The Data Hub provides a data portal for inhabitants to provide public data according to the city's
data governance structure. Inhabitants can receive data visualization, Open API and Data Analysis
sand-box services according to their level of expertise in data utilization. The city data within the
data hub can be visualized for easy understanding by inhabitants and can be checked freely in
a web environment. Inhabitants with higher professional knowledge can access the Big Data
environment and receive an analysis environment in which they can perform actual data analysis.

The Data Hub applies the S/W system for blocking poor data inflow through a quality-control
function for input data. The S/W system is also used for overall data management, authentication
management for output data, and for data-traffic management. Security and safety are ensured
by physically dividing the area where configuration and data are stored and utilized, and by the
configuration of security equipment such as APT, DDoS and SIEM.
