Ženčák, Tomáš ; Kučera, Jan (referee) ; Matoušek, Jiří (advisor)
The goal of this work is to create a prefix set generator which will be capable of generating a prefix set from parameters specified in the ClassBench toolset. This work describes a possible approach to generation, as well as the final algorithm for prefix set generation. The resulting generator is able to generate prefix sets whose average deviation from the target parameters is typically orders of magnitude lower than the deviation of sets generated by ClassBench.

Testing in agile projects
Košťál, Ondřej ; Buchalcevová, Alena (advisor) ; Kučera, Jan (referee)
This thesis deals with the description of software testing in agile projects. Unlike the traditionally managed projects, testing in agile projects is not a discrete phase. In agile managed projects, testing is integrated into the entire development process. Testing takes place continuously throughout the project to ensure frequent delivery of valuable software in short development cycles. The aim of this diploma thesis is to create a comprehensive description of software testing in agile projects. The introductory part describes in detail the principles and values of the Agile Manifesto, as it is the cornerstone of the whole agile concept. Next, the basic differences between the traditional and agile approach to software development, aspects of agile design testing and agile methodology are described. The following section looks into the matter of the agile team, that includes its size, structure, and approaches that an agile team uses during its work. In terms of testing, this is in particular the Whole-Team Approach. The thesis then describes the role of the agile tester, his/her knowledge, skills and activities, which contribute to the creation of valuable software. As next, the key agile artifacts, meetings, and practices related to testing are described. The final part of this thesis presents the principles and practices of agile testing. Another aim is to design a teaching concept for 4IT479 - Software Testing in Agile Projects. The teaching concept is designed based on the theoretical knowledge described in this thesis. The teaching concept is further complemented by simulations that help students better acquire the theoretical knowledge.

The thesis addresses the information system improvement for the specific sporting organization. The main motivation behind this and assumption, too, is the intention to improve operation in the sporting organization TAEHAN. The main aim of the thesis is the improvement proposal for the current IS. It is achieved by fulfilling the following objectives - current situation analysis and creation of proposals for improvement measures, new IS detailed requirements specification and its rough design which should express its main structural features. This set of objectives corresponds to the way of organizing thesis into individual chapters. In order to meet the first objective, it was necessary to create a list of improvement measures, which results from the description of the current situation and identification of the existing solution shortcomings. In terms of the benefit it is the most important part. The second objective was achieved by drawing up a comprehensive list of validated requirements. As a validation method, it was chosen the check based on checklist taken from existing information sources. The last objective was the design of new IS form. It was divided into two parts - in the first, based on the use cases, the IS was divided into several subsystems and in the second part, rough architecture of the possible solution was described including the advantages of its certain aspects.

This thesis deals with the possibilities of using open linked data in healthcare. The first part of thesis deals with the problematics of open linked data and defines major terms, legislative view and presents main benefits and risks from open data on research based on case studies and analysis. The second part of thesis deals with analysis of datasets in Czech Republic and abroad, focusing specially on datasets from healthcare. This objective is achieved by comparing and analyzing national open data catalogues in terms of categorization of its content, usage by applications and openness in terms of used data formats. Following third part of thesis aims to create a model dataset according to National set of indicators of health services. Its structure and generated physical representation from extracted and generated data is based on research of available indicators of health services quality in the Czech Republic and Great Britain. The last part of this thesis aims to create a design of web application, using said dataset, and its subsequent verification by implementation. The outcome is web application mediating catalogue of medical facilities in the Czech Republic and mechanism for comparing health care facilities by index of mortality.

Comparison of selected database systems
Fiala, Adam ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
This bachelor thesis is based on comparison of popular open source and proprietary database systems. The criteria were preselected in advance and highlight the strengths and weaknesses of each defined system. In addition to that, this thesis is focused on the characteristics which are playing an important role and might be significant for database selection. First part of the work is dedicated to database problematic concepts and various software categories where each individual system belongs along with the associated types of licenses. This thesis is also providing an overview of market analysis that is followed by introduction of selected products. Second part of the work is mainly focused on criteria selection and actual comparison. As a conclusion, an overview summary of results are gathered which can serve as an important information for selecting the right database management system.

Comparison of database systems from the point of view of database administration
Andreyuk, Yauheniya ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
This thesis focuses on relational database systems. The main goal of this thesis is to compare two selected database systems - one commercial and one Open Source, which will be compared using criteria, focused on the database administration. The first part provides a theoretical basis concerning the database systems (it will also include a description of the relational principle) and types of licenses under which the software may be issued. The main objective of this section is to create a sufficient theoretical basis for understanding the rest of the paper. The next section explains term database administration and shows the difference between the terms data management and database management. Next follows the analysis of the tasks performed by the database administrator and a description of each task. This part is fundamental for the rest of the thesis, because it will be used as a basis for a comparison. In the next section one Open Source and one commercial relational database system will be chosen. In the part I will also briefly describe the history of each system and their architecture. At the end the two systems are compared. The main asset of this thesis I see in analysis of database administrator tasks and comparison of how different systems help simplify these tasks.
