Datamining - teorie a praxe
 Popelka, Aleš ; Maryška, Miloš (advisor) ; Machač, Ivo (referee)
This thesis deals with the topic of the technology called data mining. First, the thesis describes the term data mining as an independent discipline and then its processing methods and the most common use. The term data mining is thereafter explained with the help of methodologies describing all parts of the process of knowledge discovery in databases -- CRISP-DM, SEMMA. The study's purpose is presenting new data mining methods and particular algorithms -- decision trees, neural networks and genetic algorithms. These facts are used as theoretical introduction, which is followed by practical application searching for causes of meningoencephalitis development of certain sample of patients. Decision trees in system Clementine, which is one of the top datamining tools, were used for the analysys.

Object-relational mapping on .NET
 Popelka, Aleš ; Pavlíčková, Jarmila (advisor) ; Machač, Ivo (referee)
This study concerns the theme of object-relational mapping on the .NET platform. It briefly explains the differences in the relational and object view on data a therefore it describes design patterns which are in object-relational mapping vastly applied. These design patterns are described in order to inform the reader about their advantages as also disadvantages and they are commonly depicted with an elementary illustration. The description of the design patterns is followed with a specification of the .NET framework and other elements (e.g Visual Studio 2008), which are essential to define for further progress in this study. The specification concludes into description of four products, which serve as modelers and generators of the object-relational mapping layer. The goal of this study is to provide a view of the object-relational impedance mismatch issue, means of its solution to the reader and help him with eventual need to invest into products which aid in object-relational mapping on .NET. For potential need to invest in other products than those which are tested in this study is the reader supplied with well-formed rating criteria which are, in my opinion, ready for being standardised. These goals are achieved by generating the mapping layer with all four tested products and description of the mapping process and the layer afterwards.
