Vyhodnocování relačních dotazů v proudově orientovaném prostředí
Kikta, Marcel ; Bednárek, David (advisor) ; Černý, Tomáš (referee)
This thesis deals with the design and implementation of an optimizer and a transformer of relational queries. Firstly, the thesis describes the theory of the relational query compilers. Secondly, we present the data structures and algorithms used in the implemented tool. Finally, the important implementation details of the developed tool are discussed. Part of the thesis is the selection of used relational algebra operators and design of an appropriate input. Input of the implemented software is a query written in a XML file in the form of relational algebra. Query is optimized and transformed into physical plan which will be executed in the parallelization framework Bobox. Developed compiler outputs physical plan written in the Bobolang language, which serves as an input for the Bobox. Powered by TCPDF (
Geometric algorithm visualization
Kikta, Marcel ; Pergel, Martin (advisor) ; Surynek, Pavel (referee)
This thesis deals with designing programming language, compiler and~intepreter assigned for visualization of geometric algorithms. Emphasis is put on designing the simplest language and on quality of visualization environment. During compiler implementation a syntactic LL(1) parser generator was created. As a demonstration of functionality thesis contains implementation of some geometric algorithms written in designed language.
