ArcGIS works with different GIS and non-GIS file formats. Some were created by ESRI such as coverage, shapefile, geodatabase and non-ESRI products such as AutoCAD, MIF/MID, and others. The geodatabase is the built-in data structure for ArcGIS and is the primary data format used for editing and data management. Geodatabase combines “geo” (spatial data) with “database” to create a central data repository for spatial data storage and management. It can be leveraged in desktop, server, or mobile environments and allows you to store GIS data in a central location for easy access and management.
