Design of methodology for BI solutions testing
Jakubičková, Nela ; Pour, Jan (advisor) ; Zajíc, Ján (referee)
This thesis deals with Business Intelligence and its testing. It seeks to highlight the differences from the classical software testing and finally design a methodology for BI solutions testing that could be used in practice on real projects of BI companies. The aim of thesis is to design a methodology for BI solutions testing based on theoretical knowledge of Business Intelligence and software testing with an emphasis on the specific BI characteristics and requirements and also in accordance with Clever Decision's requirements and test it in practice on a real project in this company. The paper is written up on the basis of studying literature in the field of Business Intelligence and software testing from Czech and foreign sources as well as on the recommendations and experience of Clever Decision's employees. It is one of the few if not the first sources dealing with methodology for BI solutions testing in the Czech language. This work could also serve as a basis for more comprehensive methodologies of BI solutions testing. The thesis can be divided into theoretical and practical part. The theoretical part tries to explain the purpose of Business Intelligence use in enterprises. It elucidates particular components of the BI solution, then the actual software testing, various types of tests, with emphasis on the differences and specificities of Business Intelligence. The theoretical part is followed by designed methodology for BI solutions using a generic model for the BI/DW solution testing. The practical part's highlight is the description of real BI project testing in Clever Decision according to the designed methodology.

Methodology for solution of transformation part of BI (ETL)
Cimbaľák, Michal ; Pour, Jan (advisor) ; Zajíc, Ján (referee)
Extract, Transformation, and Load (ETL) system is responsible for the extraction of data from several sources, their cleansing, conforming and insertion into a data warehouse. The thesis is focused on building ETL methodology to better understanding of ETL process and its application in the real environment. I've worked on project "BI Cookbook" with Clever Decision, a software consulting company that specializes in Business Intelligence. The aim was to create ETL part of the BI methodology. This methodology has been designed to provide ease of use, flexible and extensible material for the purpose of building ETL solution. The main goal of this work is to introduce created ETL methodology, all of its components and the way in which it could be used. Following goal is to discuss options of its implementation and modification for the wide range of use. The main contribution of this work is to provide ideas of creating and implementing ETL methodology or ideas for creating methodology in general. The thesis is divided into three parts. The first theoretical part deals with basic definition, architecture and implementing of ETL system. The second part presents the proposed methodology. The last part contains of the possible options for implementation a modification of the methodology.
