A model for the evaluation of risks and control features in ORACLE 708 September 2015 (has links)
M.Com. / The proliferation of computers and the advances in technology introduced a number of new and additional management and control considerations. The inherent complexity of these environments has also increased the need to evaluate the adequacy of controls from an audit perspective. Due to the increasing use of database management systems as the backbone of information processing applications and the inherent complexities and diversity of these environments, the auditor is faced with the challenge of whether and to what extent reliance may be placed on the data contained in these databases...

Optimalizace ETL procesů / ETL process optimizationŽák, Vítězslav January 2010 (has links)
At a certain point of its life cycle, each data warehouse gets into a state in which the length of the ETL processing starts slowly approaching the acceptable limit. Even the slightest lapse means a hardly erasable time lag and the data supplies to users are increasingly delayed. Before the situation becomes more problematic, we need to react. This diploma thesis deals with the possible solutions of this problem- the ETL performance optimization. The main aim of the thesis is to propose the set of recommendations for the ETL process optimization and its presentation based on practical real world examples. While going through this thesis, the readers get inside the running of the real ETL optimization project. They learn how to proceed during its particular periods, what to avoid and how to reduce the risk level as much as possible. Moreover, the thesis mentions the prevention of the ETL performance loss and discusses the critical factors of the effective ETL process design. Although the proposed methods are described in a general perspective, the thesis is mainly focused on Oracle's database, which is its certain limitation. Also hardware optimization is not a part of the text. First chapters of the thesis describe the problem from the theoretical point of view, which is important for the correct understanding of the main content and the existing literature concerning this problematic is included here as well. Next sections describe the proposed methods and recommendations for the optimization of the ETL processes including tests and project results evaluation. They are mainly focused on the ETL process synchronization and the SQL code optimization areas. All the methods are presented of examples of the real project implemented by the author.

Srovnání robustních a open source databázových systémů / Comparison of robust and open source database management systemsVích, Marek January 2007 (has links)
Práce se zabývá problematikou objektově-relačních databázových systémů. Cílem je analýza současné situace na poli databázových platforem ze sféry tradičních robustních i open source produktů, která by vedla k posouzení předpokladů uplatnění otevřených databázových platforem v oblastech dosud charakteristických především pro tradiční distributory. Na počátku práce nejprve přibližuji čtenáři otázky související s distribucí softwaru (proprietární vs. open source) a základní pojmy v oboru databázových systémů. Po tomto výchozím uvedení stanovuji kriteria pro následnou komparaci vybraných databázových platforem, která předurčují další postup v rozhodující části věnované komparační analýze. K dovršení celého rozboru práci uzavírám nastíněním přítomných možností využití tradičních robustních a především pak open source databázových systémů. Komparační analýza je vystavena na základě předem definovaných kritérií do pěti oddílů zohledňujících základní charakteristiky, technologické a funkční vlastnosti, bezpečnost, dostupnost i podporu produktů a nevěnuje se rozboru z hlediska výkonu a optimalizace. Za účelem srovnání byly vybrány čtyři přední databázové systémy ? Oracle, DB2, Teradata a PostgreSQL. V návaznosti na důkladnou analýzu, která vedla ke zmapování aktuální situace na databázovém trhu, jsou v závěru práce vytknuty hlavní faktory kolidující širšímu uplatnění open source platforem.
