Developing a government enterprise architecture framework to support the requirements of big and open linked data with the use of cloud computing

Abstract

Governmental and local authorities are facing many new information and communication technologies challenges. The amount of data is rapidly increasing. The data sets are published in different formats. New services are based on linking and processing differently structured data from various sources. Users expect openness of public data, fast processing, and intuitive visualisation. The article addresses the challenges and proposes a new government enterprise architecture framework. The following partial architectures are included: big and open linked data storage, processing, and publishing using cloud computing. At first, the key concepts are defined. Next, the basic architectural roles and components are specified. The components result from the decomposition of related frameworks. The main part of the article deals with the detailed proposal of the architecture framework and partial views on architecture (sub-architectures). A methodology, including a proposal of appropriate steps, solutions and responsibilities for them, is described in the next step -after the verification and validation of the new framework with respect to the attributes of quality. The new framework responds to emerging ICT trends in order to evolve government enterprise architecture continually and represent current architectural components and their relationships.

Extending reference architecture of big data systems towards machine learning in edge computing environments

“…Then, the identified elements were mapped into the high level architecture view of the RA [4] (see Figs. 6,7,8,9,10,11,12,13,14,15,16,17,18,19 and 20 for detailed mapping figures). Subsequently, the mapped implementation architectures of individual papers were merged into an updated RA, which included existing [4] and new elements ( Fig.…”

“…Also, RAs were systematically studied based on literature, and analysed in terms of architectural requirements, modules, layers, and patterns [5]. Additionally, RAs for big data systems have been developed by including security aspects [17], targeting plant genotyping and phenotyping systems [18], and government enterprise architecture frameworks [19].…”

Enterprise Architectures in E-Governments Studies: Why, What and How?

“…Some studies have been motivated to satisfy technical requirements. Such efforts are like an agile EA framework proposed to support government transformation with cloud technology enabled [21], an EA based approach to manage state-level data in real time in the Indian public sector of healthcare [22], a method to find patterns for enterprise information architecture in governments [23], a proposal for a framework for ICT governance [25], and a government EA framework to support big and open linked data and cloud computing [24,26].…”

“…For instance, government EA frameworks that have been used in Colombia [38], Finland [37], Indonesia [20], Brazil [41] were presented. More specifically, the EA framework including the architecture and methodology to support using big data and cloud computing was described [24,26]. Similarly, the use of an agile EA framework to develop and implement the cloud-enabled government was proposed [21].…”

“…TOGAF and SONA were used to develop EAs in the case of the volcanoes monitoring system [40] and EA score card was used for validation and assessment. In some studies, Design Science Research (DSR) approach was adopted as the overall method while validation and verification of the proposed framework was performed with more specific methods [26]. Most studies in this group have been performed in a qualitative way except for [16] and [15].…”
