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.

Editor of Relational Tables
Boháč, Martin ; Křivka, Zbyněk (referee) ; Šárfy, Martin (advisor)
The thesis describes development of editor, which allow users to effective browse and manage data of database. It advert used technoligies and possible alternatives accesible on market. Next part attend to describe of implementation and methods of solving implement problems. The rest of this work is set to posibilites of extension and using in different departments

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.

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.

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.

NNTP Server as a Windows Network Service
Loupanec, Josef ; Ráb, Jaroslav (referee) ; Očenášek, Pavel (advisor)
This work includes specification and analysis of requirements, design and implementation of the internet news server. The server controls newsgroups and associated news. It provides availability of the articles by NNTP protocol and HTTP protocol (by web interface). The server supports a user authentication and an optional proxy mode, when all NNTP requests are resent to another remote NNTP server. A mechanism that provides news-downloading from remote NNTP servers and performs distribution function is included too. The application is designed to run on MS Windows NT (and higher version) as a NT service. The server is configurable by a graphic user interface. The work also includes theoretical information needed for successful accomplishment of the above-mentioned requirements.

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.
