GIS data vs Geodatabase dataset | Difference between GIS data and Geodatabase dataset
This page compares GIS data vs Geodatabase dataset and mentions difference between GIS data and Geodatabase dataset. GIS stands for Geographical Information System. The term Geodatabase is made using Geo meaning spatial and database meaning RDBMS.
GIS | Geographical Information System
• It is business information management system which helps to capture, analyze and represent
spatial information on a map.
• It allows us to make better decisions based on geography.
• The data viewing on this digital map is easier than spreadsheets.
• GIS software runs on computers ranging from powerful server to software on the mobile phone.
• GIS tools help to visualize geographic data as maps, graphs or charts. Hence
patterns and trends can easily be identified unlike spreadsheets.
• The functions of GIS (Geographical Information System) include data entry, data display, data management, information retrieval
and analysis.
• A data model in GIS is mathematical construct which represents geographical objects or
surfaces as data.
• There are three common representations of spatial data used in GIS viz. vector, raster and
triangulated. Each of these are used for particular kinds of information and their analysis.
• GIS is one of the form of geospatial technology. The other examples include
GPS, satellite remote sensing and geofencing.

Geodatabase
• The ESRI® ArcGIS® applications (such as ArcMapTM , ArcCatalogTM
and ArcToolboxTM) work with geodatabases as well as with coverages and shapefiles.
• It is made of two words "geo" meaning spatial and database which refers to RDBMS
(Relational Database Management System).
• It is basically native data storage and data management framework for ArcGIS.
• It acts as organizational tool to store and manage the data.
• It is gateway to advanced GIS capabilities.
