Conceptual Diagram of Geodatabase
Below is a simplified diagram of some of the objects within Geodatabase. Labels describe the relationship between objects.
Label |
Relationship between objects |
---|---|
Dataset |
A collection of data that is grouped together. Examples include feature classes, tables, and feature datasets. |
Domain |
An object that is used to constrain a field in a feature class or table to an allowable value for that field. |
Feature Class |
A container of spatial data. It may be part of a feature dataset, or standalone. |
Feature Dataset |
A container of feature classes. All the feature classes within the feature dataset share the spatial reference of the feature dataset. |
Subtype |
An object that is used to separate rows (features) in a table (feature class) into different groups so that different default values or validation rules can be used for each group. |
Table |
A container of non-spatial data. It is never part of a feature dataset. |
Workspace |
A data source that contains datasets. The workspace represents the actual Geodatabase being created or opened. |
