Conceptual Diagram of Geodatabase
Below is a simplified diagram of some of the objects within Geodatabase.标签描述对象之间的关系。
| Label |
Relationship between objects |
|---|---|
| Workspace Factory | An object that allows you to connect to a workspace.The workspace factory is format-dependent.This means that a different workspace factory is used to open an ArcSDE Workspace than to open a Microsoft Access workspace. |
| Workspace | A data source that contains datasets.The workspace represents the actual Geodatabase being created or opened. |
| Dataset | A collection of data that is grouped together.Examples include feature classes,tables,and feature datasets. |
| Table | A container of non-spatial data.It is never part of a feature dataset. |
| 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. |
| Domain | An object that is used to constrain a field in a feature class or table to an allowable value for that field. |
| 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. |
