Define Data Sources


In a smart city, data is collected from a variety of sources (Gharaibeh et al. 2017) (Chen et al. 2013). Therefore, the objective of this activity is to define what will be the data collection sources for a given service offered to citizens.



  • A city service consumes different data sources from the city.



In order to provide an efficient service, the data manager needs to plan how to manage the data throughout the process which will be used to provide services to citizens (Gharaibeh et al. 2017) (Sinaeepourfard et al. 2016). Therefore, it is necessary that to identify where the data will be collected, in order to plan the activities that constitute the lifecycle, which should be used to transform the data into information and thus reach citizens as a service.
