Following sections explain the reverse engineering options for Cassandra.

Parameter

Description

Additional Information
Reverse Engineer From Specifies whether you want to reverse engineer from a script or keyspace

Keyspaces: Indicates that the model is reverse engineered from keyspaces

Script File: Indicates that the model is reverse engineered from a script

 
File Specifies the script file location This option is available when Script File is selected.

Parameter

Description

Additional Information
Connection Method Specifies the type of connection you want to use. Select Direct to connect to your cluster directly. Select Connection String to connect to your cluster using a connection string.  
Hostname/IP Specifies the hostname or IP address of the server where your cluster is hosted This option is available when Connection Method is set to Direct.
Port Specifies the port configured for your cluster  

SSL Certificate Path

Specifies the path to the SSL certificate file

 
Connection String

Specifies the path to the secure connect ZIP file in the following format:

C:\<file name>.zip

For example, C:\TempCass\secure-connect-testdb.zip

This option is available when Connection Method is set to Connection String.

Parameter

Description

Additional Information
System Objects Specifies whether system objects are available under Available Keyspaces  
Available Keyspaces Specifies a list of available keyspaces  
Selected Keyspaces Specifies a list of selected keyspaces for reverse engineering  

Parameter

Description

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

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  

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
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
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.

Compare Level

Specifies the selection type for the compare

Logical / Physical: Compares all objects on the logical or physical level of a model

Logical: Compares all objects on the logical level of a model

Physical: Compares all objects on the physical level of a model

Database: Compares all objects on the database level of a model

Parameter

Description

Additional Information
erwin Project Specifies whether to configure the model for an existing erwin project  
Model Name Specifies the name of the erwin project  
Location Specifies the location of the project
