Tomiczek, Roman ; Štůsek, Martin (referee) ; Šeda, Pavel (advisor)
This bachelor work is focused on the analysis of the relational and NoSQL (Not only SQL) databases for collecting a huge amount of data from IoT (Internet of Things) device. Theoretical part contains an introduction to the problematic of the relational and NoSQL databases. The relational database describes fundamental principles, relational algebra, normal forms and so on. The non-relational database characterises the main properties and describes different types of typologies. It deals with the NoSQL documentation databases called Elasticsearch as well. Practical part contains a proposal and realization of the MySQL database, realization non-relational database Elasticsearch as well as JavaFx application for measurement of database parameters. Further contains results of the measurement of parameters and properties of databases.

Search as a Service
Veselý, Luděk ; Molnár, Zdeněk (advisor) ; Jelínek, Ivan (referee)
This thesis is focused on design and implementation of fulltext searching, which is provided as a servise. The searching itself is focused on the utilization in e-shops. At the beginning, the question of e-commerce is analysed, the related terms are explained and the requirements of searching are identified. Then, the theoretical ways of text searching in this context are described. On the analyse is created a conception of application, which is further implemented in the language Go with the usage of Elasticresearch. Finally, the application is tested, which should examine not only the quality and speed of searching but also the user-friendliness.

Automatically Updated Web Portal
Staněk, Petr ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)
This bachelor's thesis is dedicated to the design and implementation of an automatically updated web portal that tries to resolve the shortcomings of the portals filled with other people's content. Furthermore, it presents a comparison of the existing scientific portals, it discusses the problems of extraction, saving and searching for information. General mechanisms are demonstrated on the European research projects portal, which removes the shortcomings of CORDIS, the official information portal for European research and development. The thesis takes the existing product as a prototype and its aim is to improve the quality of the extraction and extend the system to detect any potential problems and notified an administrator of them. This was achieved by increasing the robustness and speed of the extractor, by registering all the important events associated with the extraction and, on the other side, the implementation of the separate administrator section of the web portal, which informs the administrator about problems and offers the problem-solving devices.
