Information System for Translators Association
Neřold, Jan ; Chmelař, Petr (referee) ; Přibyl, Bronislav (advisor)
In today's economic situation, companies are exposed to pressure because of the demand for high quality services at low prices. The information system which makes key processes of a company much more efficient means an important support in reaching those demands. This thesis is concerned with the analysis of requirements, design, implementation, and testing of the information system for NK Translators, the translators association. The analysis and specification of the requirements were carried out with usage of UML. Web technologies like HTML, Javascript, PHP, and MySQL database system were used for implementation of the information system in the form of a web application. Finally, the implemented system was successfully submitted to a user testing.

A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Weiss, Petr (referee) ; Rychlý, Marek (advisor)
The thesis deals with an implementation of a program, which can make the data in relational database available as the standard storage Gentoo Portage with the assistance of FUSE library. The reader is initially familiarised with its structure. There is an analysis of the requirements on the program and the database described in the work. Furthermore, their proposal is given and in the penultimate chapter, there is described the implementation of the program. In the conclusion, there are all the outcomes evaluated including the comparison with the standard file system and further development possibilities of the project are also described.

Comparison of Properties and Performance of Object Oriented Databases
Kozák, Daniel ; Burget, Radek (referee) ; Zelený, Jan (advisor)
In this thesis, the reader learns basic models, which are use for storing data in database sys- tems. Next I describe a way, how to store objects in Java Language and explain expressions like object-relational mapping, reflection and introspection. After that, I will introdice some of existing implementation, which are use for storing objects in Java. Next I will explain testing methodology and make benchmarks of various implementation. In the end I will analyze a results of these benchmarks.

Object-Relational Framework for PHP
Hudec, Michal ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The objective of this work is to design and implement an Object-relational framework for PHP. This framework will be able to map objects to traditional relational database tables. In this work, an appropriate solution of metadata specification is presented. These metadata describe how an object can be store in a relational database. The framework itself is able to store, load and query any object data in relational database. This object-relational framework has been designed for simple portability among various database systems.

A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Mlích, Jozef (referee) ; Rychlý, Marek (advisor)
The thesis deals with implementation of a program which can, through the use of FUSE library, make data accessible in the relational database like the classical Gentoo Portage storage. First, the reader of the thesis becomes familiar with FUSE library itself. After that, the new data model is built based on the analysis of the Portage structure. The new model emphasizes especially dependencies of packages. The key implementation issues are also described in the next part. Finally, the thesis assesses outcomes achieved including comparison with standard Portage implementation and classical file system. The other possibilities of the project development are considered as well.

Database Performance Tuning
Paulíček, Martin ; Ruttkay, Ladislav (referee) ; Chmelař, Petr (advisor)
The objective of this thesis was to study problems of an insufficient database processing performance and possibilities how to improve the performance with database configuration file optimizations, more powerful hardware and parallel processing. The master thesis contains a description of relational databases, storage media and different forms of parallelism with its use in database systems. There is a description of the developed software for testing database performance. The program was used for testing several database configuration files, various hardware, different database systems (PostgreSQL, Oracle) and advantages of parallel method "partitioning". Test reports and evaluation results are described at the end of the thesis.

Application Database Layer Generator
Kuboš, Jaroslav ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This diploma thesis deals with the design and implementation of a framework for the database persistence layer development. This framework is easy to use while keeping the code elegance. It supports object oriented programming features such as inheritance and collections. Other features include versioning of objects and lazy loading. The object metadata are obtained through reflection provided by the .NET framework. The framework is not using any literal for identification (classes, attributes) even in object queries. Most of checks are done by compiler.

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.

Analysis of Data on Social Networks Based on Data Mining
Fešar, Marek ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The thesis presents general principles of data mining and it also focuses on specific needs of social networks. Certain social networks, chosen with respect to popularity and availability to Czech users, are discussed from various points of view. The benefits and drawbacks of each are also mentioned. Afterwards, one suitable API is selected for futher analysis. The project explains harvesting data via Twitter API and the process of mining of data from this particular network. Design of a mining algorithm inspired by density based clustering methods is described. The implementation is explained in its own chapter, preceded by thorough explanation of MVC architectural pattern. In the end some examples of usage of gathered knowledge are shown as well as possibility of future extensions.
