Analyzing Data Lineage in Database Frameworks
 Eliáš, Richard ; Parízek, Pavel (advisor) ; Hnětynka, Petr (referee)
Large information systems are typically implemented using frameworks and libraries. An important property of such systems is data lineage - the flow of data loaded from one system (e.g. database), through the program code, and back to another system. We implemented the Java Resolver tool for data lineage analysis of Java programs based on the Symbolic analysis library for computing data lineage of simple Java applications. The library supports only JDBC and I/O APIs to identify the sources and sinks of data flow. We proposed some archi- tecture changes to the library to make easily extensible by plugins that can add support for new data processing frameworks. We implemented such plugins for few frameworks with different approach for accessing the data, including Spring JDBC, MyBatis and Kafka. Our tests show that this approach works and can be usable in practice. 1

RNA secondary structure visualization using existing structures
 Eliáš, Richard ; Hoksza, David (advisor) ; Jelínek, Jan (referee)
Many research aim to RNA molecules and demand for tools enabling their analysis increased. First step is visual inspection of their secondary structure. In order to correctly lay out structure, the notion of optimal layout is required. However, this has never been formalized and is largely habitual. To tackle this problem we propose an algorithm capable of visualizing RNA structure using related one with known layout. Algorithm first converts both RNAs into a tree representation and using tree-edit-distance algorithm finds out the minimum number of operations to convert one structure into the other. All common motives are retained and the regions which differ are taken care of. Results show, that our algorithm is able to give good layouts even for relatively distant structures. It is well suited for visualization of homologous structures. Powered by TCPDF (www.tcpdf.org)
