Interactive Visualization of XML
Filus, Michal ; Stryka, Lukáš (referee) ; Chmelař, Petr (advisor)
This work deals with the problem of visualization of the XML documents. The goal of it was to receive information about XML documents, to become a knowledge of their structure, to know the languages for their description and finally, to create functional application for visualization. This work contains a short description of the programming language Java, it points out to their advantages and the availability of use in programming application which works with XML documents. The reasons of XML visualization are given in this work, which includes brief descriptions of existing applications for visualization, too. Thereafter the scheme of the application and description of its implementation is worked out in it. The result of this work is an application called XMLvisualizer created in Java programming language.

Interactive Visualization of XML
Seko, Martin ; Stryka, Lukáš (referee) ; Chmelař, Petr (advisor)
The main objective of this bachelor's thesis is to create an interactive visualization of data-oriented XML documents along with an implementation of such an application which is capable of displaying a document of this datatype. Application can generate schemas from an opened document in four supported languages: XML schema, DTD, RNG and RNC. It can also visually display this data in either tree or table format. Result of this bachelor's thesis is an application XMLspark, which is implemented as a multiplatform desktop application in the Java environment with the Swing GUI.

Demonstration of Support for XML in Database Systems
Dvorštiak, Matej ; Fiala, Jiří (referee) ; Zendulka, Jaroslav (advisor)
This thesis is concerned with XML technologies and XML support of database systems. Especialy with Oracle database. Support is descripted in this work. Desription is aimed to an Oracle XML DB architecture, XML data type, work with XML schema, storing and quering options of XML data in Oracle database. Practical part describes aplication, demonstrates XML support for learning proposes. Theoretical and practical parts are appended with examples and pictures for better understanding of described problematic.

XML Persistence in Relational Databases
Boháč, Martin ; Kolář, Dušan (referee) ; Chmelař, Petr (advisor)
The aim of this thesis is to create a client xDB database, which supports visualization and management of XML documents and schemas. The first part deals with the introduction of XML, XML schemas (DTD, XML Schema, RelaxNG, etc.) and contextual technologies. After that the thesis deals with the problem of the XML persistence and it focuses on mapping techniques necessary for an efficient storage in a relational database. The main part is devoted to the design and implementation of client application XML Admin, which is programmed in Java. The application uses the XML:DB interface to communicate with the xDB database. It supports storing XML documents to a collection and the XPath language for querying them. The final section is devoted to application performance testing and comparison with existing native database eXist.

Development of SQL/XML Functionality in PostgreSQL Database
Pospíšil, Tomáš ; Burget, Radek (referee) ; Chmelař, Petr (advisor)
The aim of this thesis is to propose a way to implement the missing XML functionality for the database system PostgreSQL. The second chapter discusses the theoretical paradigm with an XML-related technologies like Xpath or XQuery. The third chapter discusses the ISO SQL standards and describes the current level of implementation of native XML databases, versus traditional relational databases. The last part focuses on different approaches and it proposes a solution to implement the XML API to PostgreSQL, which validates XML documents against XSD, DTD and RelaxNG schemes. Next point is focused on XML indexing techniques and proposal of new index based on GiST.

Automatic Web Form Processing
Zdráhal, Petr ; Kolář, Dušan (referee) ; Burget, Radek (advisor)
This thesis deals with the web form automatization. It contains a short introduction to the HTML and XHTML markup languages and their facilities for the definition of forms. Next, there is a short overview of the HTTP protocol and XML markup language and a method of the form description using XML is proposed. The thesis contains a description of tool for creating XML file from HTML document and a description of a data sender tool using a CSV data file and an XML form description. Next, there is a description of the algorithms used in the implementation. The conclusion includes the achieved results and the improvements for the future.

Knowledge Data Discovery
Melichar, Ladislav ; Chmelař, Petr (referee) ; Jurka, Pavel (advisor)
The data mining is still little investigated area. This project is aimed firstly generally to the knowledge discovery from the structured data, especially from the datas in XML format. Furthermore the tree algorithm HybridTreeMiner is presented here with aim of its application for the knowledge discovery from XML documents. The practical part of this project is dedicated to the design of the conception for the algorithm integration to the mining system developed in FIT. This system is implemented in the programming language Java, it has modular structure and its parts communicate each other by means of the language DMSL. Reached results are presented and discussed in the end.

Graphical Editor of Simulation Models
Hořák, Jan ; Hrubý, Martin (referee) ; Peringer, Petr (advisor)
This paper contains brief introduction into modeling and simulation using Discrete Event Specified System (DEVS) formalism. It defines basic models (atomic and coupled DEVS) and shows how they are simulated. Examples of derived DEVS formalism like parallel DEVS or DESS are also presented. It is described how to create DEVS models using graphic modeling software and advantages and disadvantages of this approach. A short summary of known programs are also covered. Storing models in the XML language, validation of XML document and transformation capabilities by XSLT are discussed. The main section is dedicated to the design of a graphic editor for simulation models inspired by design patterns including classes for canvas, model representation, export module interface and main application. The XML document used for storing DEVS models and simple DEVS simulator are also described. Implementation section presents used programming libraries, reasons why they have been used and their advantages and disadvantages. Paper ends with an example of a simple DEVS model created by implemented graphic editor for simulation DEVS models.

Scientific Web Portal Generator
Růžička, Štěpán ; Vyskočil, Michal (referee) ; Smrž, Pavel (advisor)
In this document I am talking about dynamic web application, which I am making via Ruby on Rails, XML, MySQL and AJAX technology. Introduce describes, why I have chosen this job, and what you can find in this document. Next part is about Ruby on Rails and XML, where I am describing how to use REXML library and what it offers to you. There are some examples to better understanding that. Continuing with describing libraries, which can offer dynamic, sound and some other effects. Prototype and script.aculo.us are described there and some examples as well. Semifinal chapter is about Web portal generator in general at first and next about single steps when I was working on my application. In last one chapter I am trying to look on my application from user's point of view. I am describing the way, how I tried to make application better for usual user. I joined some reactions from persons who had the opportunity to work with my application. Document terminates by resume of gained experiences.
