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.

Portable digital photo viewer
Poštulka, Petr ; Galamboš, Leo (referee) ; Kopecký, Michal (advisor)
The bachelor thesis describes the design and implementation of a portable digital photo browser. The importance was put on ease of extendibility and platform independency as the browser is primarily destined to be put together with photos on a CD or DVD. The browser offers display of various EXIF information, it allows the user to save additional information on chosen photos and perform searches on the basis of such additional data. At the same time, it offers a flexible user interface that could be customised to fit each user's preference.

Versatile O/R database manager
Plonka, Jan ; Říha, Antonín (referee) ; Kopecký, Michal (advisor)
The goal of this thesis is to design and implement a tool for the O/R databases administration. It places emphasis on maintainability, univerzality and extensibility of the solution. Without a need of installation, using web browser, it is possible to administrate remote databases from client workstation. The tool is easily extensible to support a new DBMS as well as a new object type within existing DBMS. The tool is intented for interactive schema management.

Benefits of object-relational technology
Paľo, Martin ; Říha, Antonín (advisor) ; Kopecký, Michal (referee)
Lately, object-relational databases have become increasingly popular. Compared to the traditional approach, they provide many new possibilities. This thesis describes the general requirements on object- relationaJ systems and the new object-relationaJ enhancement of Oracle, as well as similar enhancements of other well-known database systems and their comparison with the SQL: 1999 database standard requirements. An essentia1 part of this thesis is concerned with the comparison of the relational and object-relational in1pJementation of the student information system using the Oracle 9i database server.

Multidimensional Indexing for relational DBMS
Hoksza, David ; Kopecký, Michal (referee) ; Skopal, Tomáš (advisor)
The goal of this work was to implement a multidimensional indexing method into a database system and compare this method with existing implemtations of multidimensional indexing methods in current database platforms (MSSQL, Oracle, ... ). PostgreSQL was chosen for the implementation, because it suits the requirements of integrating own access methods in a modular way. The active development comunity which this platform unites has also played a part, since it assures help with problems related to the development. Last but not least, PostgreSQL was also chosen because its source code is accessible This was priceless in the effort of understanding the core of PostgreSQL (mainly work with memory), which has direct influence on user defined access methods, especially indexes. An already existing implementation of R-tree over object framework ATOM was used as an indexing method, which allows implementing of persistent tree structures. As a direct consequence of the work, not only has arised the implementation of Rtree in PostgreSQL, but also a generic framework which allows implementing external indexing in PostgreSQL with a minimum knowledge of how PostgreSQL works. The user of the framework implements his/her own persistent searchnig methods and connects these methods to the mentioned framework, which provides...

Web Content Management System
Lučanský, Ján ; Galamboš, Leo (referee) ; Kopecký, Michal (advisor)
This work describes web content management systems (CMS). It discusses what CMS systems are and what are general characteristics and requirements of these systems. Work further analyzes existing CMS solutions. The main part focuses on CMS system which is a product of author of this work. The system aims primarily on generating forms and form validation. It also specializes on processing data from these forms. In particular it focuses on their creating, editing and erasing. System contains also easily administrable tools for presenting these data. System is also capable of exporting these data to PDF, XML and CSV formats. In addition, system enables user to generate pie charts. A considerable part of the solution comprises tools for presenting data on public web pages.
