Relational and NoSQL database for collecting data from IoT devices
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.

Smart Home - library for data acquisition
Tomiczek, Roman ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
The diploma thesis deals with the development of a software library for aggregating data from electricity meters and sending data to a central station. The most used protocols in smart grids are described. The work deals in more detail with the most important parts of the DLMS/COSEM standard. The DLMS protocol is described, which ensures communication between clients and servers. Next, the COSEM object model is described, which specifies object modeling, for access to measuring devices, and the OBIS system, which determines the identification of data objects. The Gurux library, which specializes in intelligent meter readings, is also described. The results of the work describe the implementation and testing of a software library for aggregation of data from servers using the DLMS/COSEM protocol using the GURUX library. At the end of the work is described a series of tests that were performed using this software library.
