In this paper we present the research objectives and methodology for a running project of distributed web processing geo-services for spatio-temporal analysis of geo-data, the case of Lloyd’s lists. We introduce the current problems and discuss the solutions in means of theoretical and practical perspectives. Initial results from geo-data modeling using Unified Modeling Language (UML) is presen...

Data integration is frequently performed between heterogeneous data sources, requiring that not only the structure of the data, but also the data modelling language in which that structure is represented must be transformed between one data source and another data source. This paper describes an extension to the hypergraph data model (HDM), used in the AutoMed data integration approach, that al...

The article describes the IoT infrastructure, hardware of system, considers issue security chosen LoRa data transmission technology. Data was received from sensors for gas, temperature and humidity, atmospheric pressure, as well location end device. At same time, standardized features selected technology transmitting to server were investigated. deals with bi-directional secure communication li...

Software interoperability may be achieved by using their respective conceptual data models. However, each model may be represented in a different conceptual data modelling language for the tool’s purpose or due to legacy issues. Several translations between small subsets of language features are known, but no unified model exists that includes all their language features. Aiming toward filling ...

From the side of modelers and early-adopter industry, interest in reasoning over conceptual models and other online usage of conceptual models is growing. To obtain a more precise insight in the characteristics of the main conceptual modeling languages, we define the (semi-)standardized ORM, ORM2, UML, ER, and EER diagram languages in terms of the new generic conceptual data modeling language C...

Process discovery techniques have successfully been applied in a range of domains to automatically discover process models from event data. Unfortunately existing discovery techniques only discover a behavioral perspective of processes, where the data perspective is often as a second-class citizen. Besides, these discovery techniques fail to deal with object-centric data with manyto-many relati...

In this paper, we present a conceptual data model for multimedia database applications based on ExIFO2 model. The ExIFO2 data model is chosen as the conceptual model since it handles both complex objects along with their uncertain and imprecise properties. We enhanced this conceptual model in order to meet the multimedia data requirements. In addition to uncertain and imprecise information, we ...
