The aim of this thesis is to standardize project design of data centers and to define the critical points in its implementation. The introduction describes the types of data centers . The next part describes the legislation and standards, which are needed to follow in the implementation of the data centers. It is also designed topology of the data center, which is divided into TIER I -IV in relation to the availability of services . The next section defines and describes the critical points in the implementation of data centers (energy center, cooling system, fire protection system etc.). On the basis of standards and critical points have been proposed general methodology for dealing with design data centers. The proposed methodology is demonstrated on already constructed and operated commercial data centers.

This diploma thesis concentrates on businessmen using a data box to communicate with state authorities and business partners. It identifies and quantifies advantages and disadvantages of this service and also proposes certain improvements so that the system of data boxes can be used to its full potential. The thesis has two parts - the literature research part and the original research part. The literature research part characterizes the development of e-government in the Czech Republic, defines basic terms of the data box system and describes its functioning. The original research characterizes the ways of working with data boxes in sample subjects. Based on this research the thesis proposes possible improvements including their economic interpretation.

The main topic of the diploma thesis is the development of data boxes in the Czech Republic from the very beginning to its current valid legislation. It focuses on the law No. 300/2008 on electronic operations and authorized conversion of documents. This law has integrated the data boxes into the Czech rule of law. Besides, attention was given to the main terms related to the electronic communication via data boxes (data message, data box, establishment of a data box, types of data boxes). Furthermore, in the thesis is also mentioned the project of data boxes at the town hall for the region of Prague 13. The possibility of submission a request on establishment of a data box for individuals has also been discussed. In the conclusion were given remarks and recommendations related to the issues.

Diploma thesis deals with the topic of information integration. The aim of the thesis is to characterize the market of IT resources for supporting Enterprise Information Integration. To achieve its objective, it will be first introduced the area of EII. The results will serve for formulating criteria that will be used to analyze the market of these IT resources. Based on the formulated criteria, there will be evaluated market offerings and then specified its key characteristics. The author's contribution to this work lies in the submission of a comprehensive description of the Enetrprise Information Integration.

The goal of this thesis is to research to role of data profiling in data quality management and the quality of existing data profiling SW tools. The role of data profiling was based up an analysis of the general methodology of approach to the management of data quality. I've compiled an own methodology for the analysis of data profiling tools. This methodology focuses on three main aspects: Technical requirements, User friendliness and Functionality. Based on the methodology the best SW solution for data profiling was chosen. General shortcomings of tested SW tools were also analysed.

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.

Companies in these days deal with underlying issue that concerns about questions how to manage volume growth of corporate data needed to decision making processes and how to control credibility and relevance of derived information and knowledge. Other questions deal with problem of responsibility and data security that represents potential risk of information outflow. The Data Governance concepts provide comprehensive answer to these questions. However, making a decision on implementing a Data Governance program is usually triggering many other problems like setting up environments, making determination of project scope, allocating capacity of data experts and finding one's way in non-uniform Data Governance concepts offered by various IT vendors. The aim of this thesis is to draw the unified and universal implementation process that helps with setting up DG projects and makes certain conception about how to run these projects step-by-step. The first and the second part of the thesis are dedicated to describe principles, components and tools of Data Governance and also methods of measuring data quality levels. The third part is offering concrete approach for successful implementation of Data Governance conception into corporate data environment.

This thesis deals with the area of Business Intelligence and especially the part of data quality. The goal is provide an overview of data quality issue and possible ways the data can be shown to have better and more engaging informative value. Another goal was to make a proposal solution to the visualization of the system state, particularly the section of data quality, at the concrete enterprise. The output of this thesis should provide a quideline for the implementation of the proposed solution.
