Evaluation of federated database for distributed applications in e-government

Abstract

The evolution of the distributed database technologies represents a great opportunity in each sector of public administration to improve the efficiency of e-government, since the distributed technologies improve one of the basic need of the Public Administration, that is the interoperability between their different units, that is strictly related to the ability of retrieving data located on different archives. As known, the federated database approach could represent a solution to data integration, but the existing solutions often don't take into account real time constraints that are more and more required by the modern e-government scenario. For this reason, in this paper a performance evaluation of relevant technologies implementing the federated database solution is done and compared with the performance of a software architecture consisting of a cloud of web services we have developed to support data integration for the administrative units of a municipal administration. The results confirm the low time performance of the federated data solutions when the integration deals with a large amount of data, whereas the proposed customizable solution shows appreciable high performance.

Research Trends in E-Government Interoperability: Mapping Themes and Concepts Based on The Scopus Database

“…For example, in this case, the work of Pardo T.A., Nam T., Burke G.B., (2012) with the title E-Government Interoperability: Interaction of Policy, Management, and Technology Dimensions, and Bannister & Connolly, (2013) with the title Forward to the Past: Lessons for the future of e-government from the story so far, these two articles are interpreted as two subject areas, namely entering the themes of Computer Science and Social Science, as well as several other of research. (Kirstein et al, 2019;Lips et al, 2020;Ansgar Mondorf & Wimmer, 2016), as well as an evaluation of the running of an e-government program in Europe (Pino et al, 2013;Rantos, 2011), and in this case study e-government interoperability is one of the themes discussed (Bovalis et al, 2014).…”
