Menzel, Aleš ; Palovská, Helena (advisor) ; Chudán, David (referee)
This thesis consists of analysing database requirements, designing and creating a database for the needs of a reservation system and its corresponding parts. The purpose of this thesis is the practical implementation of the database and subsequently creating an application in the form of an administration interface, which is implemented in MySQL database platform and web technologies. Objective of the application is to provide complex system, which connects the parametric administration system with web pages in such a way, that the administrator of the application can manage the application from within the administration section. Requirements for this application and database are based on analysing the competitor's products and my own experience with creating a web application for a small pension. The goal is achieved by designing a flawless database and implementing the application. Furthermore the application proves and validates the database implementation by using test data. Main contribution of the thesis is completed application based on a high quality database model that is ready for deployment in practice. Structure of the thesis consists of two parts. First part describes theoretical basics that are important to know before designing a database and a short introduction to history of database models. The second part is dedicated to designing the database itself.

Web collaboration tool
Hoch, Tomáš ; Sklenák, Vilém (advisor) ; Chudán, David (referee)
The main goal of this thesis is to develop a web application for teamwork support. The thesis deals not only with writing of source code but also with all usual phases of software development. The first phase starts with a general view of groupware-type application. Another part of this phase is research of available applications of this type and finally the requirements for developing such application are specified. The next phase suggests a solution which aims to formulate the most accurate specific requirements for the final application, using several models. The thesis then deals with realization of the suggested solution and eventually the application is created. The last phase is devoted to testing of the application and verification if the required result was achieved

The real task of data mining
Trondin, Anton ; Berka, Petr (advisor) ; Chudán, David (referee)
Diploma thesis " The real role of knowledge mining " is divided into two major parts, the theoretical and the practical. The practical part describes the basic concepts of data mining, various methods and types of tasks used for knowledge discovery in databases and algorithms used in this area . Main focus is devoted to the CRISP -DM methodology and to various stages of knowledge discovery from databases. This methodology will be later used as the basis for practical part of the thesis while other less known methods used for data mining won`t be neglected. List of paid and free software which can be used for knowledge mining in databases is presented at the end of theoretical part. The second part of the thesis is focused on the practical step by step application of the CRISP -DM methodology, which contains real data from the field of mobile communications. Data mining task used in practical part is the behavioral prediction of mobile carrier customers. Supporting the practical part of the thesis, IBM SPSS Modeler was used as a main software for knowledge mining. Key words: data mining, knowledge disvocery in databases. Churm management, prediction, CRISP-DM.

Combining OLAP and data mining for analysis on trainee dataset
Borokshinova, Anastasia ; Chudán, David (advisor) ; Šimůnek, Milan (referee)
The aim of this thesis is to show the possibility of combining two data analyses techniques OLAP and data mining in a certain area. The principal method of achieving the aim will be continuous comparison and check of acquired results using two techniques. A practise dataset on credits provided to physical persons is used for practical application. The data analysis will be performed using Power Pivot MS Excel complement and LISp-Miner system. For work with LISp-System the 4ft Miner procedure will specifically be used, which proceeds according to respected CRISP-DM data mining methodology. The thesis added value consists first of all in presentation of a possibility of OLAP and data mining linkage on the same dataset, thus reducing the number of erroneous conclusions which analysers might arrive at on the basis of one technique. Other benefits consist in presentation of relational data transfer to multi-dimensional structure and practical options of 4ft-Miner system LISp-Miner procedure usage.

Vybrané aplikace a služby webu 2.0
Chudán, David ; Toman, Prokop (advisor)
Předkládaná diplomová práce je rozdělena do dvou hlavních částí. První část je teoretická, která se zaměřuje na popis jednotlivých oblastí webu 2.0 a na popis vybraných aplikací a služeb. Druhá, praktická část se zaměřuje na srovnání vybraných aplikací webu 2.0, konkrétně na srovnání blogovacích systémů, online textových editorů a online map. V příloze je uvedeno vlastní šetření formou dotazníku. Hlavním cílem práce je poskytnout celkový přehled o této problematice. Kromě vymezení samotného termínu web 2.0 tedy především přehled aplikací a služeb, které splňují charakteristiky webu 2.0. Vedlejšími cíli je potom pomocí srovnání umožnit uživatelům výběr optimálního blogovacího systému, online textového editoru, nebo online mapy s ohledem na jejich požadavky.

Practical use of HTML 5 and CSS 3
Stehlík, Petr ; Pinkas, Otakar (advisor) ; Chudán, David (referee)
This bachelor thesis deals with two new languages, HTML 5 and CSS 3. They are probably the future of the Web as they contain many useful novelties, compared to their previous versions. At present both languages are still under the development, but they have already begun to be used in practice on the Web. The aim of this thesis was to find out the usability of HTML 5 and CSS 3 and to determine whether it is really worth to use them today. I worked it out by the theoretical research of languages possibilities and their application. To answer the question of functionality and usability of web sites written by these languages I compared their graphic design and functionality in different browsers. The result is that HTML 5 and CSS 3 can be effectively used today. There is only the question how to deal with the compatibility with older browsers. The fact that older browsers do not support new features can be bypassed by using different scripts. The bachelor thesis has theoretical and practical part. In the theoretical part I describe the most important features of HTML 5 and CSS 3. In the practical part I verify their usability.
