Support of Information Extraction from Structured Text
Kliment, Radek ; Petřík, Patrik (referee) ; Křivka, Zbyněk (advisor)
This Bachelor thesis deals with the way of information extraction from a structured text. The application converts the text from supported formats into the XML representation that is used for queries and then, corresponding output is created. In this thesis, particular formats of input files are described including the way of their conversion into the XML. The essential part explains the application functionality and implementation including short user manual.

A Tool for Editing and Comparing LMF Dictionaries
Fešar, Marek ; Kouřil, Jan (referee) ; Smrž, Pavel (advisor)
The diploma thesis presents dictionary formats and focuses on principles and semantics of data storage using Lexical Markup Framework. Contains information on relationship between the framework and Data Category Registry, which is part of the ISO standard for further dictionary data specification. After that, the Oracle Berkeley database system for XML document storage is mentioned followed by approaches for addressing documents and its portions. Methods for dictionary comparison are being described as well as grouping and changing dictionary content. Help on the process of dictionary modification must be provided to the user in the way of showing expected features, relevant to the selected element.

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.

Support for XML in Microsoft SQL Server 2008
Bábíčková, Radka ; Burget, Radek (referee) ; Zendulka, Jaroslav (advisor)
This thesis is focused on XML and related technologies. The XML language is directly linked to the databases and its support in databases. The overview of the XML support provided by various database products and systems are presented in this work. Support in the MS SQL Server 2008 is discussed in more detail starting with the mapping of relational data to XML and vice versa to support of the XML data type and work with it through XQuery. Also some indexing techniques are briefly presented. Finally, the support in MS SQL Server 2008 is demonstrated by means of a sample application, which verifes the theoretical knowledge in practice.

XML Transformation and Persistence in Relational Database
Hernych, Radim ; Rychlý, Marek (referee) ; Chmelař, Petr (advisor)
This master's thesis deals with problems of effective storage and querying of XML documents in A relational database. In the first part of this thesis XML and related technologies are described, with emphasis on languages for XML Schema definition and it's querying. Then an XML mapping method based on Hybrid method and XML Schema is described here. Hereafter the design and implementation of a native XML database front-end for object-relational database is described. Designed front-end allows storing and querying of XML documents into the underlying database. The last part contains results and evaluation of performance tests of the implemented system.

Native XML Database with XQuery Interface
Losert, Jakub ; Jurka, Pavel (referee) ; Chmelař, Petr (advisor)
The aim of this Thesis is implement Aplication Programming Interface (API) with support of XML native documents. First part deal with introduction of XML model and with this markup language related technologies. Alfter that the thesis describe individual XML native databases solutions and focus to issues of persistence XML data stored in relational databases, analyse mapping methods applicable to their relational model. After that the thesis describe design and implementation of the API, which afford a resources for XML documents data holding and manipulating in relational database system. The final section of this thesis is assignment to aplication tests and evaluation of results.

Comparison of native XML databases in terms of XML data management
Čižinská, Martina ; Palovská, Helena (advisor) ; Kosek, Jiří (referee)
The basis of my work represents a research focused on the problematic of native XML databases. The main goal is to draw comparison between the selected database systems in a sphere of user control and management of XML data. Database products are tested via XMark benchmark test using its XQuery queries and testing XML data. Final comparisons and recommendations for use are based on the concluding evaluation and findings. The results of research may improve orientation in solved problematics. They could help with the selection of a suitable database product to store XML data.

Utilization of XML databases for retrieval of data-mining specifications
Marek, Tomáš ; Kliegr, Tomáš (advisor) ; Kosek, Jiří (referee)
The aim of this work is to create a querying system in analytical reports stored as PMML documents. These PMML documents are stored in native XML database, because these documents are structured as XML documents. Selected XML database is available for free and its resources and means meet the proposed solution. Also searching algorithm is created to search these documents by means of XQuery language. Inasmuch as searched data have the character of the XML data the use of language for querying XML data suggests. In terms of the use of the XQuery language structure of PMML document was explored and data links in these documents was used to ensure proper search results. Results of the search are association rules from these analytical reports stored in PMML documents, requests of the search are attributes to be in the rules, their values and other limits of the search. So that the whole system is complete and could be fully used, it is necessary to create a communication environment through which the work with stored data is performed. For this purpose, Java and REST(ful) architecture for creating applications are used.
