From Data Complexity to Decision Intelligence: Modeling and Quality Challenges in SAP Environments
Reneta Duhova
 

Abstract: Organizations operating within modern SAP (Systems, Applications and Products in Data Processing) landscapes are increasingly confronted with a range of complex challenges arising from the diverse and fragmented nature of enterprise data. This data originates from a variety of sources, including transactional systems, legacy databases and unstructured formats. The diversity of these sources creates major challenges in integration, scalability, data quality and regulatory compliance. Addressing these issues is essential to enable effective and sustainable decision-making processes. This work explores current advancements in SAP technologies, such as SAP Datasphere, SAP S/4 HANA and the SAP Business Technology Platform (BTP), which offer powerful capabilities for semantic integration, real-time analytics and enhanced automation. Following a review of recent studies and official SAP innovations, the analysis highlights the importance of continuous data quality management and modular governance structures. It also emphasizes the growing role of artificial intelligence (AI) and machine learning (ML) within decision intelligence frameworks.

Keywords: data complexity, decision intelligence, SAP Datasphere, data modeling, proactive governance

Embedded System for Monitoring and Watering Indoor Plants with Web Interface Using ESP32
Kamelia Raynova, Veselin Gospodinov
 

Abstract: This paper presents the design and implementation of an embedded system for automated monitoring and irrigation of indoor plants, using ESP32 microcontroller. The system integrates soil moisture sensor, temperature sensor, and air humidity sensor. The collected data is processed in real time and made accessible through web-based interface, allowing users to remotely monitor via Wi-Fi. The proposed system aims to enhance plant care for individuals with limited time or experience.

Keywords: automated, ESP32, sensor, web, Wi-Fi
