5.6 SSC ICT Architecture interfaces

The interface is the median, which stands between the subsystems of one system [14]. There's no
particular owner of an interface, neither intersystem contracts exist to describe the interfaces. Most
interfaces execute typical batch jobs, while almost all require physical interventions to move
generated files between subsystems. In the proposed SSC ICT architecture interfaces play the role
to deliver information between discrete SSC ICT subsystems.

6.1 SSC ICT architecture framework

6.1.1 Identification of needs
The concept of Smart Sustainable Cities (SSC) has risen from the emerging urbanism phenomenon
across the globe, according which the proportion of the international population that will live in
cities will exceed 66% in 2050. The previously given SSC definition provides this document with the

following characteristics for a smart sustainable city:
1. It concerns an urban space with innovative –not necessarily based on ICT‐ features.
However, this document focuses on SSC architecture, where the ICT have a crucial role
amongst the other innovative solutions and city facilities.
