Integration of legacy databases to current information systems
Navrátil, Jan ; Kopecký, Michal (advisor) ; Helmich, Jiří (referee)
The goal of this thesis is to design and implement a framework to support Legacy system access. Legacy systems are databases that use incompatible and obsolete technologies and can not be easily abandoned. The framework allows the abstraction of application logic from database platform and will enable full or incremental migration to a new, modern platform in the future. The framework also considers the option of encapsulation of an existing legacy application into the new system as a black box. The framework is well configurable and extendable and is independent on database platform or data context. A system based on proposed framework has been succesfully deployed in a company. The system facilitated the migration of the company to a new information system with an entirely different database platform. The practice shows the viability of the framework design.

Data fusion
Janíková, Veronika ; Hovorka, Tomáš (advisor) ; Anděl, Jiří (referee)
This bachelor's thesis deals with a data fusion, which is a one of the possible solutions to the common problem of data availability in praxis. In the first part, practical use of data fusion, especially in marketing, fundamental algorithms and data fusion problems are discussed. The main part of this thesis deals with the so-called "unconstrained statistical fusion". Firstly, one of the possible processes of this type of fusion is described theoretically in detail. This process involves branching into four different types of data fusion. Next, a method of theoretical evaluating the quality of the general fusion model is designed using statistical indicators. The practical part of the thesis contents processes of four types of unconstrained statistical fusion and their evaluation which both are programmed in statistical program R. Furthermore, the fusion is applied to our artificially generated database and also to a real data collected in praxis by Czech public opinion research company Median. In the very last part of the thesis, the results of fusions applied to these two databases are interpreted, evaluated and discussed.

Linked Data Integration
Michelfeit, Jan ; Knap, Tomáš (advisor) ; Klímek, Jakub (referee)
Linked Data have emerged as a successful publication format which could mean to structured data what Web meant to documents. The strength of Linked Data is in its fitness for integration of data from multiple sources. Linked Data integration opens door to new opportunities but also poses new challenges. New algorithms and tools need to be developed to cover all steps of data integration. This thesis examines the established data integration proceses and how they can be applied to Linked Data, with focus on data fusion and conflict resolution. Novel algorithms for Linked Data fusion are proposed and the task of supporting trust with provenance information and quality assessment of fused data is addressed. The proposed algorithms are implemented as part of a Linked Data integration framework ODCleanStore.

Datová integrace ve velkých podnicích
Nagyová, Barbora ; Kučera, Jan (advisor) ; Chlapek, Dušan (referee)
Data Integration is currently an important and complex topic for many companies, because having a good and working Data Integration solution can bring multiple advantages over competitors. Data Integration is usually being executed in a form of a project, which might easily turn into failure. In order to decrease risks and negative impact of a failed Data Integration project, there needs to be good project management, Data Integration knowledge and the right technology in place. This thesis provides a framework for setting up a good Data Integration solution. The framework is developed based on the current theory, currently available Data Integration tools and opinions provided by experts working in the field for a minimum of 7+ years and have proven their skills with a successful Data Integration project. This thesis does not guarantee the development of the right Data Integration solution, but it does provide guidance how to deal with a Data Integration project in a large enterprise. This thesis is structured into seven chapters. The first chapter brings an overview about this thesis such as scope, goals, assumptions and expected value. The second chapter describes Data Management and basic Data Integration theory in order to distinguish these two topics and to explain the relationship between them. The third chapter is focused purely on Data Integration theory which should be known by everyone who participates in a Data Integration project. The fourth chapter analyses features of the current Data Integration solutions available on the market and provides an overview of the most common and necessary functionalities. Chapter five focuses on the practical part of this thesis, where the Data Integration framework is designed based on findings from previous chapters and interviews with experts in this field. Chapter six then applies the framework to a real working (anonymized) Data Integration solution, highlights the gap between the framework and the solution and provides guidance how to deal with the gaps. Chapter seven provides a resume, personal opinion and outlook.

System of Labour Market Information
Duspivová, Kateřina ; Hronová, Stanislava (advisor) ; Gottvald, Jaromír (referee) ; Galuščák, Kamil (referee)
The main aim of this dissertation thesis is to present a new system of statistical information concerning the labour market in the Czech Republic with respect to the theoretical background as well as to latest trends in the labour market statistics. The structure of the thesis is as follows. In the first chapter, there is a theoretical framework of the labour market introduced. This framework interlinks relations among employees and employers and is neutral with respect to all the economic schools of thought. Besides, I describe an actual state of the labour market statistics in the Czech Republic and evaluate its compliance with the theoretical research. The second chapter is focused on the state of the art concerning labour market statistics from the point of view of both data integration and comprehensive systems of labour market indicators. In the first part of the third chapter, there is a proposal of the new system of statistical information concerning the labour market that complies with both the economic theory and latest trends in the labour market statistics. The most likely advantage of the new system is the fact that all the key aspects of the labour market (i.e. employment as well as remuneration) are surveyed and evaluated together. In addition to the generally known indicators of both economic activity and remuneration, I propose new indicators of job creation, job destruction, hires, separations, job reallocation and worker reallocation. In the second part of the third chapter, there is a proposal of the integrated data source that will allow us to quantify all indicators provided that there are no legal restrictions concerning data integration in the Czech Republic. In last two parts of the third chapter, there are discussed both the main issues concerning the implementation of the system and the pros and cons of the system. There have never been quantified the indicators concerning job and employee flows using the linked employer-employee data in the Czech Republic, so the pilot results are introduced in the fourth chapter. It is obvious that using the new system, we could prove some hypotheses that were impossible to prove using standard set of indicators. In the last part of the fourth chapter, there are worker and job flows balanced with respect to the stock information concerning labour market in the Czech Republic. In the fifth chapter, I investigate the possibility of a wider use of the new system in order to be able to identify and analyse an array of labour market phenomena in more detail. The thesis brings a new insight to the dynamics of the labour market compared to the generally known basic set of labour market indicators. The systematic approach, based on a wider use of linked employer-employee microdata combined with new indicators, has the advantages of a higher information capability as well as of complying with the requirements of the academics.

Impact of the process and data integration on reporting efficiency
Sys, Bohuslav ; Šebesta, Michal (advisor) ; Bruckner, Tomáš (referee)
Nowadays, when the difference between failure and success is amount of the available information combined with exponential growth of the available information on web leads to rising need to track the quality of the data. This worldwide trend is not only global, but it affects even individuals and companies in particular. In comparison with the past these companies produce higher amount of data, which are more complex at the same time, all to get a better idea about the real world. This leads us to the main problem, when we not only need to gather the data, but we have to present them in such way, so they can serve the purpose for which they have been gathered. Therefore the purpose of this thesis is to focus on processes following the data gathering -- data quality and transformation processes. In the first part of the thesis we will define a basic concept and issues, followed by methods necessary for acquiring requested data in expected quality, which includes the required infrastructure. In the second part of the thesis we will define real-life example and use the knowledge from previous part to design usable solution and deploy it into use. In conclusion we will evaluate the design compared to the result acquired from its real-life utilization.
