Diploma thesis describes basics terms of data visualization elements in the theoretical part. There are the following main topics covered -- importance of data visualization in business management, description and application of main chart types, design and usage of complex visualizations (dashboards), key features of modern data visualization technology. Theoretical grounds are then applied on real examples from different companies in order to show how managers can benefit from good data visualization techniques. Examples from significantly different areas were chosen -- financial management, operations management, analysis of process efficiency.

This diploma thesis deals with the Business Intelligence reporting tools and more especially with their data visualization capabilities. There are a lot of different reporting and analytic tools focusing for example on ad-hoc query, tool for creating dashboards or scorecards, visual discovery tools and advanced analytical tools for data mining etc. This work, however, is focused especially on selected enterprise reporting tools and data visualization tools as well as their possibilities of data isualizations, i.e. using different types of graphs and other possible advanced data visualizations. The Business Intelligence fundamentals together with the possible the reporting and analysis visual outputs are described at the beginning of this diploma work. The reporting itself is also putted into the context of the Business Intelligence solution. The next section is focus on the visual possibilities of data visualization in BI reporting tools. It means that I created the list of possible BI data visualizations with the detail specifications and showing examples on each of them. After this part, there are shown proper data visualizations for each of the selected BI domains, like finance, sales, marketing and human resources. This output belong to one of the main contributions of this work and also could be practically useful in the process of report creation and selection for Clever Decision's BI reporting needs. In the next chapter I compare the visual possibilities for each of the selected BI reporting tools according to Gartner. To this purpose the official documentations will be used as well as my personal experience gained from using some of selected reporting tools. In the last section there are detail views for each of two selected advanced data visualizations including a detail specification on each of them as well as his possible usage in practice and possibilities for further extension as well. The source of information in this section will be professional electronic resources focused on data visualization, design and so on.

The main objective of the diploma thesis called "Analysis and design of BI Reporting and Dashboards Survey" is to analyze the main principles of Business Intelligence and Corporate Performance Management approach with a focus on performance reporting and dashboards, and to design a survey form for BI Reporting and Dashboards Survey which will focus on the current state of the reporting and dashboards in European enterprises. The final design of the market survey form is based on the identified key areas of the topic and is created by using the basic principles of statistics which help to compose successful market surveys. It represents the main input for the conduct of the quantitative market survey planned to be realized in the summer of 2014. The first part of the diploma thesis represents the theoretical baseline for the analysis of the key areas of the survey's content. This part includes introduction to the BI and CPM principles (chapter 2) followed by the identification and definition of key elements of successful BI reporting and dashboards (chapter 3). The last chapter of this part (chapter 4) summarizes the key principles of statistics leading to beneficial composition of market surveys. The second, practical part of the diploma thesis (chapter 5), presents the overall design of the BI Reporting and Dashboards Survey. This design includes scope, objectives of the survey, profile of respondents, and specification of the question form with predefined range of possible answers to each individual question. The final design of the question form is also available in Appendix 1 in MS Excel file. This diploma thesis emphasizes the importance of the effective performance reporting and the beneficial use of dashboards in organizations and outlines the key areas of those topics which business representatives should focus on. Another benefit of this thesis is the prepared question form itself which might bring interesting and valuable findings about the current state of BI reporting and dashboards implemented and used among the European countries.

The thesis's primary focus is the visualization of data in Business Intelligence with broader ramifications because the framework defined here will be useful for making any design layout. It describes the cognitive aspects of perception for visualization and with this understanding the thesis will be able to summarize the rules which are necessary for right and functional design. The goal of design is to provide the information in the most understandable way. The author has surveyed individuals to find out how people are familiar with the rules for designing and the style of visualization that people prefer. The last part of this thesis is focused on the implementation of the findings with the ultimate goal to suggest a new BI reporting system. Being able to list and verify the rules of visualization on the path to implementation is the main benefit of this work.

The aim of the work is create and describe solution of automation and visualization of project boards in the specific manufacturing company. Methods and tools of Business Intelligence are used in this process. Project board is arranged summary of information, which is part of the monitor, in this context. There is for example information about produced pieces, the cost of poor quality, project Scorecard, downtime analyses, bottleneck of project, and so on. The theoretical part is dealing with description methods and components of Business Intelligence and serves to explanation basic principles on the basis of which are formed data staging area, data warehouse, OLAP cubes and dashboards. The main emphasis is on the practical part, in which is detail describe process of data elaboration from source data, which are taken primarily from MS Excel files, till data visualization in the form of dashboard. As software workspace were selected Microsoft products, specifically SQL Server Management Studio, Visual Studio and Excel which has been mentioned before. The main output is solution that will gradually fully replace paper project boards. This solution also brings both financial and time savings in the creation and managing project boards, because this process is automated.

