Database schema documentation generator
Berka, Lukáš ; Hoksza, David (referee) ; Kopecký, Michal (advisor)
The bachelor thesis discribes design and implementation of database schema documentation generator. It uses Schemagic application to create wellarranged documentation in user-defined output format. Schemagic is used to load information about schema into a XML document. For output documentation HTML, PDF, Postscript, RTF, DocBook and FO (XML file of formating objects) formats are supported. The Gendok application also generates some graphic information, e.g. graphs of dependencies between tables.

Visualizer of the Web Structure
Halaša, Michal ; Galamboš, Leo (advisor) ; Kopecký, Michal (referee)
Web crawler generates web structure including the notes (anchor texts) which belong to individual links.Thesis target is to analyze and implement method for visualisation of this oriented graph structure. Implementation language platform is Java. Implementation must be able to denamically change the view according to defined criteria - showing only certain links or web pages. Grouping of links or web pages must be also available.

Visualization methods utilization for document searching by user preferences
Jenček, Petr ; Kopecký, Michal (referee) ; Vojtáš, Peter (advisor)
The aim of this work is to study possibilities of presentation of document search results according to keywords given by a user using sociomapping method. Both web search and locally stored documents search will be our interest. We'll create document clusters from such results using one of the clustering algorithms and measures of keywords similarities. These clusters will be input data for creation of direct, or indirect sociomap. Finally we'll compare results of the clustering algorithms from several points of view.

C++ Object Persistency Using Object/Relational Databases
Čermák, Petr ; Skopal, Tomáš (referee) ; Kopecký, Michal (advisor)
This thesis deals with design and implementation of a library providing object-relational mapping services for programs written in C++. Emphasis is put on its transparency and ease of its use. To achieve these goals the library uses GCCXML, a XML output extension to GCC. GCCXML helps the library to get description of the class model used in the user application and to simulate the reflection. For the mapping purposes, new object-relational database features are discussed and a new mapping type is proposed. Implementation of the library is based on three related projects - the POLiTe, POLiTe 2 and IOPC libraries. The proposed and implemented library unifies them into one solid, flexible and extensible platform. Thanks to its modular architecture, the resulting library can be used in several configurations providing subsets of implemented services - database access, reflection and object-relational mapping.

Effective and transparent data backup
Milan, Ján ; Obdržálek, David (referee) ; Kopecký, Michal (advisor)
The thesis describes the implementation of an effective and easily manageable backup system for OS MS Windows XP and newer. Emphasis is put on the simplicity of defining objects to be backed up. Effectiveness has been attained by backing only those files up, which has changed since last backup cycle. Unlike most other backup systems, delta files are used during transferring into remote server. The main contribution of this thesis is unique mechanism used to create copies of old versions of files. These are created by moving the files itself into temporary storage, when the request to overwrite them arrives. Moved old versions of files are used as an input for creating delta files. Designed solution contains user interface which enable comfortable backup of user data onto a removable disk. However it may be used also as a base for backup onto a remote computer. The description of file system filter development among others summarizes many issues and best practices for developing in kernel mode and may be used as an introduction into this area.

Requirement management tool
Jelen, Martin ; Hoksza, David (referee) ; Kopecký, Michal (advisor)
Managing requirements for software projects is a key task throughout the whole lifetime of the project. Recognizing this, it is the goal of the bachelor thesis to design and implement a tool that simplifies and automates requirements management and provides a clear view of the current state of managed projects as well as their history. It is not intented as a single project management solution but rather to be used with other specialized software. Implemented is the ability to capture the managed project's structure and multiple types of requirements (e.g. functional, performance, usability) with clearly defined relationships. The project's representation can further evolve, all previous versions are stored and changes can be reviewed. Data presentation is accomplished with multiple views of requirements and allows to trace changes through the relationships. Finally, the gathered data may be exported in either structured form for further transformation or as user-readable reports. Requirements, their atributes and types, as well as views on the requirements are highly configurable to provide support to projects independent of development methodology used - from agile approaches with minimum administrative documents to more formalized processes such as RUP.

Virtualisation of Surveillance Systems
Koňas, Jakub ; Žemlička, Michal (referee) ; Kopecký, Michal (advisor)
Title: Virtualisation of Surveillance Systems Author: Jakub Koňas Department: Department of Software Engineering Supervisor: RNDr. Michal Kopecký, Ph. D. Supervisor's e-mail address: Michal.Kopecky@mff.cuni.cz Abstract: This thesis studies the procedures in the field of security, building and lifesafety management focused at rising necessity of securing buildings in geografically large areas. The opening chapters of the thesis explain the principles of facility management relevant to security and present current progress in the field. It creates new comprehensive source of information based on the experience of security specialist that Czech languge lacks. The following chapters define new terms in the field of security - large area (LA) and securing the LA (SLA) - and specify the essential qualities of SLA systems. Subsequent part of the thesis discusses possible architecture of the SLA system and proposes own solution based on ideas of service architecture and OPC. The thesis contains partial implementation of the crutial element of the framework - the virtual device. The final chapters demonstrates needed qualities of the framework using its sample application. Keywords: surveillance system, security, large area, virtual device, framework

Précis querying over relational data
Štuller, Július ; Kopecký, Michal (referee) ; Pokorný, Jaroslav (advisor)
Free form of querying a database belongs among basic methods of text processing. In the past, a number of attempts appeared to use this style of querying also over a relational database (e.g. system BAROQUE [3] in 80ties). Authors of [1] introduce a new technique of a free querying, in which complex queries in SQL over a relational database are automatically generated. As an answer they provide more relations than one as it is usual in relational database languages. User preferences are considered, e.g. according to his/her profile. The goal of thesis is to design and implement a prototype of a system that offers such functionality on the top an existing relational DBMS.
