Administrative data propagation in an information system
Vostatek, Filip ; Buchalcevová, Alena (advisor) ; Borguľa, Martin (referee)
The goal of this paper is to demonstrate a technologically superior solution of data propagation from an administration interface of an information system and formulate it as a design/solution pattern. That corresponds with the basic form of the text, where the design pattern is defined in 13 subchapters in a structure commonly used to define design patterns. The solution is introduced as a design pattern because of high reusability and because of the problem it challenges being so frequent in modern information systems -- that is also where the benefit of this paper lies.

Jersák, Pavel ; Smolík, Jan (advisor) ; Kyjonka, Vladimír (referee)
The main issue of this work is Common Warehouse Metamodel (CWM) which is used both as the standard for metadata in data warehousing and business intelligence and as means of exchange of metadata between tools in DWH. As this issue of CWM and metadata management has not been published in Czech-language so far, the main aim of this work is to introduce Common Warehouse Metamodel, its utilization in BI and also to present advantages of metadata management implementation based on CWM.

Data backup and archivation
Hrubeš, Jan ; Jandoš, Jaroslav (advisor) ; Čech, Milan (referee)
With increasing amount of data, standards for storing and security became more important theme. Potential losing of data may be irretrievable loss for a given subject and may cause disaster. From that reason, there is an aim of the work, to offer brief summary of nowadays possibilities of data securing and backuping in a company or at home conditions. Work is focused on data description and clasification, as a base security required object. Following parts of my work describe view of available technologies (Harware and Software) and generalized process of choosing suitable technology, applicable for particular system. Benefit of my work consists in systematic summary of present data backuping and archiving and in creating general method for choosing the right technologi for backup.

Master Data Management
Jakoubek, Jiří ; Pour, Jan (advisor) ; Zajíc, Ján (referee)
Master Data Management (MDM) represents relatively newly emerging domain. The main objective of the MDM program is to provide policies, procedures, and infrastructures that support organization, exploitation and distribution of the enterprise master data. The work is divided into two elemental parts. Goal of the first part is to answer the principal questions related to the MDM. It deals with reasons of the origin of MDM and with explanation of master data and master data management. It determines the relations between MDM and other enterprise information systems (ERP, SCM, CRM etc.), describes contributions that can bring the implementation of MDM into the enterprise and shows some indicators of the data quality in the way of MDM. There is also specified who is interested in the implementation of MDM into the enterprise and who participates in this implementation. The end of the first theoretical part shows and describes MDM component and service model. The objective of the second, practical part is to project a technique of the administration of master data in practice. It describes technologies that help in achieving this goal and it also shows an example on the representative table of master data. This part is based on the practical experience on real project that was made in cooperation with CleverDecision, s.r.o.

The analysis of BI tools in Oracle's environment
Nisznanský, Petr ; Pour, Jan (advisor) ; Derfler, Václav (referee)
Hlavním cílem diplomové práce (DP) je provedení analýzy prostředí a jednotlivých nástrojů na podporu Business Intelligence (BI) na platformě Oracle. Analýza zahrnuje komplexní proces BI řešení od instalace potřebných programových prostředků (databáze, BI balíky, dokumentace atd.) až po zprovoznění praktické demonstrační aplikace a zhodnocení celé platformy. Práce se skládá ze čtyřech hlavních částí. V první části uvádím čtenáře do problematiky BI. V druhé části analyzuji globální charakteristiky prostředí Oracle BI a porovnávám je s SQL Serverem. Třetí část obsahuje analýzu a komparaci systému Oracle BI se systémem SQL Server ve třech oblastech (oblasti zahrnují: extrakci ? transformaci ? natažení dat, analytické zpracování dat a reporting) včetně vyhodnocení uvedených oblastí podle několika kritérií. V jednotlivých oblastech zjišťuji zejména dílčí architektury, používané nástroje a jejich funkcionalitu. Poslední část doplňuje stručnou analýzu světového trhu OLAP technologií.

Metodika hodnocení finančních výkazů a návrh aplikace pro jejich zpracování
Nápravník, Lukáš ; Klas, Jan (advisor) ; Novotný, Jakub (referee)
Jedním ze způsobů, jak přiblížit lidem ekonomické a účetní pojmy, je populární forma spočívající v sestavení žebříčku firem. Tato bakalářská práce se zabývá popisem problematiky spojené s jeho tvorbou. Důraz je v práci kladen na problematiku návrhu aplikace, která bude data zpracovávat a vyhodnocovat. Tato problematika tvoří nejpodstatnější část dokumentu a zahrnuje témata volby vhodné metodiky návrhu, výběru technologií, za jejichž použití bude aplikace implementována, diskuzi možných variant přenosu dat mezi externím zdrojem dat a databází aplikace, a samotný návrh. Prioritně je přitom dbáno na jednoduchost procesu zpracování dat a nízkou náročnost ovládání pro uživatele. Úkol návrhu aplikace pro zpracování a vyhodnocení dat je v práci zasazen do širšího kontextu dalších částí, které projekt sestavování žebříčku zahrnuje.
