“…Compared to other architecture, our study develops the architectural approach based on architectural principles that address three main problems related to one-stop e-government portal integration and interoperability, architectural structure, service sharing and reuse. Other works are more focussed on Reference Architecture for Government Data Interoperability (Cenci, Fillottrani, & Ardenghi, 2017), Enterprise Architecture for e-Government (Agarwal, Thakur, & Chauhan, 2017), Cloud Service Architecture (Aubakirov & Nikulchev, 2016;Mosa, El-Bakry, El-Razek, & Hasan, 2016) middleware for integration (Chaabane et al, 2015), and SOA e-government for cross-border information sharing (Paul, 2015;Paul & Paul, 2014). The architectural principles provide the guidelines to ensure the architecture fulfils the main role of a one-stop e-government portal.…”
