Data warehouse based on IBM technologies and its possibilities
Snítil, Jiří ; Pour, Jan (advisor) ; Novotný, Ota (referee)
This diploma thesis deals with the analysis of advanced data warehouse concepts where three advanced data warehouse concepts are analysed and their selection is justified. The first selected advanced data warehouse concept is a method of capturing data changes from sources system Change Data Capture (CDC). The second concept is the historization of captured data into historical data collection. The third concept is the application of analytical functions directly within data warehouse technology. A new testing environment has been created to analyse these concepts where the main database system Netezza available in IBM PureData System for Analytics, powered by Netezza technology (PDA), is utilised. This testing environment allowed all selected advanced data warehouse concepts to be reviewed. An impact of the application of these advanced data warehouse concepts has been analysed based on results from the testing environment and practical insights, particularly regarding potential advances. In the testing environment it was verified that all analysed advanced data warehouse concepts are applicable in a data warehouse. In the first advanced data warehouse concept was chosen LiveAudit mapping as appropriate for further data processing, when with this mapping it is possible to unambiguously determine the state of data in a source system at any point in the past. The second advanced data warehouse concept established that data acquired from LiveAudit mapping is possible to effectively process into historical data collection. Based on these findings, there was proposed generic solution of processing data from source systems. In the third advanced data warehouse concept was also proved, that it is possible to work in native analytic environment RGui and move the computation itself into data, which is located in the data warehouse, without the necessity of migration of these data. Further, it is possible to develop and use a new analytic function written in C++ language directly into the technology of the data warehouse.

Practical Application of ITIL Methodology in the Field of Banking Applications Support
Tenzer, Adam ; Pour, Jan (advisor) ; Basl, Josef (referee)
The diploma thesis deals with the practical application of a wide-spread service management methodology ITIL in the banking applications support environment. The main goal of the thesis is to formulate recommendations which should in the future contribute to quality improvement and overall productivity increase of the application support in the chosen multi-national company. The theoretical part of the thesis includes a detailed multi-perspective literature review. Based on the review, benefits of using ITIL, its adoption rate across IT operational departments, implementation approaches and possibilities, or perceived shortcomings are identified. ITIL architecture characteristics are provided and IT service management is briefly explained. Furthermore, an agile methodology Kanban is introduced and it is clarified, how it can be seen in the context of ITIL and how it can be used for its extension.In the practical part the chosen company is described at first. Thereafter, an analysis of a current (as-is) state of the application support process is performed. The analysis relies on the data collected from internal documentation, interviews and personal observations. The data is used as a basis for a process model and SWOT analysis. Then an internal reorganizational project based on Kanban principles is described. The most important chapters contain two sets of recommendations. The first one proposes possible improvement steps for the internal project. The second one focuses on selected IT operations management parts (event management, incident management, request management, problem management). Key characteristics are described, metrics are listed, and finally recommendations for identified weaknesses in the chosen company are formulated.
Oracle database systems administration
Šilhavý, Dominik ; Pour, Jan (advisor) ; Štalmach, Tomáš (referee)
Master's thesis with the name Oracle database systems administration describes problems in databases and how to solve them, which is important for database administrators. It helps them in delivering faster solutions without the need to look for or figure out solutions on their own. Thesis describes database backup and recovery methods that are closely related to problems solutions. The main goal is to provide guidance and recommendations regarding database troubles and how to solve them. It is shown, how to interconnect these methods with database backup and recovery. Targets were reached by backup methods analysis, real word problems simulations and resolutions were shown as well. The main contributions are practical examples of real word issues, which can be faced by database administrator, including different ways how to solve them. Thesis contains materials and based on them an administrator can decide for the best suited backup and recovery configuration and strategy in a company. Another important contribution was a creation of knowledge objects on Thesis is separated into three logical units. First six chapters delimit thesis borders, contain bibliography research and introduce into Oracle database issues, including methods for database backup and recovery. Second practical part aims at backup and recovery analysis and includes database troubles simulation and their resolutions. The last part is dedicated to knowledge objects on
Methodological framework of system analysis for the development of the banking system
Rahm, Vladimír ; Pour, Jan (advisor) ; Štalmach, Tomáš (referee)
The diploma thesis deals with software development methodologies and modeling tech-niques that can be used for the development of core banking system. The main aim of the thesis is to design a methodical framework of analysis which takes into account the spe-cifics of the banking environment and the development of the core banking system itself. The thesis is divided into three parts. The first part is devoted to the specifics of core banking development, analysis of life cycle software models, software development methodologies and their suitability for the development of the core banking system. The suitability of individual software development methodologies is assessed by the METES system for evaluation and selection of methodologies. The second part is focused on modeling techniques and notations, especially on UML, BPMN notation and CASE tools. The third and final part of the thesis contains a design of the methodological framework of analysis for the development of a core banking system focusing on the specifics of the banking environment.
Comparison of commercial deduplication solutions for data backup
Bernas, Karel ; Pour, Jan (advisor) ; Pavlíčková, Jarmila (referee)
Thesis focuses on data deduplication, mainly in medium-term advances, using commercial solutions. Principles used in disk arrays deduplication are not part of this document. The thesis specifically shows a brief introduction to deduplication, which serves as an example of why it was necessary to come up with an improved solution. This solution is sparse indexing method, which was created in the laboratories of Hewlett Packard Ltd. This method is discussed in more detail and shown in which solutions specifically can be found. Following the analysis of sparse indexing method is the evaluation of a particular solution of backup and deduplication from HP in comparison with a solution that offers some of its competitors. At the end, there is the evaluation and commentary of the results, together with the general recommendations and best practices from a real, large-scale, data structures. These recommendations are put as specifications for particular operational tasks associated with deduplication approaches and procedures.
