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
Relationships
One – to – OneOne – to – ManyMany – to – OneMany – to – Many
One to One
Many to one
