Retrieval-Augmented Intelligent Data Warehousing for Decision Support Systems
Organizations are increasingly challenged by massive volumes of structured, semi-structured, and unstructured data generated from enterprise systems, cloud platforms, IoT devices, social media, and industrial applications. Traditional data warehouses are effective for historical analytics but lack the ability to provide semantic understanding, dynamic knowledge retrieval, and real-time decision support. This study proposes a Retrieval-Augmented Intelligent Data Warehousing (RAIDW) framework that integrates Retrieval-Augmented Generation (RAG), vector databases, knowledge graphs, semantic search, machine learning, and large language models with conventional data warehousing. The framework combines ETL pipelines, vector indexing, retrieval ranking, and transformer-based reasoning to deliver context-aware, explainable, and accurate analytical insights. Machine learning improves retrieval relevance, while feedback mechanisms continuously enhance system performance. Experimental results demonstrate significant improvements in retrieval precision, analytical accuracy, semantic consistency, query efficiency, and decision confidence compared to traditional OLAP-based systems. The proposed architecture supports diverse domains, including healthcare, finance, supply chain, manufacturing, cybersecurity, and education, while ensuring governance, scalability, transparency, and security. By grounding AI-generated responses in trusted enterprise knowledge, the framework minimizes hallucinations and enables reliable, intelligent enterprise decision support.
Hybrid AI and Digital Twin Architecture for Enterprise Commerce and Financial Transformation
Enterprise commerce and financial ecosystems are being transformed by Artificial Intelligence (AI), Cloud Computing, Big Data, Blockchain, the Internet of Things (IoT), and intelligent automation. However, conventional enterprise information systems primarily support operational automation and often lack real-time predictive intelligence, adaptive decision-making, and integrated visibility across business processes. These limitations lead to data silos, inaccurate forecasting, operational inefficiencies, financial risks, and reduced organizational agility. This paper proposes a Hybrid AI and Digital Twin Architecture for Enterprise Commerce and Financial Transformation that integrates intelligent data acquisition, digital twin modeling, hybrid AI analytics, financial intelligence, enterprise optimization, and continuous learning into a unified computational framework. The architecture combines machine learning, deep learning, reinforcement learning, knowledge graphs, explainable AI, and optimization techniques with dynamic digital twins that continuously synchronize with data from ERP, CRM, IoT devices, cloud platforms, and financial systems. The proposed framework enables predictive analytics, business process simulation, anomaly detection, financial forecasting, automated risk assessment, and explainable decision support. Organizations can evaluate multiple operational scenarios within a virtual environment before implementation, thereby reducing uncertainty, improving resilience, and enhancing strategic planning. Mathematical models are also introduced to evaluate enterprise operational efficiency, digital twin synchronization, predictive intelligence, and financial transformation performance. The proposed architecture is expected to improve forecasting accuracy, optimize supply chain operations, strengthen fraud detection, reduce operational costs, enhance customer experience, support regulatory compliance, and promote sustainable enterprise growth. By integrating Hybrid AI with Digital Twin technology, the framework provides a scalable and intelligent foundation for autonomous commerce, resilient financial management, and data-driven enterprise transformation across diverse industrial sectors.

The study concludes that intelligent rule-based systems offer a scalable and efficient solution for modern data transformation in big data and real-time environments.
Adaptive Query Routing for High-Speed Distributed Data Systems
Adaptive query routing is essential in high-speed distributed data systems because static routing cannot effectively handle dynamic changes in network conditions, workloads, and system heterogeneity; instead, it dynamically selects optimal nodes or paths based on real-time factors such as latency, node availability, workload distribution, and past query performance, thereby improving efficiency, scalability, and reliability. Unlike early deterministic or heuristic methods, adaptive approaches use feedback mechanisms and probabilistic models to continuously update routing decisions, enhancing throughput and reducing query response time. The main strategies include centralized routing (with a global view but limited scalability and single-point failure risk), decentralized routing (better scalability but coordination challenges), and hybrid models (balancing both approaches). Additionally, techniques like caching, replication, and indexing help reduce unnecessary data transfer and improve execution speed, while mathematical cost models guide optimal routing decisions. Experimental results show that adaptive routing can improve query response time by 40–60% under dynamic workloads, making it a crucial component for modern distributed systems, especially in cloud computing and big data environments.

To overcome these challenges, semantic approaches based on ontologies, knowledge representation, and reasoning have gained importance. This work focuses on ontology-based integration, schema alignment, and semantic mediation to enable interoperability. It also examines integration models such as Global-as-View (GAV), Local-as-View (LAV), and hybrid approaches, along with semantic web technologies like RDF, OWL, and SPARQL. A systematic integration methodology is proposed, involving preprocessing, semantic annotation, ontology matching, conflict resolution, and query transformation. Mathematical models are used to define similarity measures and mapping confidence. Experimental evaluation on benchmark datasets shows improved accuracy, precision, recall, data consistency, and query efficiency compared to traditional methods. Despite these advancements, challenges such as scalability, ontology development, and semantic ambiguity remain open research issues.
