Item type:Publication, Databases fit for blockchain technology: A complete overview(Elsevier, 2023-03-01); Gligoroski, DaniloEfficient data storage and query processing systems play a vital role in many different research areas. Blockchain technology and distributed ledgers attract massive attention and trigger multiple projects in various industries. Nevertheless, blockchain still lacks the features of a Database Management System (DBMS or simply databases), such as high throughput, low latency, and high capacity. For that purpose, there have been many proposed approaches for handling data storage and query processing solutions in the blockchain. This paper presents a complete overview of many different DBMS types and how these systems can be used to implement, enhance, and further improve blockchain technology. More concretely, we give an overview of 10 transactional, an extensive overview of 14 analytical, 9 hybrids, i.e., translytical, and 13 blockchain DBMSs. We explain how database technology has influenced the development of blockchain technology by unlocking different features, such as Atomicity, Consistency, Isolation, and Durability (ACID), transaction consistency, rich queries, real-time analysis, and low latency. Using a relaxation approach analogous to the one used to prove the Consistency, Availability, Partition tolerance (CAP)-theorem, we postulate a “Decentralization, Consistency, and Scalability (DCS)-satisfiability conjecture” and give concrete strategies for achieving the relaxed DCS conditions. We also provide an overview of the different DBMSs, emphasizing their architecture, storage manager, query processing, and implementation. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, A narrative review of e-health systems' evolution – evidence from a regional study(Emerald Publishing Limited, 2024-05-29); ; ; Chagoroska, ZaklinaPurpose The growing implementation of electronic health (e-health) systems has raised the importance of analyzing how these systems have been implemented in diverse regions. By employing a contextual sensitive approach and social mechanism theory, this study aims to better understand the reasons for the success and failure of e-health initiatives in the ex-Yugoslav region and derive useful insights for policymakers. Design/methodology/approach We employ a narrative review process grounded in the social mechanism theory, extended with field experts’ review, to acquire state-of-the-art information. Findings Findings indicate that different e-health systems coexist and evolve in different contexts in different countries, with varying levels of success. The contextual differences shape the broader environment, affecting the level of preparedness and capability for e-health implementation. Top-down approaches dominate e-health implementation in most countries when it comes to design process features, and more developed countries do not rely on strong social mechanisms for implementing e-health due to the openness of their culture towards e-health innovations. Practical implications Analyzing the milestones, challenges and functionalities of e-health systems in the region of interest can assist policymakers, academics and practitioners in making informed decisions and recommendations to enhance future e-health implementation. Originality/value No known studies evaluated e-health initiatives in the former ex-Yugoslav countries holistically and evolutionarily in the form of a comprehensive regional study. Further, our research endeavor is contextually specific since the health systems of these countries in the past were tied together under the federative umbrella health system and then diverged in terms of e-health development. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Dynamic Evolution and Improvement of Data Warehouse Design(IEEE, 2009); ; Frequently changing business requirements result not only in changesto the data warehouse (DW) workload but also in changes to the schemastructure. These schema changes introduce new DW versions and so theproblem of optimization of all of its versions becomes a very challengingone.In this paper we present a new approach for dynamically evolving thedesign of the implementation schema spanning across its multiple versions.A new derivation procedure for self improvement of the design andthe performance of the model is applied in several steps. We alsodefine a system for optimization of the design of the multiversionDW schema and its particular instances and include other factors relevantfor optimization of the system i.e. view selection, vertical viewfragmentation and index selection. The self improvement of the multiversionschema design is shown by performing large set of experiments. - Some of the metrics are blocked by yourconsent settings