This thesis solves the area of data visualization in Business Intelligence. We live in a time when the amount of data grows turbulently. These data need to be processed into a form with added value for management and business objectives of the company. The first task is to adjust the data into the required format, the second task is to choose the appropriate visualization so that the data are providing the highest value. This work deals with data visualization and its main aim is to introduce a different approach to data visualization, which has a higher added value than conventional visualization methods used in dashboards and reports. First of all, theoretical part is describing data area (including the trend of Big Data) and reporting (chapter 3). Followed by chapter 4, which is enriching the reader with the information about the need to deal with data visualization and also with the design theory of visualization components. The theoretical part is finished with fifth chapter. It deals with current trends in the field of data visualization and Business Intelligence and also introduces D3.js library as a tool for creating interactive and efficient visualization components. The practical part is offering suggestions for interactive and dynamic visualization of input data (chapter 6). It presents a convenient way to choose a visualization component with greater value than the traditional static component in the form of a graph or table. Proposals contained in D3.js library are presented to the reader. Chosen components according to the author are interesting from the view of design and, if properly used, offer an innovative approach to data visualization. For purposes of practical examples of visualization, author is using D3.js library and open source tool for Business Intelligence from Pentaho. Practical example is part of the final chapter 7.

The thesis deals with problematics of tools marked as Self Service Business Intelligence (SSBI) which is paid close attention by its users as well as producers due to expected progressive growth of this trend. Two products are evaluated: SAS Visual Analytics and IBM Cognos Analytics, both tools are evaluated by their extent of user´s autonomy and support of data visualization. Basic principles and concepts connected to the area of business intelligence are defined in theoretical part of the thesis. The problematics of data visualization is introduced and trend of self-service business intelligence is discussed with analyzing its benefits as well as restrictions. Technological factors which helped to fast development of SSBI are mentioned as well. A methodology has been created within practical part of the thesis. It is enforceable for any other tool from the family of SSBI and it is possible to assess the extent of support within observed categories through this methodology: Using information, Creation of information, Creation of sources and Visualization. A set of criteria on basis of which the evaluator can create evaluation form corresponding to his/her needs was defined for each of the stated categories. Usability of the methodology is illustratively demonstrated at mutual comparison of chosen modules of both tools while those parts are sufficiently described before the evaluation itself.

This master's degree thesis focuses on the issues of visualization formerly preprocessed business and technical metadata in a business environment. Within the process of elabora-tion and usage of the collected data in the company, it is necessary to present the data to the users in a comfortable, comprehensible and clear way. The first goal of this thesis is to describe and to specify the term of metadata in the field of theory and on the level of busi-ness, their main structure, their occurrence in a non-visual manner and related places where we can find metadata in the heterogeneous business environment. This part also includes a short introduction to the usage of metadata that is related and originates from business in-telligence and a description of Company encyclopedia that can syndicate these resources for further utilization. When defined, the sources, destinations and purpose of technical and business metadata can be used in the second part of the thesis -- this part is aimed at model-ing the use cases for the visual component that can be applied to business and technical metadata. Use cases will be focused on the roles of the users that will use this component and to discover the primary demands and requirements of these users and the functionality that will be indispensable. After the use cases are defined we can process to the next stage of visual component development -- the data must be visualized itself and we have to find proper means to achieve this with user experience being the main focus. Then we have to encapsulate the visualization with a graphical user interface that will meet the requirements and demands of the users' roles specified by the use cases section by prototyping. Lastly, the results of the previous chapters are used to prototype the visual component suitable for a web environment which is based on principles of reusability, data-driven approach, and uses modern web technologies such as framework and library D3.js, HTML5, CSS3, and SVG.

Experimental investigations of liquid helium flows Selected turbulent flows of He II, the superfluid phase of liquid 4 He, are inves- tigated experimentally. The second sound attenuation technique is employed to directly probe the tangle of quantized vortices, thin topological defects within the superfluid, while relatively small particles made of solid hydrogen are dispersed in He II to visualize the overall flow of the liquid via the particle tracking ve- locimetry. Considering the known particle-vortex interaction mechanisms, steady thermal counterflow in a square channel is investigated. Significant inhomogene- ity of the vortex tangle density along the channel height (near the flow-generating heater) is shown to develop. The means of energy transport in turbulent flows of He II are found strikingly different from those taking place in turbulent flows of viscous fluids. Moreover, individual particles in counterflow are observed to intermittently switch between two distinct motion regimes along their trajecto- ries. The regimes are identified and qualitatively described. Steady counterflow jets in He II are realized and the spatial arrangement of the underlying vortex tangle is explored. Finally, macroscopic vortex rings are thermally generated and observed in He II. A method for tracking their...

The aim of the diploma thesis is to analyze the current state of creation of management reporting, its contribution to a company and to create a proposal for improving and expanding awareness of reporting in a company.
