However, several other studies report enterprise (Agarwal et al 2017;Rehman and Shamail 2014;Moreno et al 2014;Janssen and Cresswell 2005), hybrid and distributed (Sedek et al 2013;Meneklis and Douligeris 2007), decentralized Ye et al (2013), and multi-agent-based (Usman et al 2006;Zeeshan Ali Ansari and Imran Khan 2008;García-Sánchez et al 2008) architecture as well, which are not addressed in the study by Sedek et al The authors found that the majority of Digital Government architecture implements G2G and G2C, and most of them (59%) adopt Service Oriented Architecture or Web Services. However, the authors claimed that the architecture analyzed lacks detailed descriptions concerning structural and extra-functional properties.…”
