 Smart Cities


  • With rapid urbanization, the load on our cities are increasing day-by-day, and there are challenges in management of resources like land water, waste, air pollution, health and sanitation, traffic congestions, public safety and security, besides the overall city infrastructures including road, rail, bridge, electricity, subways, disaster management, sports facilities, etc. 
  • These challenges are forcing many city planners around the world to look for smarter ways to manage them and make cities sustainable and livable.
  • The idea of a smart city as shown in Figure 3.11 makes use of computer and communication technology along with IoT to manage and distribute resources efficiently. 
  • The smart building shown here uses sensors to detect earthquake tremors and then warn nearby buildings so that they can prepare themselves accordingly. 
  • The smart bridge uses wireless sensors to detect any loose bolt, cable or crack. It alerts concerned authorities through SMS. 
  • The smart tunnel also uses wireless sensors to detect any leakage or congestion in the tunnel. 
  • This information can be sent as wireless signals across the network of sensor nodes to a centralized computer for further analysis.

               DATA INDEPENDENCE Any software has mainly two parts, first is the database and second is the application or program which accesses and uses the database. First the database is designed and then the application program are written for it, which heavily depends on database design. sometimes, after the application program has been written there is need to change the storage structure or database design. data independence is all about, the ability to modify a schema definition (i.e. storage structure) in one level without affecting a schema definition in the next higher level.  There are two levels of data independence. 1. physical data independence : physical data independence is the ability to modify the physical schema without causing application programs to be written. 2.logical data independence : logical data independence is the ability to modify logical schema without causing application programs to be rewritten. ...
