IDC research defines a smart city as a limited entity (alive; town; city; province; municipal; urban region) have an authority power at the regional level more than at the state level.

This entity is built on a communications infrastructure and information technology that enables to conduct of a city efficiently and promotion of economic development and sustainability, creativity, and the participation of citizens [1].

The advantages of smart cities are: [1]


The data represents the most important elements that support the success of the city’s transformation into a smart city, this transformation is considered successful, and the city should be able to collect data from existing government systems, internet applications, mobile devices, and citizens.

The data collected can be used to make automatic decisions based on proven information, which contributes to improving the lives of citizens.- Smarter cities consist of multiple layers; each containing techniques that assist in data production; classification, analysis, and the ability to respond optimally and effectively, it includes:

  • Connection Layer: This layer includes all types of communication, such as cellular communication (3G-4G-5G) and Wi-Fi technology, Bluetooth technology. These kinds of connections can be ensured by companies and municipalities, or various government agencies, and make strong communication infrastructure allows cities and access to data and deal with it effectively.
  • Datacenter Layer/Operational: This layer ensures the data is held in the data repository and deal with it effectively by all departments and applications.
  • Layer Analytics: Cities benefit through this layer from all the data collected, and to analyze and turn them into valuable insights and activities, cities are increasingly turning to big data analysis that enables them to use predictive analyzes, implementing guidance measures to optimize the allocation of available resources.
  • Layer Applications: In this layer, cities implement sector-specific applications and applications for different user segments. These applications enable data entry acquisitions and collections across different platforms. This layer provides users with an integrated experience by implementing applications capable of integrating services between different entities.
  • End-Users Layer: It is the mainstay in any smart city, ranging from individual and public bodies to private companies. This layer is where data is collected through all applications, and it benefits from the products of smart city initiatives.


Data production is accelerating at an unprecedented rate; the data world is expected to reach 44 zettabytes by the year 2020 [2].

Cities recognize that becoming smart cities requires increasingly big data technology, to be activated across different data entry channels, enabling them to derive good insights and ensure a str ategic decision-making process. Also the city’s ability to respond to information, data collection, and protection it is essential for her to become an information-based city in order to make the transition to smart cities the following aspects of data need to be considered:

  • Data Source Integration: Cities will need to ensure that data is obtained from various source, and cities will need to determine how data is classified and archived and to determine the levels of rights of different public and private entities to access data in the early stages, cities will have manage issues related to data interoperability by different administrations and manage their quality and formulas, cities should also link and cooperate between old and new environments and data being produced.
  • Big Data Analytics: Cities will be able to ensure valuable insights by leveraging analytics, and big data technologies provide predictive analytical solutions to users and businesses and measure performance.
  • Governance Information: Governments will have to deal with how data is being managed, to balance the data with its confidentiality and access.

  • [1] Help to build operational competencies and implement them toprovide services to citizens and companies, including electronicsendees, to obtain approvals and business permits. • Create an environment that attracts foreign direct investment andmaintains economic growth, which contributes to building an urbanenvironment and strong business procedures. • Support growth, innovation, and accelerating the pace of adoption oftechnology, such as using citizen's and companies’ data to developinnovative new sendees or applications. • Ensure a high level of participation of citizens and providing a betterquality of life. Smart cities will enable citizens to provide their opinions and observations and connnunicate directly with authority.
