Data archiving using blockchain technology
Řihánek, Tobiáš ; Sikora, Marek (referee) ; Člupek, Vlastimil (advisor)
This thesis dealt with the issue of data archiving. The aim was to explore the possibilities of using blockchain technology to address the security aspects of digital archiving, and then to design and implement an application that uses blockchain to secure data integrity. First, a theoretical analysis of both archiving and blockchain technology was conducted. Next, a web application was designed that uses this technology to detect integrity breaches. Based on the design, a system consisting of a web application written in JavaScript and an archiving application and a validation application written in Java was implemented. These applications communicate with each other and create a secure archiving system using blockchain. The functionality of the system was demonstrated and its security was tested.

Services over digital archives in science and research
Lochman, Martin ; Bratková, Eva (advisor) ; Papík, Richard (referee)
The thesis focuses on various information services over digital archives and institutional repositories in the area of science and research. It aims to ascertain these online services and introduce, analyse and assess selected examples in detail. Their quantitative as well as qualitative features are emphasized - The work is logically divided into four chapters. The first one defines the basic terminology and outlines the contemporary status of scholarly communication on the Internet. The second chapter introduces a comprehensive list of services as well as their suggested typology. The third chapter constitutes the core of the thesis and presents the descriptions and analysys of the selected services. The fourth final part includes the comparison of their relevant parameters, final assessment and the perspectives of their future development. Keywords digital archive, institutional repository, scholarly communication, information services, OAI- PMH, metadata harvesting, open access

Creation of family trees by using modern ICT technology
Hošek, Martin ; Samec, Marek (advisor) ; Jelínek, Ivan (referee)
This bachelor's thesis deals with the topic of family trees, their creation by using electronic resources, software and web resources and ways of looking up the information about the history of the family. The aim is to create a methodological guide, how to start with creating a family tree and how to create it. In the first part, important concepts are theoretically defined as well as methods for looking up necessary information. The second part describes the procedure for creating a family tree. The final section summarizes how to proceed during the creation of family tree and what to avoid.

Tuning and testing of database systems for needs of digital archive SAFE III
Pobuda, Tomáš ; Chlapek, Dušan (advisor) ; Štrunc, Martin (referee)
Thesis deal with tuning of database Oracle, which is used by digital archive SAFE. In the concrete deal with setting parameters of database. It is divided to three parts. In first part it characterizes factors that influence performance of database. In second part it describes possibilities of tuning and setting Oracle database. In third part it is first introduced digital archive SAFE, after that it is chosen suitable testing tool for workload generation and described test scenarios and last are performed tests and compared results at different database database settings. Goal of thesis is description and trial tuning of Oracle database, which is used by digital archive SAFE. Other goal is test of files inserting into digital archive at different settings (saving to the database, on file system). These goals are achieved by testing tool workload generation and compare response time at different settings. Contribution of this thesis is above all trial of tuning Oracle database, which is used by digital archive SAFE. Document can be used like handbook for implementatory of tested implementation of digital archive SAFE.

Implementation of the digital archive in multinational company
Žižková, Veronika ; Kunstová, Renáta (advisor) ; Maryška, Miloš (referee)
The goal of this work was to process the problematic of the digital archive -- implementation of the digital archive into the payroll system include completion analysis of effectiveness. A part of this diploma work includes detailed analysis of the effectiveness of the digital archive used in the company with the international activity, from its benefits till its cost that relate with the implementation of the digital archive. In the work it is described the problematic with the implementation itself in praxis, it is explaining the digital archive from the technological aspect in detail, even from the users side. It is described the process of extensive analysis of the digital archive in the company and comparing with the manual archiving of the data, with the help of the multi-criteria decision making. The goal was to find out if the implementation of the digital archive has got such a proofing value and met the expectation of all ADP managers. For the calculation there was used the method the determination of the weight of certain criteria and the levels of realization. The method was used for analyzing of the benefits, analyzing of the cost came from actual measurable units. Then there were used three methods for the comparison of the costs and incomes: creation of the quotient of costs and incomes, the graphical scheme of costs and incomes and transformation of the costs into incomes and defining the value of benefits. This whole process of calculation was repeated twice. In the first part there were used my own experience and knowledge and the weight was chosen by my opinion. Then In the second part there was used a question-form that was given to the German clients.
