Stejskal, Jan ; Chlapek, Dušan (advisor) ; Bruckner, Tomáš (referee)
This work deals with the use of NoSQL database systems in an environment of financial institutions. The work has several objectives: to characterize the types of NoSQL database systems, for selected systems to analyze their properties, their potential use in financial institutions to develop proposals case studies for their use, and one of them select and implement a demonstration of the possibilities of using this type of database system in the specific environment of financial institutions. These objectives are to be achieved by providing a description and analysis of the theoretical part, practical part in designing, choosing, implementation, verification and acceptance of one case study - based on acceptances criteria. In the thesis are the basic concepts of database systems explained first. It is explained in more detail the concept of NoSQL and related terms including causes and genesis, classification systems NoSQL in each category. The next part contains a comparison of the characteristics of relational database - relational systems and NoSQL database systems. The next chapter deals with the needs of financial institutions in the context of the use of database systems. There are also analyzed the properties of several selected NoSQL database systems . The next chapter is based on the analytical findings from previous chapters devoted to finding poten-tials lu use NoSQL database systems in an environment of financial institutions, which is the basic theme of the thesis . The penultimate chapter contains a suggestions of case studies, one of which is selected and a description of the results of its implementation are described in the last chapter . The main contribution of this work is a contribution to the theory of NoSQL systems and the possibili-ty of their use by financial institutions, which take into account when choosing a database system, or a combination of database systems, in practical terms can lead not only to increase the efficiency of their use, but also to optimize the acquisition and operational the costs of such systems.
