Source Workspace
| The workspace, either a geodatabase or shapefile directory, that contains the schema of data that will be mapped to the target workspace. | Shapefile; Workspace |
Target Database
| The geodatabase that contains the schema of the database to which the source will be mapped. | Workspace |
Output Database
| The file geodatabase that will be created containing the mapping from the Source Workspace parameter value to the Target Database parameter value. | Workspace |
Mapping File
(optional) | An Excel spreadsheet that contains information on how the source features, fields, and attribute value will be mapped to the Target Database parameter value. | File |
Zusammenfassung
Creates a cross-reference geodatabase that the Load Data tool uses to map source data to target data when loading batch data.
Verwendung
The Output Database parameter value can be used as the input cross-reference geodatabase in the Load Data tool.
The Source Workspace parameter value can be a geodatabase or shapefile.
The Target Database parameter value must be a geodatabase.
This tool will create a file geodatabase containing the tables and records required for transforming and loading the Source Workspace parameter value into the Target Database parameter value.
When the schema of the Source Workspace and Target Database parameter values don't match, the mapping file can be used to define how the features are mapped.
The Mapping File Excel spreadsheet requires a specific format. The template is included in the Production Mapping product files for use when defining a custom mapping file.
If no Mapping File parameter value is specified, the cross-reference geodatabase will contain mappings between all feature classes and fields that have the same name.
This tool will provide warnings when mappings cannot be created in the cross-reference geodatabase for the following scenarios:
- An object class (feature class, shapefile, or table) in the source cannot be mapped to an object class in the target.
- A field in a source object class cannot be mapped to a field in the target object class.
- An object class in the target doesn't have a source object class mapped to it.
- A field in a target object class exists but there is no field in the source object class mapped to it.
- An object class is listed in the Mapping File parameter value that doesn't exist in the Source Workspace or Target Database parameter values.
- A field is listed in the Mapping File parameter value that doesn't exist in the source or target object class.
- The field type of a source field doesn't match the field type of a target field and no value mapping is provided.
