Create and manage Geodatabe

GeodatabaseMultiple feature type storageSub-Groupings of feature types in feature classes

Control security and access in these subgroupsLogically divide large databases into smaller more managable ones

One RDBMS table stores both spatial and attribute dataAttribute behavior can also be stored

Domains and Subtypes

Associating Tables (data joining)

Ability to store attributes in a feature table or in a separate tableAssociate two tables with common keyMust know about table relationship
