Extending Data Lineage Analysis Platform with Support for Dependency Injection Frameworks
Riedel, Lukáš ; Parízek, Pavel (advisor) ; Hnětynka, Petr (referee)
Data lineage forms an important aspect of today's enterprise environment. MANTA Flow is a data lineage analysis platform that already has basic support for analysis of Java programs, provided by one of its components called Bytecode Scanner. Neverthe- less, there are very few applications in today's enterprise environment that do not use dependency injection at least in a very limited way. Therefore, we present an extension of Bytecode Scanner in the MANTA Flow platform to support data lineage analysis of dependency injection frameworks as well. The extension is able to process even complex definitions of standard dependency injection containers. Since the dependency injec- tion influences a selection of method call targets, we also provide a description of call graph structure and its modification to support dependency injection. Last, we use this infrastructure to design and implement a plugin into Bytecode Scanner for the Spring Framework, a popular dependency injection framework targeting Java Platform. The plugin has been successfully tested on a small but realistic software system that can read data from a file, transform them, and write them into a database. 1

Public Transport Timetables
Riedel, Lukáš ; Zavoral, Filip (advisor) ; Holan, Tomáš (referee)
It is in the interest of people using public transport to get to the desired location as quickly as possible. That is the reason they use search engines to search journeys. Most existing search engines are limited to a predetermined area or can only be used with a permanent internet connection, which may limit the user. For this reason, we have designed a customizable application system that allows the user, under certain conditions, to search without the need for an Internet connection. In the thesis we analyse mainly with the ways of finding journeys in timetables. Our solution uses an innovative algorithm that, with its operation and time required to execute a request, deviates significantly from most existing solutions. For the convenience of the user, we have developed a desktop and mobile application that provides the user user-friendly interface that can be used to search timetables and display current traffic information. 1
