Data Architecture and Big Data Analytics in Smart Cities.

The smart city has become a persistent need and is no longer just a concept. The concept of smart cities heavily relies on collecting enormous amounts of data. This paper proposes a data-management-based solution for smart city, which is labeled Smart Systems Oriented Big Data Architecture. Big data technologies have become essential to the functioning of cities. The architecture includes complex components to be implemented based on the architectural requirements. A data migration strategy was proposed to handle the various data sources such as IoT devices, video cameras, and drones. The proposed approach also takes into account data processing and data storage. The technical constraints related to data processing in a big-data environment are also studied. We also consider data modeling from a business intelligence point of view and a data science perspective. Our main goal is to favor the facilitation of the daily life practices in the context of a smart city by providing the city administrators with a solution that helps them maintain their city smartly and effectively.
