Information technologies for competitive intelligence
Hromádko, Jan ; Molnár, Zdeněk (advisor) ; Vejlupek, Tomáš (referee)
This thesis concerns technologies useful for competitive intelligence purposes. Its structure follows the scheme of the competitive intelligence cycle. For every phase of this cycle applicable techniques are specified, and possibilities of their software support are reviewed. The basic technique is deconstruction of competitive intelligence process to its basic components, and searching and exploring methods which can be used within those components. That means, above all, evaluation of usable software. The aim of my thesis is to make readers acquainted with principles of competitive intelligence, bring together different methods of work, and introduce useful technologies including particular software products. This thesis should also be helpful in deciding about methods in case of planning competitive intelligence, and what advantages and disadvantages it brings.

Informatization, media and development of society
Silovský, Michal ; Rosický, Antonín (advisor) ; Švarcová, Eva (referee)
The aim of this thesis is to create a comprehensive view on questions of development and influence of media on society and related formation and processing of information. This thesis should also enable the reader easier understanding and orientation in this topic. For that reason the thesis is divided into four main parts. The first section describes what is information, and the relation among data, information and knowledge. The second part is devoted to development and influence of information and communication technologies. It describes ways which enabled and enable to deliver information to its recipient and also related changes brought by these technologies. In the next chapter there is desribed what influences our relations within the framework of single nations and how media help to their convergency and linking. And the last part of this thesis includes an analysis of possible use and misuse when affecting broad masses of people.

Reaction to errors and alerts in ETL
Klimt, Roman ; Pour, Jan (advisor) ; Zajíc, Ján (referee)
This work deals with information systems called Business Intelligence (BI). Especially, it focuses on one part, whose task is to extract data from primary information systems. This stage is known as extract, transform, load (ETL). ETL is one of the most important stage in BI solutions because the quality of data depends on this stage. These data are used for all analyses and created reports. The goal of this work is to suggest solution for active projects, which are short of automated controlling mechanism. This mechanism should inform users of BI solutions about errors in data. If data from primary systems are in such bad state that ETL process is not able to match primary keys to them, the data are stored in special tables and are not used for future analyses. This is a very serious problem because analyses and reports based on the data may be misrepresentative. This problem must be solved by repairing the data in primary information systems. The administrator of primary information system has to know about the incorrect so that the data could be repaired. Therefore, an automated e-mailing system has been designed to inform about the incorrect data.

The influence of etalons on the data qualitiy in companies
Bukovský, Radim ; Slánský, David (advisor) ; Pour, Jan (referee)
This thesis is dedicated to all persons who are interested in information of the data quality (especially the Data Cleansing). Everyone who wants to get to know more about etalons, the essential part of the data quality, is welcomed. The insight into everyday activities of people working not only on creating and administrating of etalons but also implementing them on particular projects is prepared for everyone. The reader will also gain detailed knowledge of how etalons could help companies with decreasing their costs and how etalons can make better impression to company's clients through the data quality.

Data security in public accessible computers
Fikar, Vítězslav ; Klas, Jan (advisor) ; Lešák, Petr (referee)
This composition designs data security in public accessible computers in organization, which uses for it's work sensitive dates. The first part talks about reasons why was this problem selected and judges contemporary situation. In this part, there are mentioned targets of the composition too. Next part attends to theoretic level of solved problem. It takes in information about used methodics too. There are mentioned and described individual options, which can solve problem. Following part uses theoretic knowledges in practice. There is suggested data security in the organization. There are selected alertnatives and there are given reasons for each selection. At the end, there is summarized the solution and it is compared with original condition in organization.

Administrative data propagation in an information system
Vostatek, Filip ; Buchalcevová, Alena (advisor) ; Borguľa, Martin (referee)
The goal of this paper is to demonstrate a technologically superior solution of data propagation from an administration interface of an information system and formulate it as a design/solution pattern. That corresponds with the basic form of the text, where the design pattern is defined in 13 subchapters in a structure commonly used to define design patterns. The solution is introduced as a design pattern because of high reusability and because of the problem it challenges being so frequent in modern information systems -- that is also where the benefit of this paper lies.
