Abstract:

This article describes and investigates the difference between a decentralized and a centralized information system. The efficiency of use and introduction of new technologies in production is studied. The construction of blockchain-based systems and their efficiency in solving the tasks are analyzed. Conclusions are formed about the tendency that the introduction of decentralization proves the need for digital management systems. At a time when the implementation of blockchain technology has greatly simplified the construction of new decentralized systems, which is a current trend in the worl

Abstract:

This paper presents an algorithm for two-phase locking (2PL) in which deadlocks of distributed transactions for distributed database management systems (DDBMS) are avoided. The method of timestamps is chosen for solving deadlocks and the centralized 2PL algorithm is implemented in DDBMS. The „wait - die” strategy of timestamps mechanism for deadlocks avoiding is presented in this paper. The simulation results of modeling “wait-die” algorithm are given by using GPSS World Personal Version for two and three elements length of distributed transaction.

However, current IoT-based logistics systems face significant challenges, including complex data management, limited interoperability among stakeholders, and inefficiencies resulting from centralized control mechanisms. Blockchain technology has emerged as a promising solution to address these critical issues within logistics and supply chain management. This paper presents a comparative analys

Abstract:

<p>Congestion management (CM) in the deregulated power systems is germane and of central importance to the power industry. In this paper, an optimal power flow (OPF) based CM approach is proposed whose objective is to minimize the absolute MW of rescheduling. The proposed optimization problem is solved with the objectives of total generation cost minimization and the total congestion cost minimization. In the centralized market clearing model, the sellers (i.e., the competitive generators) submit their incremental and decremental bid prices in a real-time balancing market. These can then

Abstract:

Client-server-based healthcare systems are unable to manipulate a high data volume, prone to a single failure point, limited scalability, and data integrity. Particularly, several measures introduced to help curb the spread of Covid-19 were not effective and patient records were not adequately managed and maintained. Most vaccination-proof certificates were forged by unauthorized parties and no standard verification medium exists. Therefore, this paper proposes a blockchain-enabled vaccination management system (VMS). VMS utilizes smart contracts to store encrypted patients record, generate va

Abstract:

Omnichannel is not just a marketing, e-commerce, or customer support buzzword. This future customer engagement platform helps businesses communicate with customers through centralized channels on a smart interface. It is difficult to achieve customer loyalty when the risk in online transactions, which creates anxiety, exists in all transaction processes in an omnichannel system. Hence, the purpose of this research was to analyze the influence of anxiety on relationships when clients purchase from an omnichannel platform using the stimulus–organism–response (SOR) paradigm.

Abstract:

As financial institutions increasingly migrate their core platforms to microservices-based architectures, the challenge of managing distributed transactions has gained critical importance. Banking APIs typically require atomicity and consistency across multiple services—such as account management, fraud detection, notifications, and audit trails all of which operate independently with isolated data stores. In such an ecosystem, ensuring consistency, performance, and fault tolerance becomes a balancing act that traditional and modern transaction patterns attempt to resolve differently. This pap

Abstract:

Organ donation and transplantation (ODaT) are essential elements of modern healthcare. However, the systems that oversee these processes often face significant challenges, such as inefficiency, security vulnerabilities and the prospect of unethical practices like organ trafficking. The traditional centralized systems often break down while maintaining data integrity, transparency, and equitable distribution of organs. In this paper, we propose an approach that integrates the AES encryption with a blockchain platform known as Corda in order to preserve privacy for a robust and secure transactio

The majority of the existing land information systems (LIS) are centralized, transaction processing systems based on object-relational database management systems for data storage, management, and retrieval. These traditional database management systems are dominantly based on a share-everything or share disk architecture and face challenges in meeting the performance and scalability requirements of distributed, data-intensive systems, including LIS. They support vertical, rather than horizontal scalability, which is of particular importance in distributed systems. In some cases, due to legal,

Abstract:

Distributed ledgers (DLs) provide many advantages over centralized solutions in Internet of Things projects, including but not limited to improved security, transparency, and fault tolerance. To leverage DLs at scale, their well-known limitation (i.e., performance) should be adequately analyzed and addressed. Directed acyclic graph-based DLs have been proposed to tackle the performance and scalability issues by design. The first among them, IOTA, has shown promising signs in addressing the preceding issues. IOTA is an open source DL designed for the Internet of Things. It uses a directed acycl
