The aim of this paper is verification of possibilities of Laravel PHP framework. An overview of literature is presented, which shows Laravel as a research tool in various scientific fields and compares it with other PHP language tools. The project of a test application was presented, which is a database of music albums with three datasets - one, two and five thousand albums. Laravel's Zend Framework and Symfony performance survey was based on, among other things, database loading time, database searches, and the time to generate a single album view with relationships. Summary of the information contained in the paper states that Laravel is an easy-to-use tool, with a number of app creation aids, but with performance outweighed by the frameworks compared to it, the most efficient of which is Zend Framework.

This article deals with the comparison of two technologies for manipulating 3D objects in terms of ease of use, ergonomics and intuitiveness. The comparison was based on the results obtained from the outcome of test tasks and questionnaires performed on the group of 15 people. Detailed research and test scenarios and additional questionnaires have been made. Each of the respondents had the opportunity to familiarize themselves with the device by performing three tests in two test scenarios (one per device).

This article compares two open source platforms supports e-commerce, such as: Wordpress with Woocommerce plugin and Magento Community Edition. The paper shows pros and cons of both systems. The main functionalities of them were tested and showed. Based on research - conducted measuring the speed of web page load by using online tools such as Google PageSpeed Insights and system popularity analysis based on social media and Internet forums, conclusion were made.

The article presents the use of .NET Core in web applications development. The analysis covers tests performed on a test application based on the .NET Core framework. The following benchmarking criteria were selected for the framework analysis: pattern search in text, counting parsing time, rendering operations on graphical files, adding files to archives, CRUD operation speed. These criteria were compared on two different operating systems - Windows, Linux. Additionally, the paper presents results obtained after the tests and their analysis. The hypothesis that tests will be executed faster on Windows than on Linux has only been partially confirmed.

This article presents the results of comparing code developing speeds and project loads across different frameworks to explore which of them seems to be the best choice in the long time. The analysis was carried out in terms of the exploratory study, the design of the sample project and the literature review. Comparison will make it possible to point to a better performance framework and prolong its use.

Work with database is one of base things in developing an application. Every technology/language uses own ways to work with database. In the case of Android the SQLite relational database management system is used. Analysis applies the read, write and delete of items from the table. SQLite is like a minimized version of desktop database management system so for every experiment very limited elements count is used.

The goal of this article was to perform analysis of usability possibilities of frontend framework AngularJS compared to native programming language JavaScript, on which it is based on. Several framework funcionalities were chosen and set together with self implemented solutions in JavaScript. Comparison was made according to specified criteria: usage simplicity, possibilities of utilization and reusability. Created scripts confirm accepted assumptions, that in JavaScript it is possible to write simplified and reusable implementations of useful mechanisms, which are present in AngularJS.

The aim of the article is to compare three programs for the optical text recognition. The problem of the optical text recognition has been defined. Next, briefly the functionality of this technology was described. The most important programs realizing the discussed problem were also characterized. The selected programs were tested using two samples of machine writing in Polish. The speed of the text recognition process was determined. The correctness of characters and words recognition in the analyzed text was also specified.

The paper contains comparison between Angular and BackboneJS frameworks. For research purposes, two single page applications were created. Both providing the same functionalities. In this article such elements were examined and compared: time of loading elements, number lines of code, size of compiled application. community gathered around frameworks and time needed to create the application using frameworks. The obtained results did not indicate a solution that was clearly better to be used in single page applications.

Artificial neural networks are one of the tools of modern text recognising systems from images, including handwritten ones. The article presents the results of a computational experiment aimed at analyzing the quality of recognition of handwritten digits by two artificial neural networks (ANNs) with different architecture and parameters. The correctness indicator was used as the basic criterion for the quality of character recognition. In addition, the number of neurons and their layers and the ANNs learning time were analyzed. The Python language and the TensorFlow library were used to create the ANNs, and software for their learning and testing. Both ANNs were learned and tested using the same big sets of images of handwritten characters.
