B.3 Data: Data is the most important component of a GIS. Geographic data and related tabular data can be collected in house, compiled to custom specifications and requirements, or purchased from a commercial data provider. A GIS can integrate spatial data with other existing data resources, often stored in a DBMS. The integration of spatial and tabular data stored in a DBMS is a key functionality afforded by GIS.

People: GIS technology has limited value without the people who manage and develop plans for applying it to real world problems. GIS user range from technical specialists who design and maintain the system to those who use it to help them perform their everyday work. The identification of GIS specialist’s vs. end users is often critical to the proper implementation of GIS technology. This is what called ‘brain ware’ which is equally important as the Hardware and software. Brain ware refers to the purpose and objectives, and provides the reason and justification, for using GIS.

Methods: A successful GIS operates according to a well designed implementation plan and business rules, which are the models and operating practices unique to each organization.

For many years, though GIS has been considered to be too difficult, expensive, and proprietary. The advent of graphical user interface (GUI), powerful and affordable hardware and software, and public digital data has broadened the range of GIS application and brought GIS to mainstream use.
