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.

Requirements analysis and design of registration IS - case study
Adámek, Vlastimil ; Oškrdal, Václav (advisor) ; Veber, Jaromír (referee)
The main goal of this thesis is to create a catalog of requirements for registration information system for a large security company. The thesis is compile as a guide for the selection of possible solutions to the problem arising from the absence of information registration system and the transition to record data in electronic form also known as a paperless concept. The secondary objective is to introduce best practices for requirements management. The theoretical part consists of six main chapters. First introduces the basic concepts. As I consider the most important part of the next chapter dealing with the demands, with an emphasis on the importance of requirements. At the same time in this chapter will try to fulfill the secondary goal. Easily describe the role of project manager and an analysis based on the findings of the current situation of enterprises in the Czech Republic regarding IT. The final part of the theoretical part is based on the performance of the most basic methods of data collection requirements. The practical part is based on information from the theoretical part, knowledge of the educated subjects and experience of working as security guard. It is carefully selected and suitable method for gathering requirements, and this choice is explained in detail. After analyzing the requirements is made requirements catalog, which is the output of the whole work. Constructing a catalog of requirements is thus completed the first phase of project planning, and to collect and analyze requirements. Output of the thesis can be used for the second phase and system development.

Requirements analysis and design of IS - case study
Plechatý, Radek ; Oškrdal, Václav (advisor) ; Pavlíček, Antonín (referee)
The aim of the thesis is to acquaint the readers with the concept of acquiring requirements for the information system design. The theoretical part of the thesis defines what a requirement is, what different types of requirements there are, the structure of the requirement catalogue and the role of an analyst while acquiring user requirements. The theoretical part then describes methods used to acquire and record requirements. The practical part applies the discussed topics to real life organization. The two most effective methods for acquiring and recording requirements are selected for this organization. The organization undergoes a requirement analysis with the use of these methods. Requirement catalogue is created based on this analysis. The catalogue will assist in designing a new information system for the organization.

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.
