Abstract

GIS, like other information systems, consists of sub systems.
• Data entry sub-system;
• storage and data-recovery Subsystem;
• processing and data analysis Subsystem;
• Information outlet Subsystem.

A system can be called a GIS whose software system includes all four of the above functions. Consequently, most digital mapping systems, remote sensing systems, and thematic mapping
systems are not GIS.
Today, database management and analysis are important functions, but in the future, modern functionalities such as the use of artificial intelligence or visualization might come about, which will be among the most prominent features of GIS, and there is no reason why GIS should be limited only to the technology.
