Proposal and application of model for testing DWH implementation on Teradata platform
Lysáček, Jakub ; Matuštík, Ondřej (advisor) ; Meixner, Jiří (referee)
The thesis focuses on application of theory of software testing in data warehousing area. The main goal of the thesis is an introduction of selected theory of software testing and analogical use of the theory in data warehousing environment. Part of the main goal is an introduction of architectonic model of testing process and later on focusing on part of testing which is problematic in data warehousing area. Partial goal of the thesis is validation of problematic part of the model using practical scenario. This partial goal is divided into two parts. First part focuses on requirements gathering and categorizing their priority. Second part focuses on demonstrating how project requirements, available resources and Teradata specific environment manipulate with the testing process. Theoretical part summarizes selected theory of software testing which is later applied in the area of data warehouse testing. The chapter introduces phases of data warehouse testing and specific goals of each testing phase. Chapter also describes model FURPS which is used to classify software quality dimensions a selected methods of requirements priority classification. An architectural model of testing process and its entities are described in the second part of theory. The theory then focuses on problematic part of the model which is requirements gathering and classification of their priority and demonstrates the influence of time, quality requirements and available resources on the overall process of testing. Practical part introduces a real-life scenario which demonstrates an application of described theory, namely requirements gathering, classification of requirements priorities and assigning dimensions of quality. The next part demonstrates the influence of available resources and requirements on the scope of testing. The outcome of the practical part of the thesis is that requirements gathering and classification of their priorities allows us to classify and sort scope of testing into logical and clear units, assign roles and their responsibilities and flexibly react on changes of project requirements. The thesis also points out that there are risks associated with changes of scope and emphasizes on the need of their evaluation.

Analysis of software requirements in the environment of bank instituiton
Theier, Radek ; Bruckner, Tomáš (advisor) ; Benešovský, Miroslav (referee)
This diploma thesis deals with the requirements engineering as one of the key areas of development of software applications. By requirements prospective users express their needs and goals which shall be achieved using the developed application. The correctness and completeness of the requirements is thus critical for the success of any software project. The main objective of this dissertation is determination of steps which must be made to improve quality of requirements on real software project in Czech financial institution. This is achieved by analysis of current requirements development process as well as by analysis of the sample of specific requirements. One part of the carried out analysis focuses also on the revision of actual settings of Atlassian JIRA application which is used for requirements management. Based on the analysis some crucial shortcomings are identified and steps for their elimination are introduced. This includes, inter alia, manual of how to specify correct requirements and checklists for different actors who work with requirements. The theoretical part gives a comprehensive overview of selected techniques and practices which are applicable for requirements gathering and analysis. Every mentioned technique is then evaluated from the perspective of its usability in the environment of large Czech bank. This overview can be useful both for junior analytics as a collection of best practices and for senior analytics as an overview of possible areas for their professional development.

Methods of requirements gathering
Micka, Radek ; Kunstová, Renáta (advisor) ; Meloun, Michal (referee)
The aim of this work is to provide comprehensive information about the process of gathering information system requirements and the practical use of obtained informations on a real project. The paper defines the notion of requirement. It further describes the various methods of collecting and recording requirements. In a separate chapter are described phases of requirement process. The practical case demonstrates using of acquired methods and knowledge. The outputs of this work are written requirements for information system and a prototype, which was one of the tools for requirements gathering.
