easier for programmers to create web applications. In recent years, many tools of this type have been developed, including web frameworks. Some of them are used to develop small web applications, and other frameworks are used to create large-scale systems. The existing web frameworks differ from each other, but choosing them can be a difficult task for a programmer. Therefore, it is necessary to specify several parameters that are common to frameworks, according to which the desired web framework should be selected. The selected criteria make it possible to evaluate the frameworks more qualitatively and more objectively and speed up the process of design and software implementation of web resources. Due to the high demand for web applications, developers need to develop cost-effective, secure and well-coded web applications. Analyzing the Django framework, it can be argued that it is the most popular for web development, written in the Python programming language and using the MVC architecture. It is ideal for application projects with limited time and a small budget. If the application is not very voluminous and only simple URL routing and templates with a simple context are needed, then the Flask framework can be used instead of Django. The framework for building a Flask application in the resulting HTML files contains additional tags and scripts. The mechanism of work of processing forms also works differently. Flask stores more information about form fields on pages. The size of HTML files created using the Flask framework turns out to be significantly larger.

ANALYSIS OF THE USABILITY AND ACCESSIBILITY OF WEBSITES IN VIEW OF THEIR UNIVERSAL DESIGN PRINCIPLES

Universal design is a strategic approach for planning and designing both the products and their environment, aimed at making a given product available to the widest number of possible users. It ensures equality for all of them and the opportunity to participate in the society. This concept is also crucial in the process of designing and developing software. The research was conducted with the use of four services, three of them were implemented for the purpose of this study. Two of them took into consideration the principles of universal design, while the others did not. The aim of the study was verification of the level of usability and accessibility of services by means of three independent methods: the LUT (Lublin University of Technology) checklist, an assessment taking into account WCAG 2.0 (Web Content Accessibility Guidelines) standards using the automatic WAVE evaluation tool (Web Accessibility Evaluation Tool) and a device allowing to track the movement of the eye while performing various tasks on websites. The websites were assessed by twenty experts in the field of creating web application interfaces, using the LUT checklist. The time to the first fixation (TTFF) that it took respondents to look at specific website elements was measured using the eye tracker device and iMotions software. All websites were checked by means of the WAVE tool to detect irregularities and non-compliance with universal design standards. The analysis performed clearly indicated that websites that follow the universal design guidelines were more useful, intuitive and accessible for users. It might be concluded that interfaces allow to find necessary information and perform desired actions in a shorter time when prepared in accordance with the principles of universal design.

Customer Prioritization Integrated Supply Chain Optimization Model with Outsourcing Strategies.

Pre-COVID-19, most of the supply chains functioned with more capacity than demand. However, COVID-19 changed traditional supply chains' dynamics, resulting in more demand than their production capacity. This article presents a multiobjective and multiperiod supply chain network design along with customer prioritization, keeping in view price discounts and outsourcing strategies to deal with the situation when demand exceeds the production capacity. Initially, a multiperiod, multiobjective supply chain network is designed that incorporates prices discounts, customer prioritization, and outsourcing strategies. The main objectives are profit and prioritization maximization and time minimization. The introduction of the prioritization objective function having customer ranking as a parameter and considering less capacity than demand and outsourcing differentiates this model from the literature. A four-valued neutrosophic multiobjective optimization method is introduced to solve the model developed. To validate the model, a case study of the supply chain of a surgical mask is presented as the real-life application of research. The research findings are useful for the managers to make price discounts and preferred customer prioritization decisions under uncertainty and imbalance between supply and demand. In future, the logic in the proposed model can be used to create web application for optimal decision-making in supply chains.
