Development of web applications consists of many processes. One of them is choosing appropriate database management system which may have huge impact on application performance. Large availability of database management systems makes it not an easy choice. The goal of this paper is to compare efficiency of databases in Django-based applications and three different database management systems: MySQL, PostgreSQL and MongoDB.
The article analyses the possibilities of creating web applications using two competing solutions based on Java (Spring) and PHP (Laravel) languages. The elements of implementation, security aspects and the efficiency of created test applications were compared. The aim of
the research was to identify a platform offering greater opportunities, easier to learn and more programmer-friendly, and also a more efficient indication. Analysing the solutions used in both technologies - an attempt was made to assess their competitiveness with each other.
The paper presents an analysis of the Cucumber automated test tool and describes how this tool is used in practice.As part of the paper, several test cases were created to fully verify the operation of the chosen approach to testing in programming in Java and Kotlin languages also the time of testing were compared in both languages from the object-oriented language family.
The article describes implementation of internet applications supporting business management, basing on implementations in
particular travel agencies. Various web application types of were presented, with the analysis of pros and cons of their usage. Diagnostic survey method was used in the analysis. Results of research have shown, that most popular web application used by travel agencies is CRM.
Companies from travel business line proved efficiency of this tool, by increase of sales performance.
The subject of this article is to compare iOS mobile operation system encryption algorithms performance. The main target is to analyze symmetrical and asymmetrical algorithms, test them how much time encryptionand key generation operations take. Tests were carried out on various devices with the same version of operating system.
Article shows a way of use an electronic heart rate monitor and surround sound to interact with user in virtual reality. The method of
interact was presented on the basis of four scenarios. In the first two scenarios the behawior of objects in virtual reality depended on the indications of heart rate monitor in the next two scenarios heart rate monitor was just a measurer. The article attempts to find an answer to the question whether virtual reality affects the pulse of the examined person and whether surround sound affects the pulse of the examined person, and if so which factor influences the pulse to a greater extent. The individual resting pulse was measured and then was determined the pulse variability for each scenario. In the research, an analysis was carried for each person individually and collective analysis for each scenario. In addition, inference was also based on questionnaires before and after research.
The article presents the author's method of studying human reaction to spatial sound. Public devices such as: Kinect sensor, Creative surround sound set were used. A research method, method of analysis and necessary research scenarios were developed. In addition, two questionnaires were proposed: before and after the study. Next, the results of the research were developed and the conclusions were formulated on their basis.
The main purpose of the article is an analysis of differences between frameworks of native applications and cross-platform. The emphasis was put on presenting technologies that are currently used, their development and the situation on the market. The work includes a discussion of selected technologies used in mobile programming with division into native and high level languages. The differences between the processes of manufacturing mobile applications were presented.
The paper presents the results of comparison of the possibilities of creating web applications in PHP technology on the example of
popular programming platforms Yii2 and Laravel. The research was carried out by implementing two applications with the same functionality using the same database. In both technologies, the application structure, elements of creating the graphical interface, selected code metrics and efficiency of working with databases were compared. The summary indicates the most important advantages and disadvantages of both solutions.
The article presents one of the problems encountered when using the C ++ 14 standard along with the Google Mock library. Based on the introduced problem, possible solutions were discussed, as well as an improved scheme for the TDD approach was presented.
The aim of this work was to compare the performance of selected programming languages (Python, C) by measuring the time of operation and use of computer resources of the genetic algorithm for given parameters, and then assessing whether the scripting language can be
comparable in terms of speed with the compiled language. For this purpose, a genetic algorithm has been implemented in each of these languages and test scenarios were developed. The results form the basis for the final evaluation of the performance of the presented languages and proof that the scripting language can achieve operating times comparable to the compiled language.
The article presents the results of comparison of tools for creating SPA applications using the Ember and React framework. The research was carried out using test applications with the same functionality but implemented on both platforms. The comparison concerned the structure of the project, selected code metrics and the effectiveness of page rendering.
The following article presents a comparison of multithread and multiprocess communication and synchronization. The theoretical comparison was supported by the solutions of practical, classical synchronization problems. The availability of communication and synchronization mechanisms in the Boost library and in IPC interprocess communication was compared.A subjective assessment of the difficulty in implementation and applications performance was also presented.
The article presents the results of a review of libraries for the Android platform, supporting the integration with REST and SOAP network services. An analysis of the performance and complexity of client programs using the most popular solutions. The research methods were based on the author's mobile application that enable the simulation of asynchronous communication. The result of the research is a comparative analysis of libraries, that facilitate the selection of adequate solutions.
The article presents the results after conducting surveys in selected enterprises of Ukraine and Poland, as well as described the comparison of information security policies in enterprises and verbal, which enterprises better protect information, taking into account the companies of both countries as a research subject.Thе рrоfеssiоnаl litеrаturе оf thе givеn issuе, аs wеll аs Intеrnеt sоurсеs, wеrе usеd.
