Comparison of Technologies for Object-Relational Mapping
Fatrdla, Pavel ; Burget, Radek (referee) ; Zendulka, Jaroslav (advisor)
Diploma thesis deals with the contemporary object-relational mapping (ORM) technologies for Java. It briefly describes also competing technologies for persisting objects in files, object and object-relational databases. However main part of the thesis is the persistence of objects in relational databases using ORM frameworks. The work begins with studying general methods and issues, that these frameworks have to solve. Next, it chooses and deeply describes some ORM frameworks. They are later demonstrated on the demo application. In the following part there is a description of the problems I have been facing during the implementation of the persistence using these frameworks. Finally, there is an evaluation and a comparison of these frameworks.

Information System for Project Management and Collaboration Support
Vítek, Tomáš ; Květoňová, Šárka (referee) ; Rychlý, Marek (advisor)
Project management is used in increasing number of companies. Competition on the market requires companies to work more efficiently and approach separate orders as independent projects. Teams that work on the projects consist of employees from different departments, from subcontractors and from the client as well. Rapid development of broadband internet connection changed work methods and use of information technology. Thanks to ubiquitous internet connection software application delivery model known as Software as a Service (SaaS) is gaining on popularity. Main aim of this project is to design an information system that would support project management and allow effective team communication and collaboration.

E-Shop
Šibřina, Ondřej ; Rogalewicz, Adam (referee) ; Dittrich, Petr (advisor)
This bachalor's thesis discusses design and implementation of internet-based sales system that allows ordering goods (such as traditional e-commerce) and keep all the work connected with the processing of orders. This system also implements features that help owner with leading this e-commerce (keeping stock records, billing, shipping). It deals with the design and implementation of SEO-friendly application, which is also fully localized. This thesis also deals with modern elements of web applications, which are base of this system (frameworks, database mappers, etc.)

Information System Database Layer with an Application Interface
Špaček, Jakub ; Milička, Martin (referee) ; Burget, Radek (advisor)
This thesis is a part of a student project called Yumified. It is a mobile application that allows users to rate melas in catering facilities. The users can also browse all the ratings. The thesis describes the design and implementation of an application interface and a database that serve to collect, store and provide the related information. For this purpose, we use the REST application interface, Symfony PHP framework and the Doctrine library for high-level database access.

Optimization of KPI Processing
Šulc, Ondřej ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
This thesis deals with the optimization of data processing from IoT sensors of smart cities into the form of key performance indicators (abbr. KPI). KPIs are a mean of monitoring a large amount of data and expressing the status of performance factors affecting the prosperity of the entire city. Data processing in this form is a computationally demanding process, but it consists of a large number of mutually independent calculations. Therefore the goal of this thesis was to perform optimization using parallelization. In parallel processing, calculations can be divided between multiple threads, enabling all available computing resources (CPU cores) to be fully used. This concept was practically implemented in the Smart City project of Logimic company. However, the project is built on the Node.js platform, and when using parallelization there are complications with the use of libraries for object-relational mapping (abbr. ORM). ORM libraries on the Node.js platform are not always ready to work in a parallel environment. This problem is solved by creating a separate instance of the used library for each parallel thread. The thesis focuses on reducing the overhead associated with this and also on the correct distribution of work between parallel threads so that all cores are used equally. The results of this work prove that optimizing IoT data processing using parallelization leads to a significant speedup that conforms to Amdahl's law, as overhead problems can be reduced to a negligible minimum.

Conference System for Excel@FIT
Kobelka, Martin ; Szőke, Igor (referee) ; Veigend, Petr (advisor)
The main goal of this thesis is to initially conduct a detailed analysis of the issues related to organizing scientific conferences while focusing on the workflow of the Excel@FIT conference and subsequently mapping the workflow of several other conferences organized in the field of information technology in the theoretical part. Then, in the practical part, the task is to design an information system specifically for the Excel@FIT conference and implement it in the form of a web application. The resulting web application for conference administration is developed using the programming languages PHP and TypeScript. The client side is designed as a single-page web application that communicates with the server side through REST API. The application ensures efficient and smooth conference management, registering and reviewing papers and generating exports for evaluation committees. The output is a fully functional application that has been tested on data from previous years and can be easily extended with new functionalities if needed.
