Description

Additional Information

Reverse Engineer From

Specifies whether you want to reverse engineer from a script or dataset

This option is available when Script File is selected.

Connection

Parameter	Description	Additional Information
Connection Method	Specifies the type of connection you want to use. Connection String connects to your cluster using a connection string.
Connection String	Specifies the path to the secure connect JSON file in the following format: C:\<file name>.json	This option is available when Connection Method is set to Connection String

For information on creating JSON file for authentication, In Google BigQuery documentation, refer to the BigQuery APIs > BigQuery API Reference > BigQuery API Client Libraries > Setting up authentication section.

Datasets

System Objects	Specifies whether system objects are included under the Available Datasets
Available Datasets	Specifies a list of available datasets
Selected Datasets	Specifies a list of selected datasets for reverse engineering

Tables

Parameter	Description	Additional Information
Available Tables	Specifies a list of available tables
Selected Tables	Specifies a list of selected tables for reverse engineering

Views

Parameter	Description	Additional Information
Available Views	Specifies a list of available views
Selected Views	Specifies a list of selected views for reverse engineering

Materialized View

Parameter	Description	Additional Information
Available Materialized Views	Specifies a list of available materialized views
Selected Materialized Views	Specifies a list of selected materialized views for reverse engineering

Option Sets

Parameter	Description	Additional Information
Option Set	Specifies the option set template for reverse engineering	Open: Use this option to open a saved XML option set file. Save: Use this option to save the configured option set. Save As: Use this option to save an option set either in the model or in the XML format at some external location. Delete: Use this option to delete an option set.
<Option Set Name>	Specifies the objects to be reverse engineered according to the selected option set. You can edit this list.

Parameter

Description

Additional Information

Option Set

Specifies the option set template for reverse engineering

Open: Use this option to open a saved XML option set file.

Save: Use this option to save the configured option set.

Save As: Use this option to save an option set either in the model or in the XML format at some external location.

Delete: Use this option to delete an option set.

Detailed Options

Parameter	Description	Additional Information
NSM Options	Specifies the naming standard glossary file in the .CSV format
Case Conversion of Physical Names	Specifies how the case conversion of physical names is handled	None: Indicates that the case in the script file is preserved lower: Indicates that the names are converted to lower case UPPER: Indicates that the names are converted to upper case Force: Indicates whether the physical name property of all the logical/physical models is overridden. If this option is enabled, the logical/physical link is broken between the logical and physical name. If this option is not enabled, all logical and physical names are set to the same value after the process completes.
Case Conversion of Logical Names	Specifies how the case conversion of logical names is handled	None: Indicates that the case in the script file is preserved lower: Indicates that the names are converted to lower case UPPER: Indicates that the names are converted to upper case Mixed: Indicates that the mixed-case logical names are preserved

Parameter

Description

Additional Information

NSM Options

Specifies the naming standard glossary file in the .CSV format

Case Conversion of Physical Names

Specifies how the case conversion of physical names is handled

None: Indicates that the case in the script file is preserved

lower: Indicates that the names are converted to lower case

UPPER: Indicates that the names are converted to upper case

Force: Indicates whether the physical name property of all the logical/physical models is overridden. If this option is enabled, the logical/physical link is broken between the logical and physical name. If this option is not enabled, all logical and physical names are set to the same value after the process completes.

Case Conversion of Logical Names

Specifies how the case conversion of logical names is handled

None: Indicates that the case in the script file is preserved

lower: Indicates that the names are converted to lower case

UPPER: Indicates that the names are converted to upper case

Mixed: Indicates that the mixed-case logical names are preserved

Scheduler

Parameter	Description	Additional Information
Model	Specifies the location and name of the reverse engineered model	For example: C:\Scheduler\<Model Name>.erwin When you schedule a job on a remote server, ensure the model path is same for remote and local server.
Mart Folder	Specifies the location or library in your mart where the reverse engineered model is saved	To use this option, ensure that you are connected to a mart. For more information, refer to the Connecting to Mart topic.
Complete Compare	Specifies whether the Complete Compare (CC) process should run while reverse engineering
Output File	Specifies the location of the CC output file generated
File	Specifies that the target model location is on the local system
Mart	Specifies that the target model location is in the mart
Using Latest Version	Specifies whether the target model is the latest version of the model in the mart	This option is available only when Mart is selected.
Save To Mart	Specifies whether the reverse engineered model is saved to the mart	This option is available only when Using Latest Version is selected.
Target Model	Specifies the location of the target model for CC
Option Set	Specifies the option set that is used for CC	Advanced Default Option Set: Indicates that all erwin DM metadata is included. CC works slowest with this option. Speed Option Set: Indicates that only the essential metadata is included. CC works the fastest with this option set. Standard Default Option Set: Indicates that standard metadata is included. CC works fast with this option set compared to the Advanced option set. In addition to the above options, click Browse to select a custom option set for complete compare.
